The TCP/IP network architecture, also known as the Internet architecture, comprises two fundamental protocols: the Transmission Control Protocol (TCP) at the transport layer and the Internet Protocol (IP) at the network layer. These protocols originated from the ARPANET, an early packet-switching network funded by the Department of Defense.
The TCP/IP network architecture, also known as the Internet architecture, consists of two fundamental protocols: the Transmission Control Protocol (TCP) at the transport layer and the Internet Protocol (IP) at the network layer. These protocols trace their origins back to the ARPANET, an early packet-switching network funded by the Department of Defense. The TCP/IP network architecture has played a central role in the development of various networking technologies and applications.
Key Points of TCP/IP Network
- TCP and IP Evolution:
- TCP and IP evolved from the ARPANET, shaping the foundation of the TCP/IP network architecture.
- Layer Structure:
- The TCP/IP network architecture aligns with the OSI reference model and consists of five layers.
- Networking Technologies and Applications:
- The TCP/IP network has been pivotal in the development of various networking technologies and applications.
- Examples include Voice over IP (VOIP) and Video Conference applications using MBONE.
- Applications Running on TCP/IP:
- Various network protocols and applications operate on top of the TCP/IP protocol.
- Layers of the TCP/IP Network:
- Figure 1 illustrates the layers of the TCP/IP network and highlights some applications that may exist within this architecture.
- Standardization:
- The Internet Engineering Task Force (IETF) is the standard organization for TCP/IP-related standards.
- It issues Request-for-Comment (RFC) documents, and IETF requires a prototype implementation before submitting an RFC for comments.
Numerous network protocols and applications operate on top of the TCP/IP protocol stack. Examples include Voice over IP (VOIP) and Video Conferencing applications using MBONE. The TCP/IP network architecture aligns with the five layers defined in the OSI reference model.
The Internet Engineering Task Force (IETF) is the standard organization responsible for TCP/IP-related standards. It issues Request-for-Comment (RFC) documents, which serve as important documents defining standards and protocols. Notably, the IETF typically requires that a prototype implementation be completed before an RFC can be submitted for comments, ensuring practicality and functionality.
