BNG / SUBSCRIBER MANAGEMENT INTEGRATED, FIB BASED, PER SUBSCRIBER, OPT-IN OPT-OUT, MULTI APPLICATION SERVICE CHAINING SOLUTION VIA SUBSCRIBER SERVICE CHAINING NEXTHOP AND META IP LOOKUP

摘要

Exemplary methods for performing service chaining include generating a plurality of service chaining (SC) next hops (NHs) by, for each SC NH hop, generating a plurality of SC maps, each SC map identifying a chain of one or more service modules, wherein each service module is to apply a corresponding service on a packet. The methods further include generating a plurality of hosted NHs, each hosted NH including forwarding information that causes the packet to be forwarded to a corresponding service module. The methods further include in response to receiving a first packet, identifying a SC NH of the plurality of SC NHs based on an Internet Protocol (IP) address of the first packet, and forwarding the first packet to a service module based on the identified SC NH.

1. A method in a first network device for performing service chaining, the method comprising:
generating a plurality of service chaining (SC) next hops (NHs) by, for each SC NH hop:
generating a plurality of SC maps, each SC map identifying a chain of one or more service modules, wherein each service module is to apply a corresponding service on a packet, andgenerating a plurality of hosted NHs, each hosted NH including forwarding information that causes the packet to be forwarded to a corresponding service module; in response to receiving a first packet, identifying a SC NH of the plurality of SC NHs based on an Internet Protocol (IP) address of the first packet; and forwarding the first packet to a service module based on the identified SC NH.
