         Multicast Considerations over IEEE 802 Wireless Media
              draft-ietf-mboned-ieee802-mcast-problems-01

Abstract

   Well-known issues with multicast have prevented the deployment of
   multicast in 802.11 [dot11], [mc-props], [mc-prob-stmt], and other
   local-area wireless environments.  IETF multicast experts have been
   meeting together to discuss these issues and provide IEEE updates.
   The mboned working group is chartered to receive regular reports on
   the current state of the deployment of multicast technology, create
   "practice and experience" documents that capture the experience of
   those who have deployed and are deploying various multicast
   technologies, and provide feedback to other relevant working groups.
   This document offers guidance on known limitations and problems with
   wireless multicast.  Also described are various multicast enhancement
   features that have been specified at IETF and IEEE 802 for wireless
   media, as well as some operational chioces that can be taken to
   improve the performace of the network.  Finally, some recommendations
   are provided about the usage and combination of these features and
   operational choices.
