Abstract
Real time multicast video distribution is an important
component of many multimedia applications. Our work
addresses the fairness problem in feedback­controlled mul­
ticast video distribution systems over best effort networks
(such as the Internet). In previous work we proposed, imple­
mented and experimented with a scheme, called destination
set grouping (DSG), where a source maintains a small num­
ber of video streams (say 3), carrying the same video but
each targeted at receivers with different capabilities. Each
stream is feedback­controlled within prescribed limits by its
group of receivers. Receivers may move among groups as
their capabilities or the capabilities of the network paths
leading to them change. In this paper we focus on the po­
tential for network overloading caused by the transmission
