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, [2] while numbered layers are not used in TCP/IP. The best-known transport protocol of the Internet protocol suite is the Transmission Control Protocol (TCP).
The transport layer performs host-to-host communications on either the local network or remote networks separated by routers. [50] It provides a channel for the communication needs of applications. UDP is the basic transport layer protocol, providing an unreliable connectionless datagram service. The Transmission Control Protocol provides flow ...
The X/Open Transport Interface is a specification that defines an independent transport-service interface for network applications. Programs using XTI can be run over a variety of transport providers, such as the Transmission Control Protocol (TCP), Xerox Network Systems (XNS), Systems Network Architecture (SNA), X.25, Asynchronous Transfer Mode (ATM) or any other transport layer provider that ...
The Internet application layer maps to the OSI application layer, presentation layer, and most of the session layer. The TCP/IP transport layer maps to the graceful close function of the OSI session layer as well as the OSI transport layer. The internet layer performs functions as those in a subset of the OSI network layer.
The transport layer transfers data between source and destination processes. Generally, two connection modes are recognized, connection-oriented or connectionless. Connection-oriented service establishes a dedicated virtual circuit and offers various grades of guaranteed delivery, ensuring that data received is identical to data transmitted.
