Abstract-- When many parties share network resources on an
overlay network, mechanisms must exist to allocate the resources
and protect the network from overload. Compared to large
physical networks such as the Internet, in overlay networks the
dimensions of the task are smaller, so new and possibly more
effective techniques can be used. In this work we take a fresh
look at the problem of flow control in multi-sender multi-group
reliable multicast and unicast and explore a cost-benefit approach
that works in conjunction with Internet standard protocols such
as TCP.
In contrast to existing window-based flow control schemes we
avoid end-to-end per sender or per group feedback by looking
only at the state of the virtual links between participating nodes.
This produces control traffic proportional only to the number of
overlay network links and independent of the number of groups,
senders or receivers. We show the effectiveness of the resulting
