What do you mean by failover?

JGroups provides clustering, ie. discovering and joining a cluster, =

sending messages between members of a cluster and getting notifications =

when members join or leave (or crash).

This could be used for example to provide multiple JBoss Fuse servers, =

that possibly even share state.

Failover, however, in my opinion, is something between clients and a =

server: when the server dies (or leaves the cluster), clients are =

notified and re-connect ('fail over') to a surviving server.

Infinispan, for instance, has a client-server protocol (HotRod) which =

includes the list of servers, so that clients can failover to another =

server should the server they're connected to fail.
