Embodiment Construction

[0017] Referring to Figure 1, this figure shows an example of the telecommunications domain. The domain includes a first border gateway 10 , a second border gateway 12 and a plurality of internal network elements 14 . Collectively, the first border gateway 10, the second border gateway 12 and the plurality of internal network elements 14 are referred to as network elements of the domain. The network elements of the domain are variously interconnected via communication links 16 . The domains shown in Figure 1 are for example purposes only. More generally, the domain includes a plurality of network elements, at least two of which are border gateways. Border gateways provide communication access to devices outside the domain, such as border gateways or end-user devices of other domains.

[0018] The domain also includes the management layer 20 . The management layer 20 comprises a number of components including a Service Domain Manager (SDM). The SDM preferably takes the for...

Abstract

Apparatus and method are provided for distributing service domain reachability information across domain boundaries, thereby allowing domain management systems to determine routing for cross-domain services even when the domains have different technologies or administrators. A Service Domain Manager within each domain advertises to neighbouring domains which services it supports. A domain which receives such advertisements forwards the advertisement on to other domains. Each SDM builds a routing information table which specifies the service, the domain, the next hop, and optionally user defined metrics. The routing information table does not include end-point addresses, in order to keep the size of the table manageable. In this way, the NMS of each domain obtains an end-to-end view of service routes.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Canadian Patent Application 2,467,945, filed May 20, 2004, and entitled "Open Service Discovery and Routing Mechanism for Configuring Cross-Domain Telecommunications Services." technical field [0003] The present invention relates to routing within a telecommunications network, and more particularly to the exchange of reachability information within a multi-domain network. Background technique [0004] The configuration and operation of cross-domain services is an important issue for networks and network service providers. As service providers establish peer-to-peer and large-scale relationships with multiple service provider partners, they find themselves in the complex situation of having to span a range of disparate and non-integrated and specific technology management systems to deploy services. The problem of cross-domain service management, whether it means coordinating ma...
