Abstract
Efficient multicast communication provides one of the best avenues for
scaling bandwidth intensive applications. Current multicast
routing mechanisms perform well for multicast groups which reach a
long-term, steady-state distribution of membership. However, when
the membership migrates throughout the network, current routing
techniques may perform poorly. One type of multicast routing
technique involves selection of a "core" router through which all multicast
communication is routed. We propose to adapt this routing scheme
to efficiently support dynamic groups, by allowing the core to migrate.
As part of our work we provide solutions to several problems that are
more general, including estimating multicast bandwidth using unicast
information and soliciting responses from a limited number of participants
to avoid message implosion.
