I. Introduction The purpose of this document is to provide a detailed design for VTN’s Metro DWDM Network in Ha Noi. The material described in this document is primarily base on the System design document and site survey report. This document will provide overview Metro DWDM Network in Ha Noi, network topology, management network, traffic distribution, hardware configuration, as well as internal connections for all nodes.

This document provides information for implementation, operation and management of the network. As with all design documents, it is an undesirable but necessary requirement that this document will be a working document subject to regular change control during the first few months of its conception before document stability can be achieved.

The primary intended audiences are engineers who need be understood how the DWDM transmission, NG-SDH network and nodes are configured in order to deploy, operate and maintain the network.

II. Network Solution Description

2.1 Solution overview

Alcatel-Lucent will present its latest technologies in this project in order to give VTN an outstanding solution for the new generation metro DWDM networks.

The proposed network solution for VTN’s Metro DWDM Metro Links in Ha Noi includes the modern and high quality reconfigurable OADM system, 40G technology and the new generation transport service switch aggregation platform together with a fully integrated end-to-end Network Management System. This solution complies with VTN’s requirements as future-proof optical transmission network.

Alcatel-Lucent Wavelength Selective Switch R-OADM Technology

Reconfigurable OADM have been introduced to the industry in the short time and is considered as an effective new technology, which will be deployed broadly in the future’s transmission network to increase the service flexibility, network reliability and to reduce carriers’ operation cost in terms of the man power and the buffer stock.

The major technology for this network application is the Wavelength Selective Switch (WSS)

The WSS technology is used for realizing ROADM nodes with two or more optical directions (degree) and the need for a system that can deliver the same capacity as WDM, with the design and provisioning flexibility of SONET/SDH. As well as handling the immediate issues, the solution must ensure future flexibility in traffic forecasting.

This technology, thanks to the full tenability of all the lambdas that across or are terminated in the node and the mux/demux filters, allows service providers to automatic reconfigure the add and drop capacity at a node remotely, reducing operating expenses by eliminating the time and complexity involved in manual reconfiguration. Above all, WSS allow the service provider to design an optical network once, and then never have to worry about it again, regardless of how the network grows.

The ability to manage the WDM network like a SONET/SDH network, simply and efficiently, provides significant cost savings through simplified network provisioning, service provisioning, and overall network maintenance. This wavelength management that elevates WSS technology to the level of functionality demanded by today’s service provider, who doesn’t want to cope with the “analog” aspects of WDM transmission — operator-based procedures for wavelength power adjustment, manual reconfiguration for wavelength add and drop, and pass-through and bandwidth stranding due to banded OADMs.

Alcatel-Lucent 40G DWDM Technologies

The sustained growth in traffic on inter-city routes with the new services of high-definition digital TV, high quality teleconferencing, data storage applications, core router interconnection application and so on, continues to drive the metropolitan operators toward ever-higher transport capacity at ever-lower cost per bit per second per kilometer.

In today’s markets, most key components for developing and delivering state-of-the-art 40 Gb/s products have been designed by Alcatel-Lucent teams. These unique products include:

Network Design


A 40 Gb/s forward error correcting (FEC) ASIC that grants full compatibility with the G.709 OTN standard.

A broadly interoperable electrical mux/demux. Often referred to as a SerDes, for Serializer-deserializer, this component has to be used in any 40 Gb/s client interface or 40 Gb/s line interface.

A unique concentration mapper ASIC (which can concentrate any 10 Gb/s client including 10Gb/s Ethernet LAN.

A high performance lower cost 40G modulization technology – DPSK – to reach much longer distance comparing with the 40G other technologies.

Alcatel-Lucent New Generation Universal Transport Service Switch Concept

The industry’s first transport service switch, Alcatel-Lucent 1850TSS, is the next step towards a converged transport network: a single transport aggregation platform that switches packets and circuits and transports any kind of service in any possible mix, enabling service providers to build future-proof transport networks capable of supporting any future traffic requirement.

The Alcatel 1850 TSS builds on an open architecture with the “Universal Switching” concept that integrates data switching (Ethernet), TDM switching (SDH/SONET/PDH) and WDM switching, configurable in any mix for any transport need. This unique capability makes the Alcatel 1850 TSS the ideal building block for the ongoing transformation of transport networks, enabling service providers to flexibly split increasing traffic demands among any combination of carrier Ethernet switching, WDM and TDM transport technologies with a simple point and click. This ensures that service providers never run into scalability or technology issues, in whatever direction the traffic grows.

Service providers no longer need to debate which transport technology is the most appropriate to deliver their current or future service mix. The Alcatel 1850 TSS offers all of them.

2.2 Product overview

Alcatel-Lucent DWDM Solution – 1830PSS

The Alcatel-Lucent 1830 Photonic Service Switch (PSS) product family is a next generation Metro or Regional Tuneable ROADM platform which enables enhanced flexibility, performance and integration to give full automation of the photonic layer through the use of “Zero Touch Photonics”. The use of the 1830PSS transforms the transport network to enable true networking to simplify and accelerate operations. The 1830PSS-32 is a dense and modular design which can be provisioned as Fixed OADM, Reconfigurable OADM or Tuneable ROADM and allows a Pay as You Grow strategy to deploy services in the most cost effective manner. The carrier class equipment offers full protection of key infrastructure as well a range of network protections to provide an optical networking device capable of delivering the most stringent of SLAs.

Network Design


The fully tuneable architecture of the ROADM units together with the universal transponders means that new services can be set up in minutes rather than hours, days or even weeks, as they do now with traditional methods of transport. A compact range of universal multi-service cards and muxponders allow any new service requirement to use one of only a few types of card which means that spare holdings are drastically reduced. Automation of the whole DWDM network layer is possible though the use of the Wavelength Tracker (WT). The WT is a key tool in the automation process, delivering unrivalled OAM functionality and enabling the NMS operator to see the real time power levels of each wavelength at every key point within the network. This information is key to rapid fault discovery as well for monitoring by the other tools that enable Zero Touch Photonics to continually ensure that the whole network is operating at its optimum level. The WT is also an enabler of the use of alien wavelengths which are monitored in the same manner as a native channel, so that even lambdas originating in another network element outside of the WDM layer can be managed.

Alcatel-Lucent Transport Service Switch – 1850TSS320

The 1850 TSS-320 equipment belongs to the “Alcatel-Lucent New Transport Service Switch family” with the “Universal Matrix Switching” concept.

The whole UNIVERSAL MATRIX capacity can be freely partitioned between TDM and packet traffic (from 100% TDM and 0% packets to 0% TDM and 100% packets) with "slot" granularity. This is possibly thanks to the following key architectural concepts:

Payload matrix or matrices are not performing traffic processing but just cross connection

Traffic processing inside a layer is performed on Port Cards specific to that layer and directly connected to the portion of the UNIVERSAL MATRIX belonging to the layer

Optional Packet Cards or Plug-In Modules are used to interconnect different layers (matrices) either integrated or external to the UNIVERSAL MATRIX: in these cards are put the termination and adaptation functions required by a layered approach.

In this way the signal processing associated to different network layers is distributed among different boards; therefore the system cost and configuration can smoothly scale according to the traffic mix and network layers actually needed being

The major system complexity left in port cards (working inside a layer) and adapter cards or modules (working between different layers)

The system capacity directly proportional to the port cards and adapter cards actually equipped

The overall matrix capacity shared among different layers and the amount of bandwidth per layer dynamically changed on "slot" basis

1850 TSS-320 node Main characteristics are: 320G Electrical "payload agnostic" matrix device able to switch SDH HO VCs, LO VCs,

and packets

Network Design


16 traffic slots to house the line cards with 20Gbps back-panel throughput on each

Each slot can be seen as a couple of half-slot with 10Gbps back-panel throughput, so that the 1850TSS-320 can be considered as a 32 Half-Slots box of 320Gbps total capacity

Multi-Service integration (SDH/Sonet, Data and CWDM)

• SDH/Sonet ports performing the payload processing functions; optical access on the front face of the port cards, electrical accesses provided on a dedicated access panel;

SDH/SONET ports type:

- STM-64/OC-192

- STM-16/OC-48

- STM-4/OC-12 or STM-1/OC-3

• CWDM is provided

• Data processing and switching split among dedicated ports (carrying also Ethernet accesses) with L2 termination, packet classification, buffering, encapsulation and scheduling and the centralized matrix, respectively;

Data ports type:

- Fast Ethernet

- Gigabit Ethernet

- 10 Gigabit Ethernet

EPS protection is foreseen for common parts (i.e. Controllers and Matrices) and for some specific I/O ports (i.e. SDH, Data) to meet levels of reliability required for carrier class deployments

In addition, 1850 TSS-320 is a fully redundant box composed by:

- 1+1 Protected Power Supply

- 1+1 Protected FANs

- 1+1 Protected Controller

- 1+1 Protected Universal Switching Matrix

OMSN (Optical Multiservice Node) –1662SMC Alcatel-Lucent’s OMSN provide world-class, next-generation SDH functionality and capacity through aggregation of broadband multi-protocol traffic patterns. Designed for both metro and core applications, the OMSN product family offers telecom carriers and service providers a powerful solution for building intelligent optical networks and achieving the optimal balance between new competitive service offerings and traditional revenue-generating services. As a member of the OMSN family, the 1662SMC is a compact multiservice provisioning platform at 2.5 that builds next-generation SDH metro transport networks. The 1662SMC provides a single-shelf solution that integrates high-class transport functions- SDH cross connect and CWDM add / drop functionality – together with carrier class Layer 2 packet / cell switching functions – Ethernet, MPLS, and ATM – to support new broadband services such as triple play and video distribution, Ethernet virtual private network (VPN), and 3G mobile aggregation services. In this proposal, 1662SMC is adopted as the drop shelf of TSS-320/160 for E3 / D3 interfaces.

3.2.5 Service Protection Respecting to VTN’s requirement in the specification documentation and the clarification paper about the service protection, the following protecting schemes are proposed:

- 1+1 interface is equipped for STM-64, 10GbE, STM-16, STM-4/1;

- 1+N interface is equipped for E3/D3;

- Working lambda and protection lambda along the different direction are allocated for each traffic channel as the channeling plan in the previous section;

- The protection switch will be operated on the connected client equipment

3.2.6 Channel mapping plan

The 600G DWDM Metro Ring required all types of traffic interface including of STM 64, 10 GBE, GE, STM-16, STM-4, STM-1, E3/DS3. The DWDM layer uses the 40GBit/s per wavelength technology, which means all traffic shall be grooming to 40GBit/s before push to DWDM system. For SDH layer now support for grooming up o STM-64, so VTN Ha Noi Metro link traffic are groomed by two stages:

For E3/DS3 interface: this traffic shall be groomed to STM 16 aggregation.

All traffic from STM-1, STM-4 and STM-16 shall be groomed to STM-64 by SDH equipment by the principle: 4xSTM-16, 2xSTM 16 and 32xSTM-1…

Channel mapping on DWDM Metro Link is presented below.

This MUX (4x10G) tunable transponder card shall map a 40 Gbit/s channel to a lambda on the DWDM layer. Channels shall be mapped to TMUX card on all nodes as per table 3.1.

V. Network Management System

5.1 NMS overview 1350 OMS R9.1 is the Network Management System for the Optical Alcatel-Lucent network, providing an integrated solution for all NEs of the portfolio, encompassing former Lucent, former Alcatel and upcoming Alcatel-Lucent NEs.

1350 OMS architecture has a strong concept of modular SW components. Each component is specialized in a well-defined task. Components can be independently plugged on the 1350 OMS as long as the Customer requires that task to be managed.

Figure 5.1 1350 OMS architecture The chosen system architecture (derived from former Alcatel solution) has been selected because it was deemed to provide the following advantages:

Components deal with well-defined tasks. This allows the specialization of the component both functionally and also from the perspective of their data models to obtain better effectiveness and coherence of the management in the involved area.

Components can evolve independently of each other. The separation of technology DBs and well-defined internal interfaces allow replacing one component by leaving the other unchanged. This has a number of positive effects:

- Simpler patch management: only the impacted SW component needs to be validated by dedicated/deep testing.

- Smooth and easy introduction of new features as only affected components (usually only one) need to be upgraded thus reducing the validation time of the target management solution.

- Improved time to market (faster introduction of new services in field) thanks to the fact that only affected components are to be modified.

Network Design


Components are licensed separately, customers can tailor the NM solution according to their specific needs and pay for the technologies they manage and the additional features of interest

Better scalability can be achieved by an internal structure based on Components. In fact the NMS can scale from being based on a single server only, where all components run on it, to a distributed solution containing a number of servers, (e.g. one per application, or any combination in between). Additionally, to support network growth the NM solution can be evolved from a compact solution (all components in one server) to a distributed one. This will happen with no changes on look&feel or operability.

Components interact with each other in order to provide an integrated Network Management system solution (e.g. cross-layer fault location, cross-layer service set-up, …)

All components are integrated with the same Graphical User Interface (GUI), so that Operators work with the same look&feel on all of them with no specific GUI training being required when moving from one technology area to another one.

1350 OMS R9.1 is composed of two kinds of items: the Core modules - herewith listed – which provide the normal, day-by-day FCAPS management capabilities required of NM systems; and the Added Value modules which refer to product options covering more specific and sophisticated management areas.

1350 OMS-EML It provides the Element Management functionality of the 1350 OMS product. It manages the full set of converged NEs (see chapter on supported NEs), providing integrated, coherent and homogeneous NE supervision and administration capabilities.

1350 OMS-SDH It provides end-to-end control of SDH services over the network, including former Alcatel and former Lucent NEs. It exploits mediation functions provided by 1350 OMS-eOMS to control the legacy former Lucent network on a per subnetwork management basis. In addition to pure SDH management, it provides WDM management services over the former Alcatel WDM NEs, and provides mediation capabilities to 1350 OMS-WDM component.

1350 OMS-SONET It provides end-to-end control of SONET services over the network, including some former Alcatel and former Lucent NEs.

1350 OMS-WDM It provides end-to-end control of WDM services over the network, including former Alcatel and some former Lucent NEs. It exploits mediation functions provided by

Network Design


1350 OMS-SDH to control the legacy former Alcatel network on a per subnetwork management basis. It interworks with photonic planning tools to import results of planning analysis as well as to optimize optical tuning optimization.

1350 OMS-PKT It provides end-to-end control of Ethernet and T-MPLS services over the network, including former Alcatel and former Lucent NEs. It exploits mediation functions provided by 1350 OMS-eOMS to control the legacy former Lucent network on a per subnetwork management basis.

1350 OMS-eOMS It provides end-to-end control of SDH, Ethernet and WDM services over the former Lucent network domains. It offers mediation functions to the other 1350 OMS NML components so that they can achieve in the technology of interest the comprehensive supervision of the overall network. It is worth noting here that 1350 OMS-eOMS is the OMS Network Management system instance working within 1350 OMS product. It provides the original OMS GUI to guarantee continuity on Customers operations over the existing, deployed, former Lucent networks.

1350 OMS-HA It provides High Availability capabilities over all components. It is EML/NML technology independent: a single set of design principles enables a single operational approach and the same resilience features over the different components.

1350 OMS-OI It is the generic name for the whole set of open interfaces that 1350 OMS product provides. In includes former Alcatel, former Lucent and long term converged interfaces.

In addition to the above Core applications, 1350 OMS provides a number of added-value components that provide a comprehensive, full featured and unrivalled NMS portfolio:

1350 OMS-VPN It is Customer Network Management, or Virtual Private Network, solution that allows Network Providers to grant a fully controlled access, read-only or read-write, to VIP end-users. End users can, according to assigned profile, see alarms of their circuits/services, PM data for SLA check, or even configure services according to contract.

1350 OMS-DCN It is the monitoring application that allows controlling the Data Communication Network relying the NMS to the NEs, both in-fiber and out-of-fiber. It provides non-intrusive monitoring of IS-IS and OSPF protocols, so it is inherently a multi-vendor

Network Design


product that can apply in any DCN where the installed elements comply with the mentioned dynamic routing protocol standards.

1350 OMS-SY It allows controlling the Synchronization Distribution Network within the Transport network. It works on former Alcatel NEs as well as on converged NEs.

5.2 DCN network solution

The Optical and/or Broadband Access Network can be divided into two networks: the traffic network and Data Communication Network (DCN). The traffic network handles the transmission of the user data between stations. The DCN is not only composed of the network between the Management System and the gateway NE’s but also the transport between NE’s using either in-band or out-of band communication channels.

The management system architecture to manage equipments of DWDM 600G Metro Link Ha Noi is suggested as the diagram below:

Figure 5.2.1 The DCN network solution

Regarding network DCN in each NOC the solution is to have 2 GNE, 1GNE x TSS320 and 1GNE x1830PSS as will have two different protocols IS-IS for TSS equipment respectively IP/SNMP for PSS equipment. The proposed NMS will be connected through a multiprotocol switch with the 2GNE, as NMS and GNE are located in the same NOC.

VI. Network Synchronization

A ring accepts timing from a Primary Injection Point (PIP) and may deliver timing to other Sub network via any NE. The ring is configured to be resilient to: failure of timing delivery to the PIP; single faults within the ring; double faults which fragment the ring where each fragment is connected to either the SIP or the PIP. Under such fault conditions the elements will autonomously recover timing, traceable to the SIP or PIP, with SSMB quality marker set to that of the source input.

6.1 Synchronization Design for DWDM layer

In DWDM 600G Metro Link Ha Noi project, 1830 PSS is not required synchronization signal for their operation. 1830 PSS shall transmit the clock signal in STM-n transparently through WDM layer.

6.2 Synchronization Design for SDH layer

All SDH NEs require timing in order to generate the necessary synchronization and frame phase reference information. The timing can be provided by a source external to the NE or an internal timing generator. The derived timing shall be used for all signals and interfaces in the NE that are related to the SDH frame structure.

Follows a brief description of the heart of the NE clock known as the Synchronization Equipment Timing Source (SETS).

It can be divided into 2 parts:

OSC: the internal oscillator.

Network Design


SETG: the Synchronization Equipment Timing Generator.

The SETG is responsible for the generation of the external timing source for the Frame structure and the clock, whilst the internal oscillator (OSC) is useful only in the abnormal functioning "Free-running" mode that will be explained later.

The simplified figure that follows represents the internal organization of the SETS.

Figure 6.2 Internal organization of SETS

The internal sources (inputs) are: T1: Reference obtained from incoming STM-N signals,

T2: Reference obtained from incoming 2 Mbits signals (not available in current

release),

T3/T6: Reference obtained from an external incoming 2.048 MHz (T3) or 2.048 Mbit/s

(T6) signal.

OSC: the internal oscillator.

The number of timing reference inputs depends on the configuration of the NE. The external sources (outputs) are:

T0: is the reference output signal for the clock and signal frames,

T4: is the 2 MHz reference output for the external equipment synchronization.

T5: is the 2 Mbit/s reference output for the external equipment synchronization.

Other reference points: Y: is used for communication of Synchronization Status Message (SSM) between

SETS and MST functional blocks.

S15: is used to provide notifications and loss of incoming timing reference reporting to the Synchronous Equipment Management Function (SEMF).

Network Design


Selector A provides the capability to select timing reference from available T1 inputs, either automatically based on the priority and quality level of the candidate sources (SSM algorithm), or manual as a result of commands issued from the managing system.

Selector B is capable of selecting timing reference from T1, T2, or T3/T6 inputs, according to the SSM algorithm. The capability for manual selection of the timing source is also provided.

Selector C is only operated in manual mode, to switch between SETG output signal (T0) and a T1 timing reference.

The squelch functions A and B mute the relevant timing references in the presence of failure condition, or SSM threshold violation.

The choice of the timing reference is done in two ways:

Automatically: Following a particular algorithm based on the quality and the priority of the incoming timing signals. The automatic selection is based either on the priority of the incoming timing source (Priority algorithm) or on the priority and the quality level of the incoming sources (SSM algorithm).

Manually: Following an order from the Operator.

N.B. The priority level is determined by the Operator for each candidate timing source. It is static information. On the other hand, the quality of the source is dynamic information, dependant of the quality of the reference clock generating the timing.

In an SDH signal frame, the quality of the timing source is located in the Section Overhead.

The SETG has 3 modes of operation: Locked mode:

The SETG output is fully controlled by the external timing references (T1, T2 and T3/T6).

Hold-Over mode:

The external timing reference is malfunctioning. The SETG during normal functioning stores regularly the value of the external timing reference. In this case the SETG output is controlled by this memorized value.

Free running mode:

This is not a normal operating mode. The external timing reference and the memorized timing reference are malfunctioning. In this case the SETG output is controlled by the internal clock source.

6.2.1 Synchronization distribution plan

With the DWDM 600G Metro Link Ha Noi project, only primary Reference Clock (PRC) is distributed in site of VTN-C2. This clock after that shall be distributed to all NE of the Ring on the SDH traffic over two directions. One direction is working and another one is standby. In the case, Primary reference clock lost, NE shall use their internal clock which can provide to free run using the internal +/- 20ppm internal oscillator of the unit.

Network Design


The master 1850 TSS shelf at site of VTN-C2 will receive two external clocks T3 or T6 with the same accuracy level from two port EXT 1 and EXT 2. The third priority will receive from internal oscillator OSC with free run. Remain shelves of VTN-C2 will receive clock signal from clock signal output of master shelf. The clock distributed for VTN-C2 are presented in the figure below.

Figure 6.2.1.1 Clock Plan at VTN-C2 Node

For other sites in Ring, 1850 TSS family will receive clock from STM 64 aggregation which directly come from VTN-C2 with first priority is the working direction, the second priority will be the protection direction. The third priority will use internal oscillator.

With the 1662 SMC family will receive clock from STM 16 with first priority from STM-16 working interface, second priority from STM-16 protection interface. Third priority shall use the internal oscillator.

The clock distributed for all sites on network are presented in the figure below.

6.2.2 Clock protection plan

The VTN-C2 receive primary Reference Clock (PCR) from the external resource then distribute clock signal to all NE on network over two directions, one working and one for standby. The clock on working direction is first priority, the standby direction is second priority. In the normally condition, All NE of network reference the first priority clock. If the ring are broken, NE will receive clock from the standby direction with the second priority. In case, the PCR lost, or the ring broken both directions, NE will receive clock from internal oscillator. Clock distribution plan and its priority are presented in table below:
