Abstract
Embodiments of the invention make the underlying transport mechanism transparent to the sender and/or receiver. Using embodiments of the invention, it is not necessary for a sender or receiver to interface with the transport mechanism. Messages are received in a single format which eliminates the need for the sender or receiver to accommodate multiple message formats. A socket mechanism implements bi-directional transmissions and acts as a buffer between the sender or receiver and the underlying transport mechanism. The socket mechanism interfaces with a transport delivery mechanism that receives packets from the physical network. The socket forwards messages received from the transport delivery mechanism to a message processor. Further, the socket forwards messages from the message processor to the transport delivery mechanism. The transport deliver mechanism removes a transport header of messages received from and adds a transport header to messages sent to the physical network.
