Patent ID: 8861342

Claim:
A method comprising: receiving data packets of a video data stream, at an aggregation node from one or more source nodes, via both a primary point-to-multipoint path and a secondary point-to-multipoint path simultaneously over a network; wherein transport nodes of the primary point-to-multipoint path and the secondary point-to-multipoint path have no common points of physical topology other than the aggregation node; wherein the primary point-to-multipoint path and the secondary point-to-multipoint path are over label-switched paths; forwarding data packets of the video data stream, received via the primary point-to-multipoint path, over the network to an access node; after forwarding the data packets received via the primary point-to-multipoint path, the aggregation node detecting a failure on the primary point-to-multipoint path; in response to detecting the failure, the aggregation node forwarding data packets of the video data stream received via the secondary point-to-multipoint path to the access node.
