The protocols of the transport layer provide host - to - host communication services for applications . It provides services such as connection - oriented communication, reliability, flow control, and multiplexing . </P> <P> The details of implementation and semantics of the Transport Layer of the TCP / IP model (RFC 1122), which is the foundation of the Internet, and the Open Systems Interconnection (OSI) model of general networking, are easily compared . In the OSI model the transport layer is most often referred to as Layer 4 or L4, while numbered layers are not used in TCP / IP . </P>
