If each computer broadcasted at the same time, there may be a jam at the transport layer. Process to process delivery or the port to port delivery is dealt in the transport layer. Submit Message. To achieve this goal, the transport layer makes use of the services provided by the network layer. In internet protocol suite, the application layer contains communication protocols and interface methods which used for the process to process communication . UDP and TCP perform the demultiplexing and multiplexing jobs by including two special fields in the segment headers: the source port number field and the destination port number field. It was the first standard model for network communications, adopted by all major computer and telecommunication companies in the early 1980s.
