RFC 7271 Title: MPLS Transport Profile (MPLS-TP) Linear Protection to Match the Operational Expectations of Synchronous Digital Hierarchy, Optical Transport Network, and Ethernet Transport Network Operators Author: J. Ryoo, Ed., E. Gray, Ed., H. van Helvoort, A. D'Alessandro, T. Cheung, E. Osborne Status: Standards Track Stream: IETF Date: June 2014 Mailbox: ryoo@etri.re.kr, eric.gray@ericsson.com, huub.van.helvoort@huawei.com, alessandro.dalessandro@telecomitalia.it, cts@etri.re.kr, eric.osborne@notcom.com Pages: 40 Characters: 87586 Updates: RFC 6378 I-D Tag: draft-ietf-mpls-tp-psc-itu-04.txt URL: http://www.rfc-editor.org/rfc/rfc7271.txt 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. This document is a product of the Multiprotocol Label Switching Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet standards track protocol for the Internet community,and requests discussion and suggestions for improvements. Please refer to the current edition of the Internet Official Protocol Standards (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.
