The IESG has approved the following document: - 'Teredo Extensions ' <draft-thaler-v6ops-teredo-extensions-08.txt> as a Proposed Standard This document has been reviewed in the IETF but is not the product of an IETF Working Group. The IESG contact person is Jari Arkko. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-thaler-v6ops-teredo-extensions-08.txt Technical Summary This document specifies a set of extensions to the Teredo protocol. These extensions provide additional capabilities to Teredo, including support for more types of NATs, and support for more efficient communication (fewer signaling packets). A companion document, draft-krishnan-v6ops-teredo-update specifies a set of security updates for Teredo that mitigate a number of security concerns. Microsoft's own spec [MS-TERE] combined teredo-update and teredo-extensions applies to both. It's also worth noting that a third document draft-ietf-v6ops-tunnel-security-concerns discusses security issues and potential mitigations regarding tunneling more generally. Working Group Summary Draft-krishnan-v6ops-teredo-update is closely related to draft-thaler-v6ops-teredo-extensions. The "Teredo update" is a set of simple security fixes to the base Teredo protocol to reflect what actually got implemented and deployed. (The history is that Symantec originally wrote the security concerns document and made a number of security recommendations, which mostly match what Vista and Windows 7 actually do, and the recommendations were what then became teredo-update. When the WG reviewed the recommendations, the only ones that had WG consensus turned out to be the same ones that Vista and Windows 7 did, and the other things were either removed or made MAY's to reflect WG consensus.) Remi Denis made very useful comments publically during the WGLCs. In addition, the TC previously did thorough reviews. Document Quality One "full" implementation is known to exist - Windows 7 includes all extensions specified, and Vista includes almost all of them. However, separate partial implementations were done by test suite compliance developers and parser developers. Personnel There is no document shepherd. Jari Arkko is the responsible Area Director. _______________________________________________ IETF-Announce mailing list IETF-Announce@ietf.org https://www.ietf.org/mailman/listinfo/ietf-announce
