The IESG has approved the following document: - 'Transmission of IP over Ethernet over IEEE 802.16 Networks ' <draft-ietf-16ng-ip-over-ethernet-over-802-dot-16-12.txt> as a Proposed Standard This document is the product of the IP over IEEE 802.16 Networks Working Group. The IESG contact persons are Ralph Droms and Jari Arkko. A URL of this Internet-Draft is: http://www.ietf.org/internet-drafts/draft-ietf-16ng-ip-over-ethernet-over-802-dot-16-12.txt Technical Summary This document describes the transmission of IPv4 over Ethernet as well as IPv6 over Ethernet in an access network deploying the IEEE 802.16 cellular radio transmission technology. The Ethernet on top of IEEE 802.16 is realized by bridging connections which the IEEE 802.16 provides between a base station and its associated subscriber stations. Due to the resource constraints of radio transmission systems and the limitations of the IEEE 802.16 MAC functionality for the realization of an Ethernet, the transmission of IP over Ethernet over IEEE 802.16 may considerably benefit by adding IP specific support functions in the Ethernet over IEEE 802.16 while maintaining full compatibility with standard IP over Ethernet behavior. Working Group Summary The document underwent much discussion, sometimes heated on topics such as distributed versus centralized bridges, whether to use the point-to-multipoint 'multicast' capabilities of the 802.16 link-layer, and about the proper choice of MTU. The document captures consensus and includes some of the relevant discussions including pros and cons of decisions taken. The appendix of the document includes much text in this respect. Document Quality There has been a review including IEEE 802.16 and WiMAX folks in addition to the WG. There was a first WG LC ending on September 7, 2007. The resulting revision was subjected to detailed review by the IEEE 802.16 committee. That feedback was discussed at IETF 71 in Philadelphia and the relevant changes incorporated. The document was submitted to a second WG last call subsequent to Philadelphia and those changes have been fed into the current version being submitted to the IESG (version 6). Personnel Gabriel Montenegro <gmonte@microsoft.com> is the Document Shepherd for this document. Ralph Droms <rdroms@cisco.com> is the responsible AD. RFC Editor Note Delete first two sentences from the third paragraph in the Introduction. OLD: Ethernet is a widely deployed transmission technology. It provides unicast transport, handles broadcast and multicast traffic efficiently, and provides rich services such as Virtual LANs. However, Ethernet has been originally architected and designed for a shared medium while the IEEE 802.16 uses a point-to-multipoint architecture like other cellular radio transmission systems. Hence, Ethernet on top of IEEE 802.16 is realized by bridging between IEEE 802.16 radio connections between a BS (Base Station) and its associated SSs (Subscriber Stations).
