The Internet protocol suite, commonly known as TCP/IP, is a framework for organizing the set of communication protocols used in the Internet and similar computer networks according to functional criteria.
The Internet protocol suite is therefore often referred to as TCP/IP. The first major version of IP, Internet Protocol version 4 (IPv4), is the dominant protocol of the Internet. Its successor is Internet Protocol version 6 (IPv6), which has been in increasing deployment on the public Internet since around 2006.
This is a list of the IP protocol numbers found in the field Protocol of the IPv4 header and the Next Header field of the IPv6 header. It is an identifier for the encapsulated protocol and determines the layout of the data that immediately follows the header. Both fields are eight bits wide.
An application layer is an abstraction layer that specifies the shared communication protocols and interface methods used by hosts in a communications network. [1] An application layer abstraction is specified in both the Internet Protocol Suite (TCP/IP) and the OSI model. [2]
In version 4, the monolithic Transmission Control Program was divided into a modular architecture consisting of the Transmission Control Protocol and the Internet Protocol. [ 5 ] [ 6 ] This resulted in a networking model that became known informally as TCP/IP , although formally it was variously referred to as the DoD internet architecture ...
This article lists protocols, categorized by the nearest layer in the Open Systems Interconnection model.This list is not exclusive to only the OSI protocol family.Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP) and other models and they often do not fit neatly into OSI layers.
Once the concept of a hierarchy of protocols had been accepted, and once TCP, IP, and X.25 had been assigned to different layers in this hierarchy, it became easier to think of them as complementary parts of a single system, and more difficult to view X.25 and the Internet protocols as distinct and competing systems."
HTTP (Hypertext Transfer Protocol) is an application layer protocol in the Internet protocol suite model for distributed, collaborative, hypermedia information systems. [1] HTTP is the foundation of data communication for the World Wide Web , where hypertext documents include hyperlinks to other resources that the user can easily access, for ...
