The IESG has approved the following document: - 'Dual-Homing Coordination for MPLS Transport Profile (MPLS-TP) Pseudowires Protection' (draft-ietf-pals-mpls-tp-dual-homing-coordination-06.txt) as Proposed Standard This document is the product of the Pseudowire And LDP-enabled Services Working Group. The IESG contact persons are Alvaro Retana, Alia Atlas and Deborah Brungard. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-pals-mpls-tp-dual-homing-coordination/ Technical Summary In some scenarios, MPLS Transport Profile (MPLS-TP) Pseudowires (PWs) (RFC 5921) may be statically configured (management plane based), 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 [draft-ietf-pals-mpls-tp-dual-homing-protection]. This document proposes a dual-homing coordination mechanism for MPLS-TP PWs, which is used for state exchange and switchover coordination between the dual-homing PEs for dual-homing PW local protection. Working Group Summary This was a straight-forward design process with no controversy. The AD did discuss with the Chairs and Authors on combining this document and the companion Informational document, though the preference was to maintain two documents. Document Quality Dual homed protection is important for mobile services, and the need for this is called out in BBF TR-221 " Technical Specifications for MPLS in Mobile Backhaul Networks" where it remains for further study.
