JGroups is a reliable group communication toolkit written entirely in Java. It is based on IP multicast (although TCP can also be used as transport), but extends it with... JGroups extends reliable unicast (one-to-one) message transmission (like in TCP) to multicast (one-to-many) settings. As described above it provides reliability and group membership on top of IP Multicast. Since every application has different reliability needs, JGroups provides a flexible protocol stack architecture that allows users to put together custom-tailored stacks, ranging from unreliable but fast to highly reliable but slower stacks.
