METHOD AND APPARATUS FOR SERVICE PROVISION IN A COMMUNICATION NETWORK

Abstract:

A method (100) for managing the provision of a service between origin and destination endpoints over a communication network is disclosed. The communication network comprises at least two Autonomous Systems (ASs) and an Abstraction and Control of Traffic Engineered Networks Virtual Network (VN) between the origin and destination endpoints. The method comprises defining, at each of the origin and destination endpoints, a service segregation loopback interface corresponding to a subset of traffic belonging to the service (110). The method further comprises binding the subset of traffic to the VN by exposing the service segregation loopback interface defined at the destination endpoint as routing next hop only to traffic belonging to the subset (120).
