DETAILS - IEEE 802 Standards News Bulletin

The IEEE 802® LAN/MAN Standards Committee encompasses many evolving wired and wireless local and metropolitan area network technologies. Decisions made by the eight active IEEE 802 Standards Working Groups will shape communications for years to come. The Committee functions within the Institute of Electrical and Electronics Engineers Standards Association (IEEE-SA), a leading international membership organization serving today's industries with a complete portfolio of standards programs.

Given the great interest in these groups and their actions, IEEE-SA has created this e-mail News Bulletin for the news media and other interested parties. This issue covers Working Group activities during the IEEE 802 Plenary Meeting, 9-14 March 2003 in Dallas, Texas, USA. Nearly 850 people from approximately 400 organizations attended. To go directly to the activities for a specific Working Group, click on a button below.

Note: This Bulletin details the status of active IEEE 802 standards efforts. Each one follows a well-defined process from concept to completion. For an overview of how consensus standards are developed at the IEEE, see http://standards.ieee.org/resources/development/. The glossary at the end of this bulletin can be of help in understanding many of the terms used below.

The IEEE 802® LAN/MAN Standards Committee The IEEE 802® LAN/MAN Standards Committee (LMSC) develops local and metropolitan area network standards. The most widely used standards are for Ethernet, token ring, wireless LANs, bridging, and virtual bridged LANs. Its ongoing technical work is helpful in ushering new technologies into the market. Individual Working Groups provide the focus in each area.

Extension to IEEE 802b to Document Object Identifier Registration
A new PAR, P802b, has been approved to extend IEEE Std 802, "Overview and Architecture," so it can document IEEE 802 procedures that allocate the object identifier values used in IEEE 802 standards. An initial draft of the new material has been circulated, and is expected to be issued for its first Working Group ballot in March.

Handoff Study Group Created
The Sponsor Executive Committee created the IEEE 802 Executive Committee Study Group on Handoff to consider the possibility of developing a standard specifying a common handoff framework for 802 wired and wireless standards. This decision followed a Call for Interest at the March meeting and a tutorial last November. If the work proceeds, it could allow devices having interfaces to multiple IEEE 802 networks to move from one to another without losing high-layer connectivity. David Johnston (dj.johnston@intel.com) was named as Chair.

Upcoming IEEE 802 Meetings:
* 21-24 July 2003 -- IEEE Plenary Meeting in San Francisco, CA, USA

The IEEE 802.1™ Working Group This Working Group develops standards and recommended practices in IEEE 802 LAN/MAN architecture; enables internetworking among IEEE 802 LANs, MANs and other wide area networks; provides for IEEE 802 overall network management; and creates advanced protocol layers.<http://www.ieee802.org/1/>

IEEE Std 802.1s Published
IEEE 802.1s, the Multiple Spanning Trees extension of the virtual LAN standard, was published in January 2003.

New Edition of IEEE Std 802.1Q
A 2003 Edition of the IEEE 802.1Q virtual LAN standard is currently under development. The 2003 Edition will incorporate all existing amendments to the 802.1Q standard (802.1u, 802.1v, and 802.1s) into the base text.

Maintenance of IEEE Std 802.1X
IEEE P802.1aa, the maintenance draft for IEEE 802.1X, has been revised following its first Working Group Ballot and will be issued for a further Working Group ballot. It is expected that the draft will be issued for Sponsor Ballot in the July/August timeframe.

Extension to IEEE 803 VLAN Bridging Technology Planned to Support Service Provision
Approval was given to the Project Authorization Request (PAR) to extend IEEE 802 Virtual LAN Bridging technology to support the service provision. The extension would make it easier to use this technology in conjunction with work underway in the Internet Engineering Task Force (IETF) on Layer 2 Virtual Private Networks. Work under the PAR, IEEE P802.1ad, "Provider Bridges," will seek to define the technology needed to support IEEE 802 VLAN technology in service provision environments.

Revision of IEEE 802.1D on Media Access Control (MAC) Bridges
The maintenance PAR for the IEEE 802.1D standard, IEEE P802.1y, has been withdrawn and replaced by a revision PAR, IEEE P802.1D. Existing maintenance items in IEEE P802.1y have been incorporated into the revision project. The revision also removes support for the original Spanning Tree protocol (STP), because the newer Rapid Spanning Tree protocol (RSTP) has rendered STP obsolete. The revision underwent its first Working Group Ballot and should be submitted for a confirmation ballot in the April/May timeframe. It may be submitted for Sponsor Ballot in July.

Discovery Protocol to Task Group Ballot
Work on link layer discovery mechanisms under IEEE P802.1AB progressed to its initial Task Group Ballot, which closed during February. Following resolution of ballot comments, it is expected that the draft will be issued for a confirmation ballot in April/May.

Link Security Study Group Placed in 802.1
It was agreed that the Link Security Executive Committee Study Group (see detail in the final section of this Bulletin) will become a Study Group of the IEEE 802.1 Working Group. This move will allow closer cooperation between security experts in IEEE 802.

For details, contact Tony Jeffree, IEEE 802.1 Working Group Chair, at tony@jeffree.co.uk.

Upcoming IEEE 802.1 Meetings:
* 2-6 June 2003, Interim Meeting in Ottawa, Canada
* 21-24 July 2003 -- IEEE Plenary Meeting in San Francisco, CA, USA

IEEE P802.3af Goes to Sponsor Ballot
The IEEE P802.3af "DTE Power via the MDI" Task Force is nearing completion of its work. The IEEE 802 Sponsor Executive Committee approved submission of IEEE P802.3af to RevCom conditional on successful completion of the Sponsor Ballot process. The IEEE P802.3af Task Force addressed comments generated during a Sponsor Ballot recirculation of IEEE P802.3af/D4.1 and made changes to the draft to produce IEEE 802.3af/D4.2, which will be the subject of a second Sponsor Ballot recirculation. When approved by the IEEE Standards Board, IEEE 802.3af will standardize the delivery of DC power over the unshielded twisted-pair copper cabling used for the most popular versions of Ethernet. It will reduce the complexity and cost of deploying devices, such as Ethernet hubs and IEEE 802.11 access points, by eliminating separate power supplies and the corresponding need for nearby AC power outlets.

IEEE P802.3ah Continues Development of Draft
The IEEE P802.3ah "Ethernet in the First Mile" Task Force continued work on its draft. IEEE P802.3ah/D1.3 was the subject of Task Force review prior to the meeting. Draft 1.4 will be released following the meeting with all changes from the review. The Ethernet in the First Mile project will define Ethernet operation in access markets. New fiber optic transmission options optimized for access networks will ease the deployment of 100 Mb/s and 1000 Mb/s Ethernet for fiber-to-the-home and fiber-to-the-cabinet. Other specifications define operation over the installed copper cable runs to businesses and homes. These technologies can be combined for hybrid fiber/copper access networks. A third class of EFM access technology, Ethernet Passive Optical Networks, provide a second option for deployment of access Ethernet using fiber optics.

IEEE P802.3aj Sponsor Ballot Approved
This is the seventh maintenance project since the original publication of IEEE Std 802.3 in 1985. The IEEE 802.3 Maintenance Task Force addressed comments made in response to the IEEE P802.3aj/D1.1 working group recirculation ballot. This project includes changes from 10 separate revision requests covering IEEE Std 802.3-2002 and IEEE Std 802.3ae-2002.

IEEE 802.3 10GBASE-CX4 Working Group Ballot Approved
The IEEE 802.3 Study Group has set an aggressive schedule to add a copper media option to 10 Gigabit Ethernet. IEEE 802.3ae-2002 only specifies fiber optic media for data transmission. The XAUI interface included in the IEEE Std 802.3ae is designed for chip-to-chip interconnect, but is easily extended over balanced shielded copper cabling for box-to-box interconnection. The 10GBASE-CX4 Study Group submitted a PAR, supporting information and a working paper for preview before the meeting. IEEE 802 forwarded the PAR to the IEEE Standards Board for consideration at its March meeting. IEEE 802.3 authorized a Working Group Ballot contingent on approval of the PAR. If the PAR is approved, IEEE P802.3ak/D1.0 will be issued in late March.

IEEE 802.3 10GBASE-T Study Group Underway
All speeds of Ethernet operation, except 10 Gb/s, include interfaces for unshielded twisted pair cabling. Ethernet's auto-negotiation capability allows implementations to support multiple speeds for easier migration to higher speeds by allowing the switch and NIC ends of a link to be upgraded independently. The ease of migration, coupled with the low costs of UTP interfaces have been important factors in Ethernet's dominance in enterprise and home networks. The Study Group is studying the technical options and requirements for operation over horizontal cabling specified in TIA 568 and ISO/IEC 11801 building cabling standards. (Horizontal cable runs from an equipment closet to workspaces.) The IEEE 10GBASE-T Study Group plans to submit a PAR for consideration at the July IEEE 802 plenary meeting.

Upcoming IEEE 802.3 Meetings:
* 21-24 July 2003 -- IEEE Plenary Meeting in San Francisco, CA, USA

Consolidation of IEEE 802.11 to Be Recirculated
The 2003 edition of IEEE 802.11 was submitted to the IEEE's REVCOM at their March 18 meeting and it was determined that the final document must go through a Sponsor Recirculation Ballot. This edition rolls together the added PHY options, e.g. 802.11a and 802.11b, plus various other amendments created since 1999. The 2003 edition will be a new baseline to which the upcoming amendments (e, f, g, h, i, j, k, etc.) can be added. After IEEE approval, it will be requested that ISO/IEC consider the new edition for fast track approval.

QoS Amendment Sent to Working Group Recirculation Ballot
Task Group e resolved all comments from the last Working Group Letter Ballot and is in the final stages of preparing for a Working Group Recirculation Ballot, which should occur shortly after the May interim meeting. The IEEE P802.11e amendment will provide for standardized Quality of Service (QoS) to enhance voice, video and other time-bounded or prioritized network traffic.

IEEE P802.11f to Undergo Third Sponsor Ballot
The Inter Access Point Protocol Working Group addressed the responses to its second Sponsor Recirculation Ballot and prepared a revised draft for submission for another Sponsor Recirculation Ballot.

IEEE P802.11g Completes Draft 7.0
The IEEE P802.11g Task Group updated the draft standard to create version 7.0, which will be submitted for Sponsor Recirculation Ballot. The group is still targeting final approval in June 2003.

European 5 GHz Draft Revised
IEEE P802.11h for spectrum managed IEEE 802.11a devices is in its final stages. Responses to the Sponsor Ballot were processed and a revised draft is being prepared for a Sponsor Recirculation Ballot. This amendment will add the dynamic frequency selection and transmit power control functions for operation of 5GHz products in parts of Europe.

IEEE 802.11i Security Specification Continues Comment Resolution
The security experts working within the IEEE P802.11i group addressed comments from Working Group Letter Ballot 52. Comment resolution is expected to continue through the May interim meeting.

First Specification Completed for the Japan 4.9 GHz Amendment
The IEEE P802.11j amendment will specify how products must operate for use in the newly allocated 4.9 - 5 GHz frequency bands in Japan. The Working Group finalized a complete draft specification and approved issuing it for a Working Group Letter Ballot.

Radio Resources Management Group Refines Vision and Architecture
The IEEE P802.11k Working Group continued to refine the Vision and Architecture document for standardized radio resource measurements. This standard will enable WLAN systems to use resources more efficiently.

IEEE 802.11m Maintenance Group Seeking Input
This group, recently formed to address maintenance issues for IEEE 802.11 standards, has developed a work plan under which it will solicit input from the entire IEEE 802.11 Working Group to clarify areas within IEEE 802.11 that are ambiguous and subject to interpretation.

High Throughput Study to Become a Task Group
The High Throughput Study Group completed its PAR for submission to the IEEE 802 Executive Committee for the creation of a High Throughput Task Group. A chair for the new group was selected and the new Task Group, IEEE 802.11n, which will begin work immediately even though it will not get official recognition until September.

For additional details on these items, contact Stuart Kerry, IEEE 802.11 Chair, at stuart.kerry@philips.com

Upcoming IEEE 802.11 Meetings:
* 12-15 May 2003 -- IEEE 802.11 interim meeting in Dallas, TX in conjunction with meetings of the other 802 wireless groups
* 21-24 July 2003 -- IEEE Plenary Meeting in San Francisco, CA, USA

Task Group 2 (Coexistence) Targets the June RevCom Agenda
An Initial Sponsor Ballot for TG2 was returned with an approval rating above 90%. The Task Group spent the March session working on comment resolution and, pending an SEC electronic ballot approval, will move to a Recirculation in April. Then, pending an Executive Committee electronic ballot approval (to close before a May 5 deadline), TG2 will be put on the June RevCom agenda. This will trigger the release of the recommended practices document "Part 15.2: Coexistence of Wireless Personal Area Networks with Other Wireless Devices Operating in Unlicensed Frequency Bands."

Task Group 3 (High Data Rate) Targets Final Recirculation of Sponsor Ballot in April
The last TG3 Sponsor Ballot received an approval rating of over 97%. The Task Group reviewed all technical comments made and is preparing an updated Draft (D17) for Recirculation Ballot in April. The IEEE-SA will have prestandard copies of "Part 15.3: Wireless Medium Access Control (MAC) and Physical Layer (PHY) Specifications for High Rate Wireless Personal Area Networks (WPAN)" available for distribution in April. The IEEE 802.15.3 Draft Standard is expected to be submitted for final approval by RevCom in June.

Task Group 4 (Low Data Rate) Seeks REVCOM Approval for Spec Release
The last Sponsor Ballot recirculation received 100% approval. The Group has now completed the editorial comment recommendation document and will submit this along with the draft specification to RevCom for approval in April. This would trigger release of the document "Standard for Part 15.4: Wireless Medium Access Control (MAC) and Physical Layer (PHY) specifications for Low Rate Wireless Personal Area Networks (LR-WPANs)". A Low Rate UWB team will remain active as an Interest Group.

23 Proposals Presented to Task Group 3a for Alternate Higher Rate PHY Baseline Standard
Twenty-three 40-minute presentations were made during the March meeting. These responded to the Request-for-Proposal for a new 'higher-rate PHY' as an alternative to the 55 Mbps, 2.4 GHz PHY existing in the upcoming 802.15.3 Standard. The proposals were mostly UWB-based, but also included several narrowband approaches. Although all 31 RFI respondents remain active and are eligible to present in May, it is anticipated that there will actually less than the 23 seen in March due to a healthy proposal consolidation process (this is not an IEEE process). A down-selection procedure is in place that will start following two more rounds of presentations in May and July.

IEEE 802.16 Holds January Session #23 Alongside Wireless Communications Association
The 802.16 Working Group held its January 2003 Session #23 in San Jose, CA, USA in conjunction with the annual Technical Symposium of the Wireless Communications Association.

IEEE 802.16a, Extending WirelessMAN Air Interface to 2-11 GHz, Receives Final Approval
IEEE 802.16a was approved by the IEEE-SA Standards Board on 29 January 2003. The standard, a non-line-of-sight extension of the global IEEE 802.16 WirelessMAN standard for 10-66 GHz published in April 2002, provides for fixed broadband wireless access (BWA) in both licensed and license-exempt 2-11 GHz bands. Publication of the standard is expected in late March 2003.

Mobile WirelessMAN (802.16e) Project Meets for Second Time
Task Group e met for the second time to develop IEEE 802.16e, which will enhance the WirelessMAN air interface for fixed/mobile support. The group reviewed 13 contributed documents and spent considerable effort addressing the output of the IEEE 802.16e Handoff ad hoc committee. The group adopted a working document and will solicit comments through a Task Group Review. The schedule calls for completing a ballotable IEEE 802.16e draft by July 2003.

IEEE 802.16a-Based System Profiles Advance in 802.16d
Task Group d met for the second time on the IEEE 802.16d project, which will create system profiles to support compliance testing related to IEEE 802.16a. Sixteen contributed documents were reviewed. The Working Group decided to incorporate the output from Task Group d as Draft 1 of the IEEE 802.16d amendment and initiate a Working Group Letter Ballot on it.

Final Draft of Recommended Practice IEEE P802.16.2a Nears IEEE-SA Submittal
Draft 5 of the IEEE 802.16.2a Recommended Practice on coexistence, including recommendations for 2-11 GHz, has nearly completed its IEEE Sponsor Ballot. Recirculation of comments, without changes to the previously recirculated draft, will begin shortly. The 802 SEC approved the Working Group's request to forward the draft for approval as an IEEE Standard, provided that it successfully completes a final recirculation.

Interoperability Documentation for 10-66 GHz Proceeds Rapidly
Task Group C continued its progress toward interoperability documentation for the 10-66 GHz WirelessMAN-SC air interface. Work progressed on three projects:

The initial Sponsor Ballot for the IEEE 1802.16.1 Protocol Implementation Conformance Statement (PICS) draft concluded successfully. The Working Group resolved comments and will initiate a Recirculation Ballot. In the meantime, the 802 SEC granted conditional approval to forward the draft for IEEE-Standard Association approval if the resolutions are accepted by the ballot group.The Working Group adopted a draft of the IEEE 1802.16.2 Test Suite Structure and Test Purposes document and agreed to open a Working Group Letter Ballot for it.

The 802 SEC agreed to forward a PAR for IEEE 1802.16.3, requesting that the IEEE-SA Standards Board open a new project on Radio Conformance Tests.

IEEE 802 Link Security Executive Committee Study Group (ECSG) This Study Group was formed in November 2002 to evaluate link security architecture issues, develop a PAR and 5 criteria for a new standard for link security that can be applied to IEEE 802 networks (especially for IEEE 802.3 networks) and recommend where the project should be placed within IEEE 802.

First Interim Meeting Activities
At the ECSG's first Interim meeting in January 2003, it began evaluating existing IEEE 802 security architectures and discussed the development of a PAR and 5 criteria. It also discussed the placement of the project within IEEE 802 and approved to become part of the IEEE 802.1 Working Group.

March Plenary Meeting Activities
At the March Plenary Meeting, three tutorials provided background on the three major areas related to this project: Bridging, Ethernet Passive Optical Networks (EPONs) and Security. In addition, it approved an initial set of scenarios and objectives, began working on threat analysis related to these scenarios, and considered in detail several security architecture models. It was reapproved by the Executive Committee and placed in the IEEE 802.1 Working Group, as recommended by the Study Group. The charter of the group remains unchanged, i.e., the evaluation and recommendation of security architectures for IEEE 802 and develop a PAR and 5 criteria for the specification of a security standard for IEEE 802 bridged networks and IEEE 802.3 links.
