JGroups is a toolkit for reliable multicast communication that can be used to create groups of processes whose members can send messages to each other. JGroups is the distributed framework basis for JBoss Application Server's advanced clustering and failover features. JGroups allows developers to create reliable multipoint (multicast) applications where reliability is a deployment issue, and does not have to be implemented by the application developer. This saves application developers significant amounts of time, and allows for the application to be deployed in different environments, without having to change code
