Executive Summary of the deliverable
Work Package 6 (WP6) deals with the testing and exploration of new functions relating to Fixed Mobile Converged (FMC) networks proposed by partners involved in WP6 and from analysis performed in other COMBO work packages. WP6 comprises three sub-tasks, task 6.1, task 6.2 and task 6.3. Task 6.1 is an on-going task spanning the whole life of the work package and is used to arrange, plan and monitor the lab and development activities in T6.2 and the operator based experimental task in T6.3.
This deliverable is the first deliverable within WP6, and is used to allow all partners involved in Task 6.2 and Task 6.3 to describe their anticipated focus areas for practical laboratory activities which may include simulation, measurements and development of technology beyond state of the art, as well as field trial or realistic use case measurements in an operators lab or network.
WP6 activities are intended to focus on convergence related topics, taking input from WP3 and WP4 and providing a vehicle to test FMC architectures or component elements. The work should include collaboration efforts with other partners and identify any development activities which can be described as progress beyond state of the art.
D6.1 is the document which will be used to allow WP6 to communicate its initial intentions, and to allow intra Work Package tracking and reporting.

1 INTRODUCTION
This document aims to compile the various partner contributions towards Task 6.1 which form the basis of subsequent tasks T6.2 and T6.3. It is used to align the task activities in such a manner that potential gaps and overlap can be identified and managed throughout the work package.
The following sections capture for each partner involved in T6.2 and T6.3, a proposed description of their activities which is being shared so that other partners have visibility of planned activities across the work package to aid in establishing collaboration activities, identify the relevance of the activities with respect to convergence and to identify the potential for progress beyond state of the art.
The document then summarises these activities in a table to show in a concise way, the coverage of the Work Package.
A section considering gaps and overlap follows which is used to highlight any potential gaps in the coverage of the work package.
Finally a summary of the deliverable is provided at the end of the document.
2 PLANNED CONTRIBUTION PER PARTNER

planning and preparation phase. Floor, rack space etc. and also measurement equipment in cooperation with other DTAG units could be provided on a priori notice. Within the scope of the points listed in Erreur ! Source du renvoi introuvable. DTAG is interested to discuss with the other partners, especially vendors, the potential to host some experiments in DTAG lab.
2.1.5 Field Based Activities
At current state DTAG does not plan to perform trials on DTAG infrastructure. However, on request by partners, DTAG could be able to give access to a fixed line network in Berlin currently used for NGOA trials. Only limited measurement equipment could be provided. However, DTAG plans to support the France Telecom field trials on France telecom premises by joining the discussions and experimental work.
2.1.6 Progress Beyond State of the Art
DTAG will work with WP6 involved partners to demonstrate FMC concepts or aspects of FMC scenarios according to network scenarios and use cases defined in WP3 and WP2. DTAG is basically interested in the following topics:
• NG-POP functions and implementation for fixed and mobile services.
• Fronthaul (e.g. CPRI transport) evolution and Cloud RAN/BBU hotel.
• Converged backhaul architectures/equipment for residential, business and mobile customers.
• Integration of WiFi for e.g. new offloading mechanisms and supporting mobile networks.
• Supervision and performance monitoring in a multi-operator/ multi-vendor environment.
• Investigation of the potential of SDN in the access and aggregation network for FMC.
The exact topics which will be investigated and supported by DTAG will be synchronised with interest on other operators and vendors.
2.2 TID
2.2.1 Scope of work
The main activities related to TID in WP6 are focused in Task 6.1 and 6.3 as TID is not going to be related directly to the manufacturers’ development of FMC solutions, but only during the coordination of the task and the final operator based experimental phase.
More in detail TID will participate in:
• Collaboration in the gap analysis, in test bed scenarios design and in the test plan selection, preparation, execution and validation with the collaboration of the industrial partners.
Grant Agreement N°: 317762
Deliverable 6.1 - Technology Lead Practical Work - Partner Activities
Doc. ID: COMBO_D.1_WP6_ADVA-UK_4July2013_v1.0 Page 14 of 34 Version: v1
• Collaboration in the test activities and definition of planned experimental activities.
• Participation in the discussion with other operators and manufacturers on the preparation activities for Task 6.3 experimental test in laboratory and in field.
• Participation in the test plan definition, test case detailed description, implementation, execution and validation with the collaboration of the rest of the partners.
• Collaboration in the test result documentation and analysis of the results.
• Hosting of laboratory tests for some specific scenarios developed in WP6.
2.2.2 Convergence Focused Tasks
TID is interested in many of the possible scenarios that will be developed inside WP6, for a reference list of what are the main topics see section 2.2.6. Main tasks have been described in the previous section.
2.2.3 Collaboration Activities
See collaboration activities in the previous sections.
2.2.4 Lab Based Activities
TID will be able to host laboratory tests, or specific sections/scenarios of the general experimental phase during any of the three years of the project.
TID can provide the main lab infrastructure (racks space, power, connectivity, etc.) and some of the required measurement and test equipment (optical power meters, optical variable attenuators, optical spectrum analysers, traffic generators, fixed access networks equipment, servers to simulate services, etc.). Due to the size and weight of such equipment and also due to its availability to other project teams, it can’t be moved from Telefónica’s premises to any other partner’s premises.
2.2.5 Field Based Activities
TID doesn’t foresee to propose a field trial using real Telefónica’s infrastructure (that is, the same equipment and communications lines used to provide services to final users), anyway during the beginning of the 2nd and 3rd project year, some specific test scenarios could be proposed and considered for a field trial using Telefónica’s infrastructure.
2.2.6 Progress Beyond State of the Art
TID will work with all partners to demonstrate FMC concepts. The most relevant topics for TID are:
• NG-POP functions and implementation for fixed and mobile services.
• CPRI transport evolution and Cloud RAN.
• WDM-PON architectures for residential, business and mobile customers.
• Resource optimisation and resilience related scenarios.

• Elaboration of Test plans of FMC technical solutions.
• Definition of experimental setups for tests of FMC technical solutions.
• Follow the development and tests of the solutions proposed by the industrials.
• Analyse test results.
• Host system tests.
2.3.2 Convergence Focused Tasks
According to different use cases and network scenarios defined in WP2 and WP3, France Telecom will discuss with the different partners on the potential implementations to test either in the lab or during the final field trial demonstration.
2.3.3 Collaboration Activities
Tests activities aim at assessing FMC architectures and industrials implementation and France Telecom will take part in test proposals for architectures defined in WP3 and definition of experimental setups.
2.3.4 Lab Based Activities
France Telecom has several service platforms for fixed and mobile networks. Also, it will be possible to involve high bandwidth real time multimedia services (UHD, 24Mbit/s HD streams) and classical services like Internet, VoIP and HD VoD.
It will be possible to demonstrate CPRI links between BBU and RRH in the case of data bit rates up to 10Gbit/s. For mobile, it will be possible to use UMTS and LTE equipment.
In the lab, we also have Ethernet generator / analysers and CPRI emulators and it is possible to consider physical tests, performance tests (throughput, latency, and packet loss ratio…), and tests of functions to support business and residential services, evaluation of power consumption, etc.

2.3.5 Field Based Activities
France Telecom proposes to host final field trial and to place optical and mobile infrastructure at COMBO’s disposal. In this context, it will be possible to:
• Access to the Residential service platforms.
• Use the Mobile network and CPRI emulators.
• Involve Ethernet generators / analysers and dedicated instrumentation needed for the test setups defined with the different COMBO’s contributors.
• Test synchronisation issues on FMC systems.
2.3.6 Progress Beyond State of the Art
France Telecom is particularly interested by the following topics:
• NGPoP architecture and concept.
• Considered technical solutions for FMC system design.
• Support of fixed and mobile services on optical fibre infrastructure involving NGPON2 approach in system design.
• QoS mechanisms managing several types of customers in the same machine (residential, business and mobile customers).
• Performance monitoring.
• Aggregation capacity evolution and detection of congestion points.
• Synchronisation topics.
2.4 ALU-I
2.4.1 Scope of work
ALU-I is involved in Tasks 6.2 and 6.3. However even if not formally planned in the DOW, ALU-I will participate to the discussion within Task 6.1 with the goal to identify the Lab and Field activity, coherently to the activity developed in WP2 and WP3. Furthermore external coordination with standard bodies and other EU projects will be carried out.
2.4.2 Convergence Focused Tasks
Provided that ALU-I focus will be mainly on aggregation networks, our approach will be in the direction to guarantee an evolution towards FMC Network by introducing new feature on existing equipment. Among them we identify QoS, low latency network, synchronization mechanism, low cost optics and CPRI backhauling. Those topics need to be further discussed and harmonised.
2.4.3 Collaboration Activities
On top of the natural coordination with other COMBO WPs, in particular with WP2 and WP3 in our case, some external collaboration has been proposed, addressing the topic of “low cost” optical solutions and power management. In particular we are
Grant Agreement N°: 317762
Deliverable 6.1 - Technology Lead Practical Work - Partner Activities
Doc. ID: COMBO_D.1_WP6_ADVA-UK_4July2013_v1.0 Page 17 of 34 Version: v1
willing to facilitate possible exchange between standardisation activity and parallel FP7 project currently dealing with those topics and in which we are working as a partner.
2.4.4 Lab Based Activities
The COMBO activity is supported by Optics division R&D. This fact implies that the focus will be mainly on the aggregation network. In particular, with reference to the Figure 1, lab activity will be developed around 1850TSS and 1830PSS products.
This choice will allow managing smooth transition between the today network aggregation architecture and the FMC by adding new features and functionality on those products. In particular key elements are considered QoS, reliability synchronisation that could be addressed by the available network layers (i.e. DWDM, OTN, and MPLS-TP).
Figure 1: ALU-I Experimental Focus Area
2.4.5 Field Based Activities
ALU-I see the opportunity to integrate part of the lab activity in a more wide and general demonstrator(s) addressing end-to-end application in the new FMC target environment. This activity will need a strong coordination activity between all participating parents to converge to a common setup. This effort will be mainly driven by the operators.

2.4.6 Progress Beyond State of the Art
ALU-I will work to identify and experiment new features in the aggregation network areas aimed to contribute to COMBO FMC vision. We already indicated the main topic in the previous chapter: QoS, low latency network, synchronisation mechanism, low cost optics and CPRI backhauling.
2.5 EAB
2.5.1 Scope of work
EAB will take part in all activities, i.e., tasks 6.1, 6.2 and 6.3 of WP6. In Task 6.1 we participate in collection and analysis of work of the other WPs. We will also take part in gap analysis, exchange of information & collaborate with industrial partners and operators in specifying the Lab based activity. We will also work closely with the operators that will cooperate with us in realising the field based activities.
2.5.2 Convergence Focused Tasks
EAB will work and demonstrate a converged network architecture solution, catering both fixed and mobile services. The architecture will also demonstrate the convergence of an access and metro networks.
2.5.3 Collaboration Activities
EAB will collaborate with operators within the WP6 to:
• Reviewing the work in WP3 and WP4.

We will present and demonstrate a novel future proof DWDM centric converged access metro network architecture using few optical modules, such as OADM, WSS and DWDM transceivers which traditionally have been used in the transport network but due to technology maturity of optical components are predicted for major cost reduction. The demo also includes a control and management block including discovery unit and wavelength controller blocks, for demonstrating some basic SON functionalities, such as automatic node discovery and automatic connection set-up and wavelength assignment. The main features shown in the demo are:
• Support of residential, enterprise and mobile traffic transport.
• High capacity, low latency connectivity between access and service edge nodes.

• Support of centralised Baseband Units’ deployment.
• Bitrate and protocol transparent connectivity.
• High availability connections.
• Auto discovery of end node connections.
• Auto set-up of wavelength connectivity between access and service edge nodes.
2.5.5 Field Based Activities
In the field based activities, we intend to further develop the network architecture. Starting with the network novel architecture demonstrated in the Lab, we will work on:
• Automated device connection and configuration.
• Enhance the discovery of multiple types of hardware and types of services.
• Demonstrate flexibility and agility by introducing tune-ability in the network.
• Demonstrate features to handle various failures.
• Small cell backhaul and centralised BBU solutions.

2.5.6 Progress Beyond State of the Art
EAB will work together with operators to explore and demonstrate FMC network & simplification with a novel network architecture blurring the distinction between the access and metro networks. We will explore network simplification by decoupling services from the transport technologies and delegating the network intelligence only at the edge of the access and metro networks. We will work & demonstrate novel link technologies for small cell backhauls, centralised BBU solutions and SDN functionalities in the context of FMC.
2.6 ADVA-UK
2.6.1 Scope of work
ADVA-UK will be providing input to Work Package 6 as Work Package Leader and Task Leader for T6.1 and T6.2 which are primarily coordination and reporting roles. Specifically in this role ADVA-UK will:
• Maintain a list of inputs from other WPs.
• Coordinate regular update sessions to enable the exchange of information, status, and provide the forum for discussion on gap analysis, findings and results.
• ADVA will ensure that a repository or index of all published material relating to results is available throughout the project.
Grant Agreement N°: 317762
Deliverable 6.1 - Technology Lead Practical Work - Partner Activities
Doc. ID: COMBO_D.1_WP6_ADVA-UK_4July2013_v1.0 Page 20 of 34 Version: v1
ADVA-UK will be participating in T6.2 Lab based activities, designing and constructing a test and measurement environment suitable for exploration of FMC access and aggregation network characteristics and OAM, with particular interest in synchronisation and timing related activities as well as exploratory fronthaul QoS and Performance Monitoring (PM) techniques if time allows.
ADVA-UK in collaboration with ADVA-DE will work with operators and other partners in T6.3 to develop and perform experiments on realistic infrastructure test environments, building on the results obtained from T6.2 lab based activities.
2.6.2 Convergence Focused Tasks
Current synchronisation reference models typically assume topologies which might be considered more representative of legacy core network architectures, rather than the requirements and topologies seen in current fixed and mobile access and aggregation networks, or those anticipated for future converged networks.
Work will focus on development and evaluation of models applicable to future FMC architectures and applications by exploring Network Function Virtualisation and SDN topics in the access and aggregation networks.
2.6.3 Collaboration Activities
In addition to ADVA-UK’s coordination role within T6.1, we will collaborate with other partners during the planning and execution of the lab and field based activities of T6.2 and T6.3.
ADVA-UK is keen to work with research groups on emulation of synchronisation reference networks, and other vendors where interoperability or multi-vendor scenarios are applicable.
2.6.4 Lab Based Activities
Activities considered include the design and construction of test and measurement environment suitable for exploration of FMC access and aggregation network characteristics including NFV, low latency traffic interconnect, and Synchronisation as a Service (SaaS). Topics explored by ADVA-UK will be drawn from the list of activities below:
• Study of the applicability of standardised (hypothetical) reference models for synchronisation networks (e.g. ITU-T G.8261) to various FMC use cases and deployment scenarios.
o Development and lab evaluation of candidate alternative models more directly applicable to the planning and performance prediction of real world FMC networks incorporating different physical layer technologies (e.g. WDM-PON, point-to-point fibre, etc) and protocols (e.g IEEE1588 over MPLS, CPRI etc.).
• Study of passive and active monitoring techniques for QoS and fault isolation / prediction with particular emphasis on network latency and synchronisation performance.
Grant Agreement N°: 317762
Deliverable 6.1 - Technology Lead Practical Work - Partner Activities
Doc. ID: COMBO_D.1_WP6_ADVA-UK_4July2013_v1.0 Page 21 of 34 Version: v1
• Evaluation of various metrics as KPI’s for the monitoring and prediction of synchronisation and latency performance.
• Exploration of integrated end to end QoS / performance management and fault location across backhaul and fronthaul networks
• Testing will be based on a combination of simulation, emulation and physical testing by ADVA and collaborating partners.
• Where feasible, ADVA-UK intends to monitor energy consumption of various solutions and provide comparisons since multiple solutions may be available to achieve the same goal. Where feasible, energy reduction techniques such as sleep modes will be analysed, although this is a stretch goal rather than a mainstream focus for our activities.
2.6.5 Field Based Activities
ADVA-UK in conjunction with ADVA-DE will work with operators and other partners to develop and perform experiments on realistic infrastructure test environments, building on the results obtained from T6.2 lab based activities.
2.6.6 Progress Beyond State of the Art
ADVA-UK will develop KPI’s and planning models directly applicable to the planning and operation of FMC networks with particular emphasis on latency and synchronisation performance.
ADVA-UK will also contribute to the improvement of various standards; in particular (but not exclusively) in relation to synchronisation and timing. The aim is to address the requirements of future FMC networks and applications.
Exploring potential applications of “Carrier Ethernet” level QoS and performance monitoring concepts to mobile fronthaul segments within a FMC network, is considered to be progress over current state-of-the-art fronthaul protocols such as CPRI.
Enablers for NFV approach to access and aggregation solutions are currently a hot topic in the standards community and industry. ADVA-UK sees adoption of NFV topics as having a high potential to move the industry forwards.
2.7 CTTC
2.7.1 Scope of work
CTTC participates in both T6.2 “Lab based Practical Work & Development” and T6.3 “Operator based Experimental Task”. In T6.2, CTTC will concentrate on experimentally validating COMBO FMC architectural aspects (e.g., aggregation network supporting mobile and fixed services) through the integration of the CTTC emulated LTE RAN and the deployed packet-based optical aggregation network. Specifically, the following technologies, functions and key architectural elements of such integration will be considered and evaluated:
• Emulation of the E-UTRAN, including:

The final goal of this experimental activity is to automatically set up both “mobile” services between the emulated eNBs and the emulated S-GW/P-GW entity and “fixed” services between MPLS-TP nodes over the optical aggregation network infrastructure. The automatic establishment of these connections within the aggregation segment will be handled by either GMPLS or SDN/OpenFlow control plane. In the considered multi-layer aggregation network, multiple packet connections (Label Switched Paths, LSPs) will be routed over optical tunnels (LSPs). This allows exploiting the coarse transport capacity of the optical connections, wherein packet connections with different bandwidth granularities (e.g., 100Mb/s, 1Gb/s, etc.) are statistically multiplexed and groomed leading to attain the most efficient use of the overall network resources.
In the CTTC particular configuration and setup, within the mobile control, there is permanent control connectivity between the emulated eNBs and the MME and S-GW/P-GW entities through an out-of-band infrastructure. In other words, the implementation of the S1-MME and S11 control interfaces are not routed throughout the aggregation topology segment. When a new mobile traffic service needs to be established, the corresponding LTE control messages among the emulated eNB, MME and S-GW/P-GW elements are exchanged. It is worth mentioning that the CTTC deployed LTE RAN solution is a light implementation of the standard LTE control plane defined by the current 3GPP specifications.
The automatic setting up of the connections, referred to as GPRS Tunnelling Protocol (GTP) tunnels (i.e., S1-U interface), from an eNB to the S-GW/P-GW through the aggregation network could be potentially triggered by designing and implementing a dedicated signalling protocol between the eNB and/or the SGW and the aggregation (either distributed GMPLS or centralised OpenFlow) control plane entity. On the other hand, the emulation of the S1-MME and S11 interfaces, i.e., exchanged LTE control messages could be also captured to actually trigger the establishment of the connections (bearers) and their associated GTP tunnels. In any case, the bearer setup event for a given Packet Data Network (PDN) connection will be mapped to the request of a new packet LSP within the aggregation network. It is important to outline that the requested packet LSP will need to guarantee the specific QoS parameters (e.g., bandwidth, latency, bit error rate, scheduling policy etc.) associated to the corresponding bearer.
The adopted control plane solution in the aggregation network will be the responsible to compute the route satisfying those QoS parameters and, eventually setting up the requested packet LSP over the multi-layer infrastructure.
The objectives, network setup, involved functions, experimental tests and obtained results for both tasks (T6.2. and T6.3) will be reported through the corresponding milestones and deliverables of WP6.
2.7.2 Convergence Focused Tasks
From the description of the proposed experimental activities, the convergence will be focused at the aggregation network level. That is, the deployed packet-based optical network is used to seamlessly transport connections originated at either fixed or mobile access networks. By doing so, such multi-layer network is able to efficiently

converge IP services initiated at both access networks satisfying their specific QoS parameters (in terms of bandwidth and latency) and attaining an efficient use of the network resources (in terms of capacity, optical ports, etc.).
2.7.3 Collaboration Activities
The collaboration with other partners will mainly rely on two aspects:
• Collaborate with operators on defining potential applications as well as traffic requirements, etc. at both mobile and fixed access networks.
• Potential integration with optical access equipment provided by vendors.
2.7.4 Lab Based Activities
The lab based activities will be mainly focused on the deployment of the required control functions and elements to achieve the interworking between the CTTC emulated LTE mobile access and the deployed packet-based optical aggregation network. This will entail the design, deployment of required new functions / parts, implementation and validation of the above interworking for automatically triggering the establishment of mobile connections over the aggregation network. To do so, besides the interworking functions between both mobile and aggregation control plane elements, specific and selected routing algorithms within the aggregation network will be used to compute paths satisfying the demanded QoS parameters while attaining an efficient use of the network resources. The figures of merits for the targeted experimental activity would measure the average end-to-end setup delay, connection blocking under dynamic traffic, etc. Finally, validation of dynamic restoration strategies could be also considered.
2.7.5 Field Based Activities
The described lab based activity deployed within the CTTC experimental platforms could be then reused in a more realistic scenario collaborating with vendor and operator partners. This will require an exhaustive study and discussion of the implications and requirements (e.g., adjustment and tweaking, new functionalities, etc.) for doing such “migration” from a lab environment towards a field trial scenario. In other words, a strong consensus among the participants will be essential addressing very specific and detailed targets.
2.7.6 Progress Beyond State of the Art
CTTC will work on validating and demonstrating selected FMC concepts such as the integration of aggregation and access for the integration of fixed and mobile services. In this regards, from the best of our knowledge, no previous work has experimentally validated the interoperability between the separated control planes used for mobile (LTE) and packet/optical multi-layer aggregation network. This enables the automatic provisioning of mobile and fixed services having their own QoS parameters over the same converged aggregation network. This represents the primary objective and challenge to be done in WP6 by CTTC.

2.8 AITIA
2.8.1 Scope of work
As initially planned in the technical annex, AITIA will take part in lab-based activities in 6.2 as its main WP6 activities. We are also open to take part in field trials and to provide input for gap analysis as well as engage in cooperative activities.
2.8.2 Convergence Focused Tasks
We build a test lab for QoE and QoS measurements mainly related to video content. The aim of these tests is to figure out what factors shape the end-users perception of video quality. During the experiments we use fixed LAN as well as mobile (3G, WiFi) access of video content, and shape the traffic in the core in a way that effect video QoS. The tools for shaping include injecting inter-packet delay and jitter, generation of packet loss, multiplication of the same packet toward the destination, etc. While the video QoE will be evaluated by various users in various conditions of an FMC scenario, various technical quality metrics will also be evaluated by us: PSNR (Peak Signal Noise Ratio), VQM (Video Quality Metric), SSIM (Structural SIMilarity) and others.
Our laboratory equipment is also available for evaluation of synchronisation, delay and jitter of FMC traffic.
As part of the evaluation of the Knowledge Plane concept, we will build a test experiment for a Monitoring/Knowledge/Action Plane scenario, where we will analyse possibilities of automatic configuration functions to facilitate network setup.
The concept of the Knowledge Plane (KPlane), and later the Monitor Plane (MPlane) has been introduced to support Autonomous Networking goals. The tasks of processing the network element-, service-, and traffic-information belong to the MPlane. It feeds the KPlane with valuable information, based on which configuration changes are actuated. Although the concept of KPlane is widely used in various levels of network and service management, general traffic analysis is not yet utilised to support decision making procedures. Traffic mix and traffic matrix analysis results are of major interest in the decision making process at the KPlane.
2.8.3 Collaboration Activities
AITIA has monitoring and traffic analysis capabilities for mobile and fixed core up to 10Gbps at the start of COMBO; and will have equipment available for 100Gbps Ethernet by end of 2013. The capabilities of this equipment (HW and SW) will be utilised in WP2, WP3 and WP4, as well as the laboratory testing activities in WP6.
On the other hand, AITIA has a complex traffic generator equipment, which can provide real traffic patterns into pilot or lab equipment of COMBO partners. The complex traffic generator is practically a 4U 19” PC (not consuming much physical space), able to emulate BSCs, RNCs and eNodeBs as they had 10 of thousands of subscribers attaching, location updating, moving and detaching to- in- from- between- the 2G, 3G and 4G networks. During the test the attached users have pre-set traffic patterns that they load the SGSN / GGSN or the SGW /PGW with.

This equipment can be useful either during laboratory or field testing in COMBO.
2.8.4 Lab Based Activities
Beside the activities listed under section “Convergence Focused Tasks”, AITIA will focus on traffic and performance management issues. The subtasks will include building a lab environment for testing and verification, developing the actual FMC-specific algorithms for SLA verification based on passive monitoring, creating verification methods for the possible impact of future traffic scenarios, providing a prototype for application identification and traffic matrix calculation through passive traffic monitoring.
2.8.5 Field Based Activities
Although AITIA has no planned effort for field based activities in COMBO, we are happy to validate concepts or provide analysis tools if partners identify that their field tests can host AITIA equipment.
2.8.6 Progress Beyond State of the Art
AITIA intend to focus on the topic of Autonomous Networking, and development of FMC-specific algorithms for SLA verification based on passive monitoring, creating verification methods for the possible impact of future traffic scenarios.
By considering traffic mix analysis as part of the decision making process at the KPlane AITIA believe that FMC solutions will be improved beyond current capabilities.
2.9 TELNET
2.9.1 Scope of work
Telnet will take part in the testing approach to assess potential lab-based scenarios, description of the available equipment for structural convergence and development of future technologies in Task 6.2. Furthermore, Telnet will be available for evaluating the interoperability between vendor solutions and operator infrastructures in Task 6.3.
2.9.2 Convergence Focused Tasks
Telnet will be focused on the possible structural convergence between fixed and mobile networks using an innovative architecture based on the coexistence between GPON and WDM-PON. Thereby, the first one is used to provide capacity for residential users and the second one to provide access to the mobile network. Telnet will propose an architecture where the mobile and fixed access networks converge in a shared Passive Optical Network.

Figure 3: TELNET Focus Area
2.9.3 Collaboration Activities
Testing structural convergence is one of the main goals of Telnet in COMBO project. In this way, Telnet could participate with certain partners to deploy and validate our proposed FMC solution based on WDM-PON over GPON in their access networks. This approach will be of benefit for operators that want to improve their communication networks in terms of capacity, size and security.
2.9.4 Lab Based Activities
Available equipment based on Passive Optical Networks will be used in lab-based scenarios in order to evaluate the possible coexistence of GPON over WDM-PON. This scheme can be implemented using different items providing different architectures with not equal features and efficiency.
Telnet will implement and evaluate the advantages and disadvantages of each of them to determine the most efficient FMC solution for real applications.
2.9.5 Field Based Activities
The aim of Telnet is to deploy in field based scenarios the proposed and tested WDM-PON and GPON architecture in order to demonstrate the possible convergence of fixed networks with mobile communications in access stage with Telnet’s FMC solution.
2.9.6 Progress Beyond State of the Art
GPON is a technology which is being currently deployed for Fixed Access Networks. However, due to its characteristics and lack of bandwidth cannot be used in future Mobile Access Networks. At this moment, WDM-PON could be considered a technology at the edge of the State-of-the-Art and is one of the most promising technologies for the FMC architecture due to its transparency to carry any kind of

traffic for Mobile access networks and of course to its flexibility. However, this technology at this moment remains too expensive for fixed access networks. The combination of WDM-PON with GPON in the same access network infrastructure could represent a potential FMC solution. Thereby, the progress beyond of the state of the art resides in the combination of both technologies in the same PON infrastructure to solve the current and future needs of FMC issues, specially the integration of GPON downstream and upstream signals within the WDM-PON spectrum grid.
2.10 ADVA-DE
2.10.1 Scope of work
ADVA-DE will participate in tasks T6.2 and T6.3. This work starts in 2013, and will continue until the end of the project. It covers both, lab- and field-based activities. The lab work intends to build a demonstrator (specified further down below); the field-trial intends to test this demonstrator in a real-world environment.
2.10.2 Convergence Focused Tasks
ADVA-DE intends to perform lab work and support field-based activities with primary focus on transport capabilities for CPRI signals. In particular, ADVA-DE intends to implement low-cost-capable, fibre-based transport for point-to-point and point-to-multipoint (PON-like) infrastructures. This also includes combinations with (Carrier Ethernet) backhaul and similar broadband applications (e.g., business access). As such, relevant aspects of convergence are covered. For CPRI, bit rates between 620 Mb/s and 10 Gb/s shall be covered.
The main rationale of this work is the fact that today, there still are no low-cost transmitters for bit rates >1.2G which are also capable of supporting maximum CPRI distances in excess of 20 km. Tuneable laser diodes are only slowly becoming cheaper, and the ones available do not lend themselves to low-cost approaches in the near future. Alternatively, seeded/reflective transmitters are difficult for / towards 10G (or again are comparatively complex / expensive). The work will concentrate on both, upcoming low-cost tuneable and high-performance (5…10G, >10 km) seeded/reflective approaches. This includes basic performance tests (reach vs. bit rate, pre-FEC BER). Further relevant targets include lowest system latency (sub-millisecond total), and the possible integration into a backhaul/fronthaul system. Focus will also be put on the potential for energy-efficient implementation.
2.10.3 Collaboration Activities
In principle, ADVA is open for any type of cooperation with project partners. In particular, for field-based activities, we will seek cooperation with the related operators, although collaboration activities will need to be defined with more detail in the future. ADVA-DE also intends to integrate work from other EU projects such as PIANO+. Here, we can bring in latest results from the photonic-components-oriented projects TUCAN and IMPACT. These projects aim at developing low-cost transceiver components which can be used for WDM-PON or passive-WDM systems. As such, these projects may be helpful in solving the low-cost CPRI transceiver problem. (A

similar approach was followed in the FP7 project OASE. Due to delays in the PIANO+ projects, the respective results could not be used in OASE anymore. We now intend to use the results in COMBO instead.).
2.10.4 Lab Based Activities
ADVA-DE will investigate possibilities which will lead to low-cost transport of CPRI signals (intended for C-RAN), together with other signals such as Ethernet (as used for backhaul and/or business access). Focus is to integrate this transport capability into a WDM-PON or passive-WDM (pWDM) system. Special focus will be put on suitable transmitters for signals up into the 10-Gb/s range, and distances up into the 20…40-km range. This can be first samples of low-cost tuneable laser diodes, or REAM-SOA combinations (Reflective Electro-Absorption Modulators with integrated Semiconductor Optical Amplifiers) for seeded/reflective approaches.
2.10.5 Field Based Activities
ADVA-DE intends to participate in field trials. Details shall be planned during second half of 2013 and first half of 2014. In this context, ADVA-DE will collaborate with FT/Orange and possibly DTAG. In this context, CPRI emulators will be of particular interest since CPRI transport tests in a real-world environment is the primary goal. Depending on progress in T6.2, this can be combined with transport capabilities for Synchronous Ethernet for wireless backhaul.
2.10.6 Progress Beyond State of the Art
We expect to achieve progress beyond the current state-of-the-art in that we successfully integrate CPRI with bit rates up to 10 Gb/s into a WDM-PON / pWDM lab system which can also be used for general backhaul, business / SME access and similar applications. The respective technology must have low-cost, low-latency, and low-energy-consumption capabilities.
2.11 FON
2.11.1 Scope of work
Fon will participate in the three subtasks that compose the work package:
• Collaborate in the test setup and scenario definitions.
• Collaborate on performing lab tests.
• Collaborate on performing field tests.
2.11.2 Convergence Focused Tasks
Over all Fon is interested in the offloading from mobile networks onto Wi-Fi as the key point in this work package. This type of feature requires both client and network to be FMC aware in order to perform actions without user interaction.
2.11.3 Collaboration Activities

2.11.4 Lab Based Activities
Fon has interests in performing lab tests that allow testing of offloading features previously described. In these tests the following key points are of interest for offloading case:
• QoS requirements.
• Mobility management between the mobile network and the Wi-Fi access.
• Handover mechanisms between technologies.
• Performance monitoring.
Fon lacks the needed test bed for performing the testing of the functions regarding the mobile network and would like to collaborate in this area.
The lab based activity will be focused on testing different technologies that enable new offloading mechanisms that answer the offloading use cases described in WP2 and that ensure the feasibility of the architecture and network scenarios of WP3 in the degree that they are related to the offloading topic.
2.11.5 Field Based Activities
Fon will collaborate with partners in performing field activities in order to test the featured previously developed in the lab environment but in a larger scale in order to identify possible scalability issues of the solutions.
Regarding the field test environment, Fon cannot provide access to already deployed production environment devices. Additionally, Fon does not have test facilities to host the field tests, but can provide a reduced set of Foneras to perform tests in a controlled environment with the services offered by Fon. With those Foneras, a residential or public Wi-Fi environment could be simulated in order to test how the offloading would behave in such cases.
Mobile operator collaboration is sought in the field testing area in order to be able to correctly design, test and assess the results for the mobile network component of an FMC network.
The expected output of the field tests shall quantify the impacts the inclusion of offloading techniques may have in an FMC network, both in its mobile and fixed parts accessed through Wi-Fi.
2.11.6 Progress Beyond State of the Art
Fon has interests in progressing offloading techniques that would allow transferring user traffic from the mobile network to the fixed network through Wi-Fi in an FMC network. This includes data and voice offloading as well as QoS management.

Table 1: WP6 Topic Areas Summary
The table above captures the key topics arising from the contributions made by partners involved in WP6. In comparison with the objectives of WP6 as set out in the technical annex during project application, it can be appreciated that the topics meet if not surpass the originally planned topics.
Grant Agreement N°: 317762
Deliverable 6.1 - Technology Lead Practical Work - Partner Activities
Doc. ID: COMBO_D.1_WP6_ADVA-UK_4July2013_v1.0 Page 33 of 34 Version: v1
Some topics have multiple partners involved and therefore it is hoped that multiple solutions can be compared from WP6 activities and the best of these shared with other WPs such as WP5 for further analysis.
4 POTENTIAL GAPS AND OVERLAPS
This section is used to capture the outcome of WP6 reviews which explored gaps and overlap within the work package.
Many partners from the vendor and research community have identified a wide range of topics to explore in laboratory environments. The topics identified fit well with the original anticipated work captured in the DOW, and could be said to surpass the original plan.
From the operator side there is keen interest for convergence studies to take place in the later field trial task 6.3.
During earlier reviews of the WP6 activities, a gap in coverage relating to energy monitoring and steps to support energy reduction was identified. The partners have explored this topic and we believe that energy monitoring is now captured by at least one partner. Other partners have proposed to add support of energy reduction into their activities as a stretch goal.
To a certain extent, one could say that there is potential for overlap on some topics especially WDM-PON, PON and Cloud-RAN, however, it is felt that having multiple partners exploring these topics will lead to two productive outcomes, one of which is the potential for collaboration, the other is alternative methods of achieving the same solution, enabling comparison studies to take place. Outputs from WP6 could perhaps be analysed in other work packages i.e. WP5 to allow an optimum solution to be identified.

5 CONCLUSION
Work Package 6 has a large number of partners that wish to explore topics relating to convergence of fixed and mobile networks. There is as such, a wide coverage of topics ranging from physical layer, passive optical networks, through to transport of radio over fibre using CPRI to enable Cloud-Ran fronthaul models, and then further up the stack, other partners are looking at protocol activities and control plane functions including SDN and NFV. On top of these layers and architectures, functional topics being explored includes content distribution, synchronisation as a service and analysis of video service and QoE via performance monitoring.
At the outset of the work, collaboration is anticipated but not immediately obvious. In later stages and in particular T6.3, we believe that collaboration will be the key to successful completion of the WP. The Work Package Leader and operators involved in COMBO will be exploring methods of improving collaboration as we make progress in WP6.
Progress beyond state of art has been captured by a number of partners in their respective sections, clearly many view transport of CPRI over PON infrastructure for mobile RAN networks at the same time as servicing the wider needs of the fixed aggregation network as a key topic which is classed as progress beyond state of art, while others have identified Cloud-Ran and BBU centralisation, self-organising networks, and topics including SDN, NFV and synchronization as a service.
It is considered that WP6 topics identified in this deliverable will enable an exciting and productive Work Package, as well as being a vehicle to provide experimental results and solution descriptions which can be used to enable dissemination activities from COMBO.
