Updates to the Resource Reservation Protocol for Fast Reroute of Traffic Engineering GMPLS Label Switched Paths
RFC 8271, “Updates to the Resource Reservation Protocol for Fast Reroute of Traffic Engineering GMPLS Label Switched Paths”, is a Proposed Standard document published in October 2017 by M. Taillon, T. Saad, R. Gandhi, Z. Ali, M. Bhatia. It updates RFC 4090. The canonical text is published by the RFC Editor.
Abstract
This document updates the Resource Reservation Protocol - Traffic Engineering (RSVP-TE) Fast Reroute (FRR) procedures defined in RFC 4090 to support Packet Switch Capable (PSC) Generalized Multiprotocol Label Switching (GMPLS) Label Switched Paths (LSPs). These updates allow the coordination of a bidirectional bypass tunnel assignment protecting a common facility in both forward and reverse directions of a co-routed bidirectional LSP. In addition, these updates enable the redirection of bidirectional traffic onto bypass tunnels that ensure the co-routing of data paths in the forward and reverse directions after FRR and avoid RSVP soft-state timeout in the control plane.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
