TOPOLOGY DISCOVERY, CONTROL CHANNEL ESTABLISHMENT, AND DATAPATH PROVISIONING WITHIN AN AGGREGATION NETWORK WITH CENTRALIZED CONTROL

摘要

An access network is described in which a centralized controller provides seamless end-to-end service from a core-facing edge of a service provider network through aggregation and access infrastructure out to access nodes located proximate to the subscriber devices. The controller operates to provide a central configuration point for configuring aggregation nodes (AGs) of a network of the service provider so as to provide transport services to transport traffic between access nodes (AXs) and edge routers on opposite borders of the network.
