Abstract:
A method of Path Computation Element (PCE) Communication Protocol (PCEP) communication includes sending, to a path computation element (PCE), a request to compute a backup ingress node for a Point-to-Multipoint (P2MP) Label Switched Path (LSP) in a network, and receiving, from the PCE, the backup ingress node for the P2MP LSP in accordance with the request.
