IP over IEEE 802.16 Networks (16ng) ----------------------------------- Charter Last Modified: 2009-07-02 Current Status: Active Working Group Chair(s): Gabriel Montenegro Soohong Daniel Park Internet Area Director(s): Ralph Droms Jari Arkko Internet Area Advisor: Ralph Droms Technical Advisor(s): Maximilian Riegel Dave Thaler Secretary(ies): Jihoon Lee Mailing Lists: General Discussion:16ng@ietf.org To Subscribe: https://www.ietf.org/mailman/listinfo/16ng Archive: http://www.ietf.org/mail-archive/web/16ng Description of Working Group: Broadband Wireless Access Networks address the inadequacies of low bandwidth wireless communication for user requirements such as high quality data/voice service, wide coverage, etc. The IEEE 802.16 Working Group on Broadband Wireless Access Standards develops standards and recommended practices to support the development and deployment of Broadband Wireless Metropolitan Area Networks. A particularity of IEEE 802.16 is that it does not include a rigid upper edge MAC service interface. Instead, it provides multiple "convergence sublayers (CS)" with the assumption that the choice and configuration of the upper edge will be done in accordance with the needs of a specific deployment environment (which might be DSL replacement, mobile access, 802.11 or CDMA backhaul etc.). Specifically, immediately subsequent to network entry, an 802.16 subscriber station has no capability whatsoever for data (as opposed to management) connectivity. Especially, in IP CS case, the criteria by which the Base Station (or other headend elements) sets up the 802.16 MAC connections for data transport are not part of the 802.16 standard, and depend on the type of data services being offered (e.g., the set up of link layer connections will be different for IPv4 and IPv6 services). Additionally - as IEEE 802.16 is a point-to-multipoint network ? an 802.16 subscriber station is not capable of multicasting (e.g., for neighbor discovery, ARP, IP multicasting services, etc.) or direct communication to the other nodes attached to the same Base Station within the same subnet (prefix). Unlike 3G or xDSL technologies, IEEE 802.16 is not part of an end-to- end system definition. Currently, the WiMAX Forum, and, in particular, its NWG (Network Working Group) is defining a network architecture based on IEEE 802.16. The principal objective of the 16ng working group is to specify the operation of IPv4 and IPv6 over IEEE 802.16, taking into account the IPv4, IPv6 and Ethernet Convergence Sublayers. The working group may issue recommendations to IEEE 802.16 and WiMax aiming at improving support for IP. The scope of this working group is as follows (WG Deliverables); - Produce "16ng Problem Statement, Goal and Requirement" to identify the specific gaps in the 802.16 MAC for IPv4/IPv6 support, describe possible network models (ie. point-to-point, broadcast etc.), and provide 16ng related terminology to be used for the base guideline while defining solution frameworks. [Informational RFC] - Produce "IPv6 over IEEE 802.16 Networks in conjunction with IPv6 CS" to define IPv6 operation including the transmission of IPv6 over IEEE 802.16 link, Neighbor Discovery Protocol, Stateful (DHCPv6) and Stateless Address Configuration, Broadcast, Multicast, etc. [Proposed Standard RFC] - Produce "IPv6 over IEEE 802.16 Networks in conjunction with Ethernet CS" to define IPv6 operation including the transmission of IPv6 over IEEE 802.16 link, Neighbor Discovery Protocol, Stateful (DHCPv6) and Stateless Address Configuration, Broadcast, Multicast, etc. [Proposed Standard RFC] - Produce "IPv4 over IEEE 802.16 Networks in conjunction with IPv4 CS" to define IPv4 operation including the transmission of IPv4 over IEEE 802.16 links, ARP operation, Stateful Address Configuration (DHCPv4), Broadcast, Multicast, etc [Proposed Standard RFC] - Produce "IPv4 over IEEE 802.16 Networks in conjunction with Ethernet CS" to define IPv4 operation including the transmission of IPv4 over IEEE 802.16 links, ARP operation, Stateful Address Configuration (DHCPv4), Broadcast, Multicast, etc [Proposed Standard RFC] - Produce "IP deployment over IEEE 802.16 Networks" to illustrate the IP deployment scenarios including IP CS and Ethernet CS considerations over IEEE 802.16 networks based on the WiMAX and WiBro. [Informational RFC] This working group will take dual stack operation into account in its specifications, and reuse existing specifications whenever reasonable and possible. The ability to negotiate the used Convergence Sublayer is required, as no single mandatory CS can be specified for the clients. Work based on the Ethernet CS needs to take into account interoperability with existing hosts and other devices that employ Ethernet? to allow bridging.
