Congestion Control for Multicast IP
The performance degradation of the current M-bone and its possible development
to a more stable and widely spread infrastructure pose the problem of congestion
avoidance for multicast wide area networks. Two
ways seem viable to face it: resource reservation and/or application
adaption. The first solution is probably the only acceptable for applications
that have throughput and/or latency constraints. On the other side, applications
that can adapt to the quality of service offered by the network, are potential
good citizens for the traditional best effort portion of the M-bone. For
these applications, end-to-end congestion control mechanisms are being
studied by the research community.
This presentation will concern multicast congestion control through
application adaption. It will review the basic mechanisms proposed so far
concentrating on two of them: `store-and-forward (transcoder) agents'
and `layered receiver driven'. Major problems such as scalability and TCP-friendliness
will be considered in the discussion.
Slides will be displayed in wb.
