Draft of message to be sent after approval:
From: The IESG <email@example.com> To: RFC Editor <firstname.lastname@example.org>, email@example.com Cc: The IESG <firstname.lastname@example.org>, <email@example.com>, <firstname.lastname@example.org> Subject: Re: Informational RFC to be: <draft-tsou-diameter-explicit-routing-05.txt> The IESG has no problem with the publication of 'Session-Specific Explicit Diameter Request Routing' <draft-tsou-diameter-explicit-routing-05.txt> as an Informational RFC. The IESG would also like the RFC-Editor to review the comments in the datatracker (http://datatracker.ietf.org/doc/draft-tsou-diameter-explicit-routing/) 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. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-tsou-diameter-explicit-routing/ The process for such documents is described at http://www.rfc-editor.org/indsubs.html Thank you, The IESG Secretary
Technical Summary This document describes a mechanism to enable specific Diameter proxies to remain in the path of all message exchanges constituting a Diameter session. Working Group Summary The document is an individual submission on the RFC Editor Stream. Document Quality Personnel Dan Romascanu is the Responsible Area Director IESG Note The IESG has concluded that this work is related to IETF work done in the Diameter Maintenance and Extensions (DIME) WG. The DIME WG discussed a predecessor of this document. There was no consensus in the WG that the problems addressed by the document are a real concern in existing Diameter deployments, and there was no consensus that the solutions meet the architectural principles of the Diameter protocol. As a result the DIME WG decided not to undertake this work. This relationship does not prevent publishing, but the IESG strongly encourages three changes if the RFC Editor chooses to proceed with the publication of this document. First, the IESG has checked with several other SDOs, and none of them indicate that this document is needed as a reference for them to progress their own work. As such, if the RFC Editor chooses to proceed with the publication of this document, the IESG strongly encourages the removal of the following text from the Abstract: This document is being published to provide the basis for a standardized solution to a problem raised by some architectures (e.g., WLAN 3GPP IP access, 3GPP TS23.234) that use Diameter. The intended use will be as a reference within the non-IETF specification of a Diameter application that meets the needs of these architectures. Second, the document should not claim to represent any aspect of IETF consensus. Therefore, if the RFC Editor chooses to proceed with the publication of this document, the IESG strongly encourages the removal of the following text from the second paragraph of the Introduction: The IETF does not endorse this specification because of its impact on Diameter session survivability, but do not object to its publication for use in specialized situations where the loss of robustness is acceptable. Third, a discussion of the DIME WG discussion should be added to the body of the document or as an IESG note. If an IESG Note is used, please include following text: Techniques similar to those discussed in this document were discussed in the IETF DIME Working Group. The group had no consensus that the problems addressed by such work are a real concern in Diameter deployments. Furthermore, there was no consensus that the proposed solutions are in line with the architectural principles of the Diameter protocol. As a result the working group decided not to undertake the work. There has also not been a formal request for this functionality from any standards body. This RFC represents a continuation of the abandoned work. Readers of this specification should be aware that the IETF has not reviewed this specification and cannot say anything about suitability for a particular purpose or compatibility with the Diameter architecture and other extensions.
