JGroups is a library for reliable one-to-one or one-to-many communication written in the Java language.

It can be used to create groups of processes whose members send messages to each other. JGroups enables developers to create reliable multipoint (multicast) applications where reliability is a deployment issue. JGroups also relieves the application developer from implementing this logic themselves. This saves significant development time and allows for the application to be deployed in different environments without having to change code.
