Title : MPLS Transport Profile (MPLS-TP) Linear Protection to Match the Operational Expectations of SDH, OTN and Ethernet Transport Network Operators
Author(s) : J. Ryoo, et al
Filename : draft-ietf-mpls-tp-psc-itu
Pages : 37
Date : 2014-02-24
This document describes alternate mechanisms to perform some of the
functions of MPLS Transport Profile (MPLS-TP) linear protection
defined in RFC 6378, and also defines additional mechanisms. The
purpose of these alternate and additional mechanisms is to provide
operator control and experience that more closely models the behavior
of linear protection seen in other transport networks.
This document also introduces capabilities and modes for linear
protection. A capability is an individual behavior, and a mode is a
particular combination of capabilities. Two modes are defined in
this document: Protection State Coordination (PSC) mode and Automatic
Protection Switching (APS) mode.
This document describes the behavior of the PSC protocol including
priority logic and state machine when all the capabilities associated
with the APS mode are enabled.
This document updates RFC 6378 in that the capability advertisement
method defined here is an addition to that document.
