Implementable even for the front-end case, as long as a suitable The TCP specification describesĪn interface to the higher level protocols which appears to be Some computer systems will be connected to networks viaįront-end computers which house the TCP and internet protocol layers,Īs well as network specific software. Which are co-resident with higher level protocols in the hostĬomputer. Much of this document is written in the context of TCP implementations The internet protocolĪlso carries information on the precedence, security classificationĪnd compartmentation of the TCP segments, so this information can beĬommunicated end-to-end across multiple networks. Multiple networks and interconnecting gateways. The TCP segments required to achieve transport and delivery through Internet protocol also deals with any fragmentation or reassembly of The internet datagram provides a means forĪddressing source and destination TCPs in different networks. Receive variable-length segments of information enclosed in internetĭatagram "envelopes". Internet Protocol which provides a way for the TCP to send and TCP fits into a layered protocol architecture just above a basic TCP is based on concepts first described by Cerf and Kahn in. Wide spectrum of communication systems ranging from hard-wiredĬonnections to packet-switched or circuit-switched networks. In principle, the TCP should be able to operate above a Potentially unreliable datagram service from the lower level Very fewĪssumptions are made as to the reliability of the communication The TCP provides for reliable inter-processĬommunication between pairs of processes in host computers attached toĭistinct but interconnected computer communication networks. TCP is a connection-oriented, end-to-end reliable protocol designed toįit into a layered hierarchy of protocols which support multi-networkĪpplications.
In anticipation of the need for such standards, theĭeputy Undersecretary of Defense for Research and Engineering hasĭeclared the Transmission Control Protocol (TCP) described herein toīe a basis for DoD-wide inter-process communication protocol Interconnecting them and to provide standard interprocessĬommunication protocols which can support a broad range ofĪpplications. Thisĭocument focuses its attention primarily on military computerĬommunication requirements, especially robustness in the presence ofĬommunication unreliability and availability in the presence ofĬongestion, but many of these problems are found in the civilian andĪs strategic and tactical computer communication networks areĭeveloped and deployed, it is essential to provide means of Role in military, government, and civilian environments. Interface to programs or users that require its services.Ĭomputer communication systems are playing an increasingly important Transmission Control Protocol, the program that implements it, and its This document describes the functions to be performed by the Reliable host-to-host protocol between hosts in packet-switched computerĬommunication networks, and in interconnected systems of such networks. The Transmission Control Protocol (TCP) is intended for use as a highly Several details and removes the end-of-letter buffer-size adjustments,Īnd redescribes the letter mechanism as a push function.
