Dear PALS WG and chairs, I'd like to inform you about this new revision (-02) of the draft. In this revision, we have addressed all the comments from the LC. Specifically, the sections 4.1, 4.2, 4.3.2, 4.5, and 7 have been updated to particularly address the comments from Steward Bryant and Mach Chen. Thanks again for their detailed review. We believe it has helped us improve the clarify of the document. Regards, /Yimin Shen -----Original Message----- From: internet-drafts@ietf.org [mailto:internet-drafts@ietf.org] Sent: Wednesday, January 27, 2016 10:50 AM To: Yimin Shen; Rahul Aggarwal; Wim Henderickx; Yuanlong Jiang Subject: New Version Notification for draft-ietf-pals-endpoint-fast-protection-02.txt A new version of I-D, draft-ietf-pals-endpoint-fast-protection-02.txt has been successfully submitted by Yimin Shen and posted to the IETF repository. Name: draft-ietf-pals-endpoint-fast-protection Revision: 02 Title: PW Endpoint Fast Failure Protection Document date: 2016-01-27 Group: pals Pages: 31 URL: https://www.ietf.org/internet-drafts/draft-ietf-pals-endpoint-fast-protection-02.txt Status: https://datatracker.ietf.org/doc/draft-ietf-pals-endpoint-fast-protection/ Htmlized: https://tools.ietf.org/html/draft-ietf-pals-endpoint-fast-protection-02 Diff: https://www.ietf.org/rfcdiff?url2=draft-ietf-pals-endpoint-fast-protection-02 Abstract: This document specifies a fast mechanism for protecting pseudowires against egress endpoint failures, including egress attachment circuit failure, egress PE failure, multi-segment PW terminating PE failure, and multi-segment PW switching PE failure. Operating on the basis of multi-homed CE, redundant PWs, upstream label assignment and context specific label switching, the mechanism enables local repair to be performed by the router upstream adjacent to a failure. The router can restore a PW in the order of tens of milliseconds, by rerouting traffic around the failure to a protector through a pre-established bypass tunnel. Therefore, the mechanism can be used to reduce traffic loss before global repair reacts to the failure and the network converges on the topology changes due to the failure. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org. The IETF Secretariat
