Proposed Normative Text Changes Concerning QoS IBSS

This proposed normative text change aims to prevent malicious use of EDCF in IBSS networks by restricting parameters, ensuring reasonable behavior, and safeguarding against network disruptions caused by unreasonable settings. The changes emphasize the need for user protection, station design improvements, and reliance on QAP settings. By promoting reliable medium use and discouraging non-compliant practices, these adjustments will enhance network security and support 802.11 success. The proposed motion suggests adopting the outlined changes into the current TGe Draft for broader implementation.

  1. Proposed Normative Text ChangesConcerning QoS IBSS Author: Matthew Sherman AT&T Labs - Research mjsherman@att.com Date: May 12, 2003 Matthew Sherman, AT&T Labs

  2. Purpose • Prevent malicious use of EDCF in IBSS Matthew Sherman, AT&T Labs

  3. Background • Existing DCF solutions restrict user parameters selections so that reasonable behavior results in most situations • Existing EDCF solutions allow that EDCF parameters may be set to any value for a station – even if not reasonable • Need to protect the user from himself (and each other Matthew Sherman, AT&T Labs

  4. Background (2) • One malicious user could bring down entire network by choosing unreasonable setting • Should encourage station designs to not permit users to adjust EDCF parameters • Force to receive setting from QAP • Further safeguards may be desired in AP • Infers that should not be able to use EDCF in IBSS or BSS since need QAP Matthew Sherman, AT&T Labs

  5. Market Impact • Reliable use of medium is key to 802.11 success • While non-802.11 complaint use of license free bands is allowed, should not be encouraged • Eg. Use of EDCF in BSS • Vendors need to police themselves to ensure malicious use of their designs is not allowed • Otherwise if malicious use of medium becomes common will limit growth of 802.11 for many applications Matthew Sherman, AT&T Labs

  6. Motion • To adopt the changes identified in document #03/WWWr0 into the current TGe Draft Matthew Sherman, AT&T Labs
