Hi, all, We have published a -07 version of lightweight 4over6. This new version improves the preciseness of the ICMP handling mechanism description.
Up to now, this draft has finished merging with I-D.zhou-softwire-b4-nat and I-D.penno-softwire-sdnat as requested by the WG and has settled all the technical details based on comments from the WG. It reflects widely requirements from 7 operators including China Telecom, Tsinghua, Comcast, France Telecom, Deutsche Telekom,Bouygues Telecom and Freebits, and vendors from Huawei, Juniper and Cisco. It has running code already published in http://sourceforge.net/projects/laft6/ and has a field trial in commerial network. >From the authors of this document's view, it is ready to be adopted as working group document. We would be appreciated to have your comments. Thanks in advance ! Best wishes Qiong ---------- Forwarded message ---------- A new version of I-D, draft-cui-softwire-b4-translated-ds-lite-07.txt has been successfully submitted by Ian Farrer and posted to the IETF repository. Filename: draft-cui-softwire-b4-translated-ds-lite Revision: 07 Title: Lightweight 4over6: An Extension to the DS-Lite Architecture Creation date: 2012-07-13 WG ID: Individual Submission Number of pages: 16 URL: http://www.ietf.org/internet-drafts/draft-cui-softwire-b4-translated-ds-lite-07.txt Status: http://datatracker.ietf.org/doc/draft-cui-softwire-b4-translated-ds-lite Htmlized: http://tools.ietf.org/html/draft-cui-softwire-b4-translated-ds-lite-07 Diff: http://tools.ietf.org/rfcdiff?url2=draft-cui-softwire-b4-translated-ds-lite-07 Abstract: This document specifies an extension to DS-Lite called Lightweight 4over6. This mechanism moves the translation function from the tunnel concentrator (AFTR) to initiators (B4s), and hence reduces the mapping scale on the concentrator to a per-subscriber level. To delegate the NAPT function to the initiators, port-restricted IPv4 addresses are allocated to the initiators.
