Postscript: Status of IP transport work in Wimax Forum 2 approaches being developed in parallel in Network Working Group: Broadcast network emulation based on 802.3/Ethernet Convergence Sublayer types (for IPv4 and IPv6) supports optional PPPoE mode of operation Approach based on IPv4 Convergence Sublayer type (ie. Raw IP datagrams as the 802.16 payload) Minimal details in NWG spec currently, eg. no description of how to perform IP address resolution Wimax Forum Network Working Group is committed to supporting both these approaches in its end-to-end architecture Wimax Forum Profiles group (MTG) is currently considering whether to endorse one particular approach or mandate support of both (despite the fact that both these approaches remain largely unpublished “work-in-progress”). The problem of IPv4/IPv6 support in 802.16 can benefit from IETF expertise and standardization |
