*
* This class provides an abstract interface and holds minimal info
* on which the Transport Caching scheme is based on. Concrete
* connection properties can be got by inheriting from this class and
* implementing the virtual functions.
* Note 1: Additional properties for connection like Qos,
* Priority that the RT folks would need, can be added by
* inheriting from this class and providing the following
* methods.
* 1. duplicate ()
* 2. is_equivalent ()
* 3. hash ()
