Java Reliable Multicast (JRM) Service can be used
by information distribution applications as the
transport for delivery of content to very large
constituencies. As compared to unicast protocols
(i.e., HTTP), reliable multicast enables
broadcasting to groups of receivers, ensuring
bandwidth conservation and timely delivery. TRAM,
a reliable multicast transport protocol developed
along with the JRM Service, is designed for high
scalability, targeted at very large numbers of
receivers. The JRM Service includes new services
for multicast address allocation and management
of channels, as well as a dynamic filtering
mechanism that uses Java software classes which
are pushed into the network for the purpose of
interpreting the data downstream from the server.
