Answer / 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.

Unicast:unicast mode communication is all manager servers
are divided into "N" number of categiries is called Unicast
mode communication.
Each and every group, one group leader is identified. All
other manager servers update status information, Particular
group has the update status information is available that
perticular group leader.
Multicast:Multicast mode of the communication is many to
many communication having. each and every manager server
will receive the hert beat signal to other manager server.
Heart beat is nothing but it is a multicast address
and the port number along with the manager server name.
