TCP/IP Protocols
From Network Dictionary Wiki
The TCP/IP protocol suite, or Internet protocol suite, is the set of communications protocols that implement the protocol stack on which the Internet and most commercial networks run. TCP/IP protocol suite is named after two of the most important protocols in it: the Transmission Control Protocol (TCP) and the Internet Protocol (IP), which were also the first two networking protocols defined. Today's IP networking represents a synthesis of two developments that began to evolve in the 1960s and 1970s, namely LANs (Local Area Networks) and the Internet, which, together with the invention of the World Wide Web by Tim Berners-Lee in 1989, have revolutionized computing.
The Internet Protocol suite—like many protocol suites—can be viewed as a set of layers. Each layer solves a set of problems involving the transmission of data, and provides a well-defined service to the upper layer protocols based on using services from some lower layers. Upper layers are logically closer to the user and deal with more abstract data, relying on lower layer protocols to translate data into forms that can eventually be physically transmitted. The TCP/IP reference model consists of four layers.
- Application Layer Protocols
- Presentation Layer Protocols
- Session Layer Protocol
- Transport Layer Protocols
- Routing Protocols Protocols
- Multicast Protocols
- MPLS Protocols
- Data Link Layer Protocols
