PPP Over Ethernet (PPPoE) Extensions for Credit Flow and Link Metrics
Draft of message to be sent after approval:
From: The IESG <email@example.com> To: RFC Editor <firstname.lastname@example.org> Cc: The IESG <email@example.com>, <firstname.lastname@example.org>, email@example.com Subject: Re: Informational RFC to be: draft-bberry-pppoe-credit-07.txt The IESG has no problem with the publication of 'PPP Over Ethernet (PPPoE) Extensions for Credit Flow and Link Metrics' <draft-bberry-pppoe-credit-07.txt> as an Informational RFC. The IESG would also like the IRSG or RFC-Editor to review the comments in the datatracker (https://datatracker.ietf.org/public/pidtracker.cgi?command=view_id&dTag=11629&rfc_flag=0) related to this document and determine whether or not they merit incorporation into the document. Comments may exist in both the ballot and the comment log. The IESG contact person is Mark Townsley. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-bberry-pppoe-credit-07.txt The process for such documents is described at http://www.rfc-editor.org/indsubs.html. Thank you, The IESG Secretary
Technical Summary This document extends the Point-to-Point Over Ethernet (PPPoE) Protocol  with a credit-based flow control mechanism and Link Quality Metric report. This optional extension should improve the performance of PPPoE over media with variable bandwidth and limited buffering, such as mobile radio links. Working Group Summary This is an individual submission. However, the pppext WG provided review. See RFC Editor's note for pppext warning about this submission. Protocol Quality This document received extensive review from the pppext WG. The document was also reviewed by Mark Townsley. We are told that there are two independent, interoperable, implementations and that it has been deployed. Note to RFC Editor 2. The IESG thinks that this work is related to IETF work done in WG pppext, but this does not prevent publishing. Editor, this document defines new PPPoE tags and messages. The PPPoE IANA registry for PPPoE is in the process of being set up, as defined in draft-arberg-pppoe-iana-00.txt (which is targeted to become a BCP). Please include a reference to this document for tag/message allocation and go through IANA to obtain the values. Please see Comments in the tracker, which include some constructive recommendations for this document. IESG Note "The PPP Extensions Working Group (pppext) has reservations about the desirability of the feature described in this document. In particular, it solves a general problem at an inappropriate layer and it may have unpredictable interactions with higher and lower level protocols. The techniques described in this document are intended for use with a particular deployment technique that uses a PPP termination separated from a radio termination by an Ethernet, and that has radio-side flow control for a slower PPP-only link to remote nodes. Implementors are better advised to avoid split termination with inter-media protocol translation, and use standard Internet Protocol routing instead."
