The IESG has received a request from the Pseudowire And LDP-enabled Services WG (pals) to consider the following document: - 'S-PE Protection for MPLS and MPLS-TP Static Multi-Segment Pseudowires' <draft-ietf-pals-ms-pw-protection-03.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2015-10-15. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract In MPLS and MPLS-TP environments, statically provisioned Single- Segment Pseudowires (SS-PWs) are protected against tunnel failure via MPLS-level and MPLS-TP-level tunnel protection. With statically provisioned Multi-Segment Pseudowires (MS-PWs), each segment of the MS-PW is likewise protected from tunnel failures via MPLS-level and MPLS-TP-level tunnel protection. However, static MS-PWs are not protected end-to-end against failure of one of the switching PEs (S-PEs) along the path of the MS-PW. This document describes how to achieve this protection via redundant MS-PWs by updating the existing procedures in RFC 6870. It also contains an optional approach based on MPLS-TP Linear Protection. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-pals-ms-pw-protection/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-pals-ms-pw-protection/ballot/ No IPR declarations have been submitted directly on this I-D.
