JGroups is a Java networking library that supports reliable group communication over UDP (IP Multicast) or TCP.

JGroups is a toolkit for reliable messaging. It can be used to create clusters whose nodes can send messages to each other.

The most powerful feature of JGroups is its flexible protocol stack, which allows developers to adapt it to exactly match their application requirements and network characteristics.

JGroups comes with a large number of protocols, for example:

  • Transport protocols: (IP Multicast) or
  • Fragmentation of large messages
  • Reliable unicast and multicast message transmission
  • Failure detection: crashed nodes are excluded from the membership
  • Flow control to prevent slow receivers to get overrun by fast senders
  • Ordering protocols: FIFO, Total Order
  • Membership
  • Encryption
  • Compression
