TLM 2.0 Sockets in UVM !!!

Normally the connection between two processes is through port and export , but with TLM 2.0 we have sockets which provide asynchronous pipelined bi directional connectivity between components. Socket has both a export and port packaged together. A socket can  be initiator socket or target socket. Data flows in the forward direction from the initiator socket to target socket , there is also a backward path between Target socket to initiator socket. TLM connectivity between components can be easily encapsulated using sockets.
