Abstract:
Subscriber management and network service integration for an access network is described in which a centralized controller provides seamless end-to-end service from a network to access nodes. For example, a method includes dynamically establishing a control channel between the centralized controller and an access node, and establishing a transport label switched path (LSP) transport network packets between the access node and the network node. The access node sends, via the control channel, an endpoint indication message that indicates that an endpoint that has joined the network at the access node. The access node receives a pseudo wire request message via the control channel to install forwarding state for creating a pseudo wire for providing one or more network services to the endpoint. The access node receives a direct switch message via the control channel to configure the access node to map traffic received from the endpoint to the pseudo wire.
