JBoss Messaging uses JGroups for all group management. This contains the JGroups stack configuration for the data channel.

The data channel is used for sending sending/receiving messages from other nodes in the cluster.

The details of the JGroups configuration won't be discussed here since it is standard JGroups configuration. Detailed information on JGroups can be found in JGroups release documentation or on-line at http://www.jgroups.org or http://wiki.jboss.org/wiki/Wiki.jsp?page=JGroups.
