 * This abstract class defines a Transport advertisement. Each peer endpoint
 * protocol is associated with a transport advertisement that describes the
 * protocol and network interface associated with the endpoint transport. For
 * example for TCP endpoint. the following transport information needs to be
 * maintained for this endpoint:
 * 
 * 
Transport :
 * 

 * Protocol : TCP
 * 
Port : 6001
 * 
MulticastAddr : 224.0.1.85
 * 
MulticastPort : 1234
 * 
MulticastSize : 8192
 * 
 * 
 * 
This class is an abstract class that needs to be extended by implementation
 * to support the different types of transport advertisements (TCP, HTTP, etc)
