Abstract
A system comprising a plurality of path computation elements (PCEs) configured to communicate with an ingress node, jointly compute a core tree for an inter-domain point-to-multipoint (P2MP) tree across a plurality of network domains, and independently compute a plurality of sub-trees in at least some of the network domains, wherein the core tree connects the ingress node to a boundary node (BN) in each one of the network domains that have a destination node and each sub-tree connects the BN to a plurality of destination nodes in one of the network domains that have a destination node.
