stds-802-16: 2 PARs submitted by 802.11
At the March 802 Plenary, 802.11 will be asking approval for the two
PARs described below. If we have concerns or objections, we may
submit them in written form by 5 pm on Tuesday, 7 March, 5:00 pm.
Please bring any issues to my attention.
(1) Medium Access Method (MAC) Enhancements
Enhance the 802.11 Medium Access Control (MAC) to improve and manage
Quality of Service, provide classes of service, and enhanced security
and authentication mechanisms. Consider efficiency enhancements in
the areas of the Distributed Coordination Function (DCF) and Point
Coordination Function (PCF)
To enhance the current 802.11 MAC to expand support for applications
with Quality of Service requirements. Provide improvements in
security, and in the capabilities and efficiency of the protocol.
These enhancements, in combination with recent improvements in PHY
capabilities from 802.11a and 802.11b, will increase overall system
performance, and expand the application space for 802.11.
(2) Recommended Practices for Multi-Vendor Access Point
Interoperability via Inter-Access Point Protocol across Distribution
Systems supporting IEEE P802.11 operation
To develop recommended practices for an Inter-Access Point Protocol
(IAPP) which provides the necessary capabilities to achieve
multi-vendor Access Point interoperability across a Distribution
System supporting IEEE P802.11 Wireless LAN Links. This IAPP will be
developed for the following environment(s): 1) A Distribution System
consisting of IEEE 802 LAN components supporting an IETF IP
environment; 2) Others as deemed appropriate.
IEEE P802.11 specifies the MAC and PHY layers of a Wireless LAN
system and includes the basic architecture of such systems, including
the concepts of Access Points and Distribution Systems.
Implementation of these concepts where purposely not defined by
P802.11 because there are many ways to create a Wireless LAN system.
Additionally many of the possible implementation approaches involve
concepts from higher network layers. While this leaves great
flexibility in Distributions System and Access Point functional
design, the associated cost is that physical Access Point devices
from different vendors are unlikely to inter-operate across a
Distribution System due to the different approaches taken to
Distribution System design. As P802.11 based systems have grown in
popularity, this limitation has become an impediment to WLAN market
growth. At the same time it has become clear that there are a small
number of Distribution System environments that comprise the bulk of
the commercial WLAN system installations. This project proposes to
specify the necessary information that needs to be exchanged between
Access Points to support the P802.11 DS functions. The information
exchanges required will be specified for, one or more Distribution
Systems; in a manner sufficient to enable the implementation of
Distribution Systems containing Access Points from different vendors
which adhere to the recommended practices.
