Title: METHOD AND APPARATUS FOR DYNAMIC SERVICE CHAINING WITH SEGMENT ROUTING FOR BNG
Abstract:
A method is performed by a network device functioning as a Broadband Network Gateway (BNG) to enable dynamic service chaining for subscribers. The method includes receiving a first sign of life packet from a subscriber device associated with a subscriber, transmitting, to an authentication, authorization, and accounting (AAA) server, a request to authenticate the subscriber in response to receiving the first sign of life packet from the subscriber device associated with the subscriber, receiving information pertaining to a service chain associated with the subscriber upon successful authentication of the subscriber by the AAA server, generating a routing header to be added to packets belonging to the subscriber based on the information pertaining to the service chain associated with the subscriber, where the routing header includes an indication of the service chain associated with the subscriber.
