The protocols of this 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, which is the foundation of the Internet, and the OSI model of general networking are different . The protocols in use today in this layer for the Internet all originated in the development of TCP / IP . In the OSI model the transport layer is often referred to as Layer 4, or L4, while numbered layers are not used in TCP / IP . </P>
