stds-802-16: SYSREQ: Call for more contributions

[Notice: It is the policy of 802.16 to treat messages posted here as non-confidential.]


The 802.16 System Requirements Task Group is working on a document that
describes system requirements for broadband wireless access systems.  It seeks
input and review by the industry to ensure that the 802.16 standards meets
industry expectations.  The task group hopes to generate a draft by July 5th
for debate and discussion at 802.16's Meeting #1 (July 6-8 in Montreal).

At meeting #0 (May 10-12 in Boulder), we identified some key issues to resolve
and asked for more contributions.  Some people volunteered to provide
contributions and we encourage them to do so, but we are not limited to
contributions just from those volunteers.  Here are 8 specific issues we
identified that need contributions:

1. Provide examples of existing systems: protocols, reference architecture,
terminology, etc. that affect system requirements.  We encourage equipment
vendors to submit their own system requirements so as a group we can ensure
standards we develop are useful and address real market requirements.

2. Support cases, pro or con for any of the bearer services that we listed as
a group (We define "bearer service" to mean a protocol that resides directly
above the MAC layer).  We expect the most important bearer services to
influence requirements of the MAC protocol standard.  The services we listed
at the Boulder meeting are:
   Frame Relay
   Synchronous Transfer Mode (STM): Plesiosynchronous Digital Hierarchy
            (PDH) and Synchronous Digital Hierarchy (SDH).  Examples: T1, E1,
            T3, etc.
   ATM cell relay service
   IP variable length frames (including VoIP and other IP/QoS services)
   802.1 Bridging

3. Provide a description of a QoS-based categorization of applications using
common terminology from IETF and/or ATM worlds.

4. Produce revised reference diagrams, both topological and protocol stack

5. Make a short statement or summary regarding cell size (capacity) in terms
of users and delivered bandwidth to the bearer service.  Other MAC performance
requirements are welcome.

6. Provide a short description of physical layer performance metrics to use as

7. Describe Security: authentication, authorization and privacy protocols; use
of 802.10 or other.

8. Make the case for whether MAC protocol should be optimized for variable
length vs. fixed length frames, or accommodate both well.

Please submit contributions on these topics using the 802.16 Document
Submission Template
Submissions will be considered non-confidential and will be posted for public
access on the System Requirements Area of the 802.16 Web Site, unless you have
a strong requirement for password protection.  If you have a substantial
contribution and require some password protection or control over distribution
due to copyright or other confidentiality requirements, please contact Roger
Marks (r.b.marks@ieee.gov) to make arrangements.  However, the 802.16 group
encourages open, unprotected communications.

For consideration for incorporating your contribution in the System
Requirements document and at the July 6-8 meeting, submit your contributions
no later than June 14, 1999 to the Editor of the 802.16 System
Requirements Document (Brian Petry).
