RSVP-TE Signaling Procedure for End-to-End GMPLS Restoration and Resource Sharing
RFC 8131, “RSVP-TE Signaling Procedure for End-to-End GMPLS Restoration and Resource Sharing”, is an Informational document published in March 2017 by X. Zhang, H. Zheng, R. Gandhi, Z. Ali, P. Brzozowski. The canonical text is published by the RFC Editor.
Abstract
In non-packet transport networks, there are requirements where the Generalized Multiprotocol Label Switching (GMPLS) end-to-end recovery scheme needs to employ a restoration Label Switched Path (LSP) while keeping resources for the working and/or protecting LSPs reserved in the network after the failure occurs.
This document reviews how the LSP association is to be provided using Resource Reservation Protocol - Traffic Engineering (RSVP-TE) signaling in the context of a GMPLS end-to-end recovery scheme when using restoration LSP where failed LSP is not torn down. In addition, this document discusses resource sharing-based setup and teardown of LSPs as well as LSP reversion procedures. No new signaling extensions are defined by this document, and it is strictly informative in nature.
