http://grouper.ieee.org/groups/802/2/
Working Group (WG) 802.2 develops standards for Logical Link Control (LLC).
WG 802.2 is inactive (in "hibernation") with no new projects in development. Its completed work is a published standard, variously designated On December 10, 2003, the IEEE-SA Standards Board approved the reaffirmation of Standard 802.2. Participants in the reaffirmation ballot offered 39 comments, which the Working Group studied and discussed. Comments and committee rejoinders are preserved in a Comment Report, which may serve as a useful reference for understanding Std. 802.2. The Chair of WG 802.2 is David Carlson. The sponsor is the LAN and MAN Standards Committee (LMSC), a.k.a. Project 802. ANSI/IEEE Standard 802.2, 1998 Edition is available online at the Get IEEE 802™ home page [ 802.3 CSMA/CD (ETHERNET) ] http://grouper.ieee.org/groups/802/3/ [ 802.4 TOKEN BUS ] http://grouper.ieee.org/groups/802/4/ [ 802.5 Web Site ] http://grouper.ieee.org/groups/802/5/ This is a set of standalone documents that support the committee's work. It includes: This document contains IEEE Stds. 802.5r-1997 and 802.5j-1997 (both approved on September 16th, 1997. DTR is a mode of operation of token ring equipment on dedicated (i.e., point-to-point) links. It defines DTR Concentrators and DTR Stations. DTR Concentrators have C-Ports which have two modes of operation: Port mode, and Station emulation mode. Both DTR Concentrators and DTR Stations may support two access methods: token-passing (TKP) and transmit-immediate (TXI). The full power of DTR is seen on links operating with the TXI access protocol, because this protocol allows the link to carry data at full speed in both directions at once (full-duplex operation). Project scope: Generate a standard for 100 Mbit/s 802.5 Token Ring LANs with MACs based on the present 802.5 Token Ring MAC. It will support 2-pair Category 5 (100 ohm) and STP (150 ohm) cabling based on the 802.3 100BASE-TX PHY and support transmission over optical fibre based on using the 100BASE-X PHY and the FDDI fibre PMD. The standard will consist of specifications for both stations and ports. The Media Access Control (MAX) will operate a dedicated Token Ring link, using the Transmit Immediate (TXI) Access Protocol as defined for 4/16 Mbit/s Token Ring operation with minimal modifications to support operation with the IEEE 802.3 100 Mbit/s Phyisical Layer (100BASE-X PHY). The Token Ring management objects defined for 4/16 Mbit/s operation will continue to be used for 100 Mbit/s operation. The frame format between MAC and LLC will be preserved. Project scope: Define IEEE 802.5 Token Ring (MAC) parameters and minimal augmentation of its operation, physical layer characteristics, and management parameters for transfer of 802.5 format frames at 1,000 Mb/s or faster. The standard will consist of specifications for both stations and ports. MAC frame format will be based on that defined for IEEE 802.5. The frame format between MAC and LLC is being preserved Project scope: Correct errors in 802.5 and its amendments. Scope: Specify extensions to 802.1Q to enhance support for the source route bridging method. Scope: Unification of the token ring standards and supplements with clarification and corrections. Scope: Specify a DTE to DTE logical link which consists of n parallel instances of an 802.5 point-to-point link segment. The logical link will support existing 802.5 MAC clients. Scope: The source route bridging method [802.1d] will be enhanced to provide additional resilience and may be enhanced to provide additional load sharing capabilities.

[ 802.16 Working Group on Broadband Wireless Access Standards ] http://grouper.ieee.org/groups/802/16/ 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. IEEE 802.16 is a unit of the IEEE 802 LAN/MAN Standards Committee, the premier transnational forum for wireless networking standardization. People often take the view that standardization is the enemy of creativity. But I think that standards help make creativity possible -- by allowing for the establishment of an infrastructure, which then leads to enormous entrepreneurialism, creativity, and competitiveness. [ 802.17 Resilient Packet Ring Working Group ] http://grouper.ieee.org/groups/802/17/ The IEEE 802.17 Resilient Packet Ring Working Group (RPRWG) develops standards to support the development and deployment of Resilient Packet Ring networks in Local, Metropolitan, and Wide Area Networks for resilient and efficient transfer of data packets at rates scalable to many gigabits per second. These standards build upon existing Physical Layer specifications, and will develop new PHYs where appropriate. IEEE 802.17 is a unit of the IEEE 802 LAN/MAN Standards Committee. In Metropolitan and Wide Area Networks, fiber optic rings are widely deployed. These rings are currently using protocols that are neither optimized nor scalable to the demands of packet networks, including speed of deployment, bandwidth allocation and throughput, resiliency to faults, and reduced equipment and operational costs.

d) Coexistence of 802 wireless standards specifying devices for unlicensed operation. The working group proposing a wireless project is required to demonstrate Coexistence through the preparation of a Coexistence Assurance (CA) document unless it is not applicable.
If indicated in the five criteria, the wireless working group shall produce a coexistence assurance (CA) document in the process of preparing for working group letter ballot and sponsor ballot. The CA document shall accompany the draft on all wireless working group letter ballots. The CA document shall address coexistence with all relevant approved 802 wireless standards specifying devices for unlicensed operation. The working group should consider other specifications in their identified target band(s) in the CA document. The 802.19 TAG shall have one vote in working group letter ballots that include CA documents. As part of their ballot comments, the 802.19 TAG will verify the CA methodology was applied appropriately and reported correctly. The ballot group makes the determination on whether the coexistence necessary for the standard or amendment has been met if the ballot passes. A representative of the 802.19 TAG should vote in all wireless sponsor ballots that are in the scope of the 802.19 coexistence TAG."

Introduction
(document numbers 22-05-0007-46-0000 and 22-05-0055-07-00 respectively)
The Channel Model document is in the process of being editorially incorporated into the Requirements document as Appendix C and revision 47 of the Requirements document will be posted as soon as that editorial task has been completed (merging two Word docs with different formatting and styles without making a mess of things is a tedious task).
Until the merged document is posted in the September 2005 directory, the separate documents should meet the needs of those who are preparing proposals.
