Abstract
Disclosed is an apparatus that includes a path computation element (PCE) configured to communicate with a path computation client (PCC) and compute a backup ingress node for a Point-to-Multipoint (P2MP) Label Switched Path (LSP) in a network associated with the PCC. The backup ingress node is coupled to an ingress node of the P2MP LSP and to a plurality of next-hop nodes of the ingress node of the P2MP LSP via a backup tree.
