          Hi,

           

          In JBoss/Wildfly you can create clusters either using UDP or TCP protocol.

           

          UDP protocol uses a broadcasting mechanism(e.g. Radio) which would broadcast the message to all the nodes in a UDP cluster.

          In case of TCP cluster, only the defined node will create a cluster. For .e.g You have to define IP:PORT in your configuration and then the communication will take place only between the defined servers.

           

          The main advantage of using UDP clustering is, you can add other nodes/servers dynamically in the cluster. Make sure your multicast network is properly configured.

           

          For more information, please refer High Availability Guide

            Well, with the default configuration using Infinispan's distribution cache mode and number of owners set to 2, there is very little benefit to using multicasting.
