Detailed Description

Author:

Adriana Danes

The discovery service creates and starts at least a DiscoveryManager which is a MBean that multicasts discovery information to all the servers who joined the discovery multicast group.

The discovery service may also create a Enroller and a DiscoveryClient, and in this case the current server becomes a discovery server.

Discovery information contains information allowing to remotely manage a server in the group.

Discovery multicast group is a group of servers which can be managed remotely by a discovery server.

Discovery server is the server in the group who detains the discovery information concerning all the servers in the group.
