The IESG has approved the following document: - 'Dual-Homing Protection for MPLS and MPLS-TP Pseudowires' (draft-ietf-pals-mpls-tp-dual-homing-protection-06.txt) as Informational RFC 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-protection/ Technical Summary This document describes a framework and several scenarios for a Pseudowire (PW) dual-homing local protection mechanism which avoids unnecessary switchovers and which can be used for scenarios using a control plane or not using a control plane. A Dual-Node Interconnection (DNI) PW is used for carrying traffic between the dual-homing Provider Edge (PE) nodes for carrying traffic when a failure occurs in one of the Attachment Circuits (AC) or PWs. This PW dual-homing local protection mechanism is complementary to existing PW protection mechanisms. Working Group Summary This was a straight-forward design process with no controversy. The AD discussed with the Chairs and Authors to combine this document with the companion standards track document, the preference was to do as two separate documents. There was some shuffling on the content, e.g. the state diagram was moved to the standards track document. 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.
