ABSTRACT
We describe a newscalable application-layermulticastprotocol, specif-
ically designed forlow-bandwidth, datastreaming applications with
large receiver sets. Our scheme is based upon a hierarchical cluster-
ing of the application-layer multicast peers and can support a num-
ber of different data delivery trees with desirable properties.
We present extensive simulations of both our protocol and the
Narada application-layer multicastprotocol overInternet-like topolo-
gies. Our results show that for groups of size 32 or more, our proto-
col has lower link stress (by about 25%), improved or similar end-
to-end latencies and similar failure recovery properties. More im-
portantly, it is able to achieve these results by using orders of mag-
nitude lower control traffic.
Finally, we present results from our wide-area testbed in which
we experimented with32-100 member groups distributedover 8dif-
ferent sites. In our experiments, averagegroup membersestablished
