RSVP-TE Signaling Procedure for End-to-End GMPLS Restoration and Resource Sharing

Abstract

In non-packet transport networks,

Updates to the Fast Reroute Procedures for Co-routed Associated Bidirectional Label Switched Paths (LSPs)

“…In packet transport networks, a restoration LSP is signaled after a link failure on the protected LSP path and the protected LSP may or may not be torn down [RFC8131]. In this case, multiple forward and reverse LSPs of a co-routed associated bidirectional LSP may be present at mid-point nodes with identical (Extended) ASSOCIATION Objects.…”
