Dual-Homing Coordination for MPLS Transport Profile Pseudowires Protection
RFC 8185, “Dual-Homing Coordination for MPLS Transport Profile Pseudowires Protection”, is a Proposed Standard document published in June 2017 by W. Cheng, L. Wang, H. Li, J. Dong, A. D'Alessandro. The canonical text is published by the RFC Editor.
Abstract
In some scenarios, MPLS Transport Profile (MPLS-TP) pseudowires (PWs) (RFC 5921) may be statically configured when a dynamic control plane is not available. A fast protection mechanism for MPLS-TP PWs is needed to protect against the failure of an Attachment Circuit (AC), the failure of a Provider Edge (PE), or a failure in the Packet Switched Network (PSN). The framework and typical scenarios of dual- homing PW local protection are described in RFC 8184. This document proposes a dual-homing coordination mechanism for MPLS-TP PWs that is used for state exchange and switchover coordination between the dual- homing PEs for dual-homing PW local protection.
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.
