Answer Posted / chaitanya poloju
WebLogic Server instances in a cluster communicate with one
another using two basic network technologies:
o IP sockets, which are the conduits for
peer-to-peer communication between clustered server instances.
o IP unicast or multicast, which server instances
use to broadcast availability of services and heartbeats
that indicate continued availability.
Note: When creating a new cluster, it is
recommended that you use unicast for messaging within a
cluster. For backward compatibility with previous versions,
WebLogic Server you must use multicast for communications
between clusters.
