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 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.
WTLS adapts that design to be more appropriate on a packet based network. A significant amount of the design is based on a requirement that it be possible to use a packet network such as SMS as a data transport. WTLS has been superseded in the WAP Wireless Application Protocol 2.0 standard by the End-to-end Transport Layer Security Specification.
HTTP Strict Transport Security (HSTS) is a policy mechanism that helps to protect websites against man-in-the-middle attacks such as protocol downgrade attacks [1] and cookie hijacking. It allows web servers to declare that web browsers (or other complying user agents ) should automatically interact with it using only HTTPS connections, which ...
In computer networking, the Transport Layer Interface (TLI) was the networking API provided by AT&T UNIX System V Release 3 (SVR3) in 1987 [1] and continued into Release 4 (SVR4). [2] TLI was the System V counterpart to the BSD sockets programming interface, which was also provided in UNIX System V Release 4 (SVR4). [ 2 ]
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 ...
