Tcp sigar class.
org.jgroups.protocols.TCP
TCP based protocol. Creates a server socket, which gives us the local address of this group member. For each accept() on the server socket, a new thread is created that listens on the socket. For each outgoing message m, if m.dest is in the ougoing hashtable, the associated socket will be reused to send message, otherwise a new socket is created and put in the hashtable. When a socket connection breaks or a member is removed from the group, the corresponding items in the incoming and outgoing hashtables will be removed as well.
This functionality is in ConnectionTable, which isT used by TCP. TCP sends messages using ct.send() and registers with the connection table to receive all incoming messages. @author Bela Ban
