public class MERGE
extends Protocol
implements Runnable
Periodically mcasts a HELLO message with its own address. When a HELLO message is received from a member that has the same group (UDP discards all messages with a group name different that our own), but is not currently in the group, a MERGE event is sent up the stack. The protocol starts working upon receiving a BECOME_SERVER event.
