Networks(16ng)
The Secretariat inadvertently failed to send the "WG Review: IP over
IEEE
802.16 Networks (16ng)" message to the new-work mailing list on May 2nd.
Please accept our apology. However, the draft charter was not approved
by the IESG at the May 11th IESG teleconference, and an updated version
will be reviewed by the IESG on May 25th. The following revised draft
charter was submitted, and is provided for informational purposes only.
Please send your comments to the IESG mailing list (iesg@ietf.org) by
May 24th.

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 the IEEE 802.16 network
architecture.
Also, other standards bodies are carrying out similar efforts (e.g.,
WiBro-Wireless Broadband in Korea).
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]
16ng will not initially consider other work items than the ones listed
above; however, other works related to improved IP over 16ng may occur
in other relevant WGs, and 16ng will participate and help coordinate
with such efforts.
This working group will take dual stack operation into account in its
specifications, and reuse existing specifications whenever reasonable
and possible.

Requirement to the IESG for considerations of publication
