Transport Layer

Transport layer receives the entire message from the application layer ( in TCP / IP model ) or from the session layer ( in ISO / OSI model).Transport layer divide the entire message into different transmittable segments. Also it add a header to each segment.It provides service point addressing ( delivery of a message to the appropriate application of a computer running many applications).The transport layer is responsible for process to process delivery of the entire message.Hence the transport layer is responsible for end to end communication
