Problems solved by technology

The cost of a centralized solution is high as it does not reduce complexity and tends to produce a vertical solution as the servers providing the solution are provided on a per service basis

Embodiment Construction

[0018] refer to figure 1 , shows an example of the telecom 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 18 of the domain. The network elements of the domain are interconnected by communication links 16 in various ways. figure 1 The fields shown are for example only. More generally, the domain includes a plurality of network elements, at least two of which are border gateways. These border gateways provide communication access to devices outside the domain, such as border gateways of other domains, or end-user devices.

[0019] The domain also includes the management layer 20 . The management layer 20 includes multiple components, including a service request manager, a service domain manager, a common naming service, a signali...

Abstract

Apparatus and method are provided for enabling establishment of cross-domain services, including exchange of reachability information between domains, routing of services across domains, and differential labeling. The network element control and management planes are supplemented by additional components that enable the control and management planes of each domain to inter-communicate in a peer-to-peer manner. Adjacencies are established between domains, and service reachability information is exchanged between domains. Network Service Applications within the management planes can then establish services across the domains by inter-communicating.

Description

[0001] Cross-references to other applications [0002] This application claims priority to Canadian Patent Application No. 2,467,939, filed May 20, 2004, entitled "Structure for Configuration and Management of Cross-Domain Network Services." technical field [0003] The present invention relates to the management and provision of telecommunication networks, and more particularly, to the provision of end-to-end network services in multi-domain networks. Background technique [0004] Many emerging communication network services require the interworking of several management domains, such as IP- and Ethernet-based virtual private networks (VPNs) that span domains of multiple service providers. The configuration and operation of these cross-domain services (whether cross-management, technical or multi-vendor network equipment) requires the exchange of business information between disparate systems. Since different domains handle provisioning issues in different ways (eg address...
