Its simplicity and power has led to its becoming the single network protocol of choice in the world today. It connects many universities and government installations using leased telephone lines.

The most accurate name for the set of protocols is the "Internet protocol suite". TCP and IP are two of the protocols in this suite. The Internet is a collection of networks. Term "Internet" applies to this entire set of networks.

This layered representation leads to the term protocol stack, which refers to the stack of layers in the protocol suite.

By dividing the communication software into layers, the protocol stack allows for division of labor, ease of implementation and code testing, and the ability to develop alternative layer implementations.

Layers communicate with those above and below via concise interfaces. In this regard, a layer provides a service for the layer directly above it and makes use of services provided by the layer directly below it.

For example, the IP layer provides the ability to transfer data from one host to another without any guarantee to reliable delivery or duplicate suppression. A few provide "low- level" functions needed for many applications.

Others are protocols for doing specific tasks, e.

These machines had their own disks, and generally were self contained. An application is a user process cooperating with another process usually on a different host there is also a benefit to application communication within a single host. Transport Layer The transport layer provides the end-to-end data transfer by delivering data from an application to its remote peer.

Multiple applications can be supported simultaneously. The most-used transport layer protocol is the Transmission Control Protocol TCPwhich provides connection-oriented reliable data delivery, duplicate data suppression, congestion control, and flow control.

Another transport layer protocol is the User Datagram Protocol It provides connectionless, unreliable, best-effort service. As a result, applications using UDP as the transport protocol have to provide their own end-to-end integrity, flow control, and congestion control, if desired. Usually, UDP is used by applications that need a fast transport mechanism and can tolerate the loss of some data.

Internet Protocol IP is the most important protocol in this layer. It is a connectionless protocol that does not assume reliability from lower layers.

IP does not provide reliability, flow control, or error recovery.The original specification for the File Transfer Protocol was written by Abhay Bhushan and published as RFC on 16 April Until , FTP ran on NCP, the predecessor of TCP/IP. [2] The protocol was later replaced by a TCP/IP version, RFC (June ) and RFC (October ), the current specification.

TCP/IP means Transmission Control Protocol and Internet Protocol. It is the network model used in the current Internet architecture as well.

Protocols are set of rules which govern every possible communication over a network. "TCP/IP sockets in C# is an excellent book for anyone interested in writing network applications using initiativeblog.com frameworks. It is a unique combination of well written concise text and rich carefully selected set of working examples.

Serial Line Internet Protocol (SLIP) (Page 1 of 3) The need for a data link layer protocol to let IP operate over serial links was identified very early on in the development of TCP/IP.

x and Beyond! IEEE x has been leveraged for a long time for authentication purposes. Up until this point, little has been done to help researchers expose vulnerabilities within the systems that implement the protocol.
