Working Group, There has been quite a bit of changes to this document during AD and RTG Dir review of this document. The changes are editorial, but because of volume it might be a good idea to look at the document a second time. One of the co-authors characterized the the changes like this: "No changes were made to the procedures or packet formats, but a number of text changes were made to improve the language and overall readability. In addition, some of the sections were rearranged to improve the flow." /Loa mpls wg co-chair -------- Forwarded Message -------- Subject: Last Call: <draft-ietf-mpls-entropy-lsp-ping-04.txt> (Label Switched Path (LSP) and Pseudowire (PW) Ping/Trace over MPLS Network using Entropy Labels (EL)) to Proposed Standard Resent-Date: Fri, 12 Aug 2016 08:35:51 -0700 (PDT) Resent-From: alias-bounces@ietf.org Resent-To: swallow.ietf@gmail.com, tsaad@cisco.com, n.leymann@telekom.de, loa@pi.nu Date: Fri, 12 Aug 2016 08:35:51 -0700 From: The IESG <iesg-secretary@ietf.org> Reply-To: ietf@ietf.org To: IETF-Announce <ietf-announce@ietf.org> CC: mpls@ietf.org, draft-ietf-mpls-entropy-lsp-ping@ietf.org, mpls-chairs@ietf.org, db3546@att.com, loa@pi.nu The IESG has received a request from the Multiprotocol Label Switching WG (mpls) to consider the following document: - 'Label Switched Path (LSP) and Pseudowire (PW) Ping/Trace over MPLS Network using Entropy Labels (EL)' <draft-ietf-mpls-entropy-lsp-ping-04.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 2016-08-26. 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 Multiprotocol Label Switching (MPLS) Label Switched Path (LSP) Ping and Traceroute are methods used to test Equal-Cost Multipath (ECMP) paths. Ping is known as a connectivity verification method and Traceroute as a fault isolation method, as described in RFC 4379. When an LSP is signaled using the Entropy Label (EL) described in RFC 6790, the ability for LSP Ping and Traceroute operations to discover and exercise ECMP paths is lost for scenarios where LSRs apply different load balancing techniques. One such scenario is when some LSRs apply EL-based load balancing while other LSRs apply non-EL based load balancing (e.g., IP). Another scenario is when an EL- based LSP is stitched with another LSP which can be EL-based or non- EL based. This document extends the MPLS LSP Ping and Traceroute multipath mechanisms in RFC 6424 to allow the ability of exercising LSPs which make use of the EL. This document updates RFC 4379, RFC 6424, and RFC 6790.
