Pre-standard Linear Protection Switching in MPLS Transport Profile
RFC 7347, “Pre-standard Linear Protection Switching in MPLS Transport Profile”, is an Informational document published in September 2014 by H. van Helvoort, J. Ryoo, H. Zhang, F. Huang, H. Li, A. D'Alessandro. The canonical text is published by the RFC Editor.
Abstract
The IETF Standards Track solution for MPLS Transport Profile (MPLS-TP) Linear Protection is provided in RFCs 6378, 7271, and 7324.
This document describes the pre-standard implementation of MPLS-TP Linear Protection that has been deployed by several network operators using equipment from multiple vendors. At the time of publication, these pre-standard implementations were still in operation carrying live traffic.
The specified mechanism supports 1+1 unidirectional/bidirectional protection switching and 1:1 bidirectional protection switching. It is purely supported by the MPLS-TP data plane and can work without any control plane.
What “Informational” means
Published for the general information of the community. It does not define an IETF standard and carries no standards-track status.
