1.2 Network Manager: Introduction 1.2.1 Network Management System Overview

The Network Management System (NMS) forms a flexible platform that is used to manage Digital Telecommunication Networks consisting of SDH and WDM equipment.




The system architecture of the NMS can be sized to meet the needs of the customer's organization in terms of: type of Network Elements (NEs), size of the Managed Network and the required management functions. In terms of functional architecture according to the ITU-T Recommendation M.3010, the NMS covers the Element Management Layer (EML), Network Management Layer (NML) and partially the Service and Business Management Layers (SML and BML). The system consists of: Commercial hardware and software platforms; A Software package that can be configured in a modular way to fit the

management requirements of networks of various sizes and configurations. The EM product covers the EML functions. The NM product relies on the services offered by the EM to provide NML functions. Partial SML and BML functions are provided to deal with customer requests, to provide special services and to maintain customer administration. The EM and NM can be configured to address various scenarios.

The NMS covers the functional areas of Fault, Configuration, Performance and Security Management in line with ITU-T Recommendation M.3400. The NMS hardware platform is based on servers and workstations connected via a Data Communication Network (DCN). A small SDH network can be managed by a single computer platform, while large networks require multiple computer configurations, where each computer, server or workstation, is dedicated to specialised functions, in order to share the total processing and communication load. Routers connected with dedicated lines provide remote access to the servers and from the servers to the NE. To increase the NMS reliability, duplicated platforms can be used.




1.2.2 Network and Service Manager Functionalities The purposes of the NM are: Management of sub networks on a network basis, that is, the topology of the

network defined at the lowest level in terms of NEs and links (physical compositions);

Management of the functional aspects of the network (connections, ports and other resources).

The resources on which these functions apply are: Connection Points (CP); Subnetworks (SN); Links; Paths. The NM accesses the SDH/WDM NEs by interfacing to one or more Element Managers. The EMs share their databases with the NM by passing it information about the connection points (SDH ports), giving it access to the alarm and performance monitoring available in the network. It is possible to associate NEs together to form subnetworks. The Connection Points (CPs) are used to define links between Network Elements. Each link can be configured to carry different SDH paths (VC-12, VC-2, VC-3, VC-4) depending on the configuration of the network.

EM

The Service and Business Management layer provides, among its functions, the ability to manage the network from a users point of view. This layer recognizes the user ports, but it is not aware of the structure of the network. The resources up on which these functions apply are: Termination points; Circuits.




TPs are all the user access ports (PDH or SDH) and TUs available in the network. The circuit is a connection between two termination points using the transport resources available. The available circuit types are 2Mbit/s, 34Mbit/s, 45Mbit/s and 140Mbit/s and their relevant concatenation levels.




1.3 Management of WDM Equipment 1.3.1 Introduction to WDM Management

The management of the SDH network performed by ServiceOn Optical Management System is based on a logical model supplied within the application software. According to this model, the network resources are defined as functional objects through which it is possible to operate and control the traffic flowing through the nodes. The above-mentioned network resources are formed by accurate relationships among parameters, which belong specifically to NEs (Line Cards, Tributary ports, Cross-Connections). These relationships are created within the NM database and then used to drive the different NEs so as they can be configured with the correct configuration necessary for the traffic to be routed correctly.

The functional objects defined in the logical model are: Internodal Link: the combination of two Line Cards equipped on different NEs,

connected via optical fibre or other media. Circuit: the combination of some cross-connections (terminal, passing through)

equipped on different NEs and joined by means of internodal links. VC-4 Path: the combination of internodal links or some channel inside them,

which display the same frame structure.

1.3.2 Operating Roles of the SDH Network Resources In order to correctly represent the functional objects (network resources), all the equipment parameters must be associated to an operating role: The SDH cards (STM-1, STM-4, STM16, etc.) are presented as line resources The TUs in a structured SDH interfaces are presented as termination points The input and the output ports (2Mb/s, 34Mb/s, etc.) available on NEs are always

presented as tributary resources




Cross connections are defined as removable items that physically join one tributary and one line resource or even two different line resources

In the SDH network, a cross connection respond to specific real commands that carry out effective configuration in the switch cards of NEs. LCT, EM and ServiceOn OMS can set these commands.

1.3.3 Operating Roles of the WDW Network Resources With the aim of applying the SDH logical model to Photonics NEs, some new network resources have been added. These new templates are necessary to correctly combine the specific WDM parameters into a proper network relation. According to this need, different WDM NE parameters have been associated to the usual operating roles already defined in the standard NM logical model: The WDM cards (mux+demux) are presented as line resources. Fixed transponders and OIC (Optical Interconnect Cards) are presented as

tributary resources. The association between one channel of WDM card and a specific lambda

(wavelength), supported by a transponder card is presented as a cross connection.

1.3.3.1 Optical Cross Connections About the "optical cross connection" definition, important notes must be taken into account: Optical Cross connections are an abstraction, since there is no active matrix card

on WDM equipment. The matching between wavelengths and WDM channels are dependent on the

cards position in the subrack. Exactly like in a line terminal, modification is not allowed via software (LCT, EM or

NM), but a hardware action is necessary. This is the reason why the NM cannot create or remove optical cross connections

but only it can adopt them from the NE HW configuration.
