The transport layer is the basic end-to-end building block of the Internet (TCP/IP) architecture and communications. Protocols above the transport layer concentrate on distributed applications processing, and protocols below the transport layer concentrate on the transmission, routing, and forwarding of application data. The transmission control protocol is a connection-oriented, reliable, byte stream service that provides data transfer that is reliable, ordered, fully duplex, robust, and flow controlled (Network Sorcery, n.d.; Rey, 1981)

Each TCP segment (shown in Figure 1) contains the source and destination port number to identify the sending and receiving application. A socket ...
