Relationship Between OSI model and TCP/IP protocol

The correspondence between the OSI model and the TCP/IP protocol the layers of popular TCP/IP protocols are not divided by the OSI reference model, but have a general correspondence with them. Network layer protocols mainly include the IP protocol to encapsulate and send IP packets. Grouping routing and avoiding blocking are the key design issues here. The Transport Layer defines two end-to-end protocols: Transport Control Protocol TCP and User Datagram Protocol UDP. Www.2cto.com TCP/IP does not involve the Session Layer and presentation layer. The application layer contains all high-level protocols, such as virtual terminal protocol Telnet, file transfer protocol FTP, and e-mail protocol SMTP. Also, NOVELL's SPX/IPX protocols are provided for reference. Network Layer ------- IP Protocol Transmission Layer ----- TCP (Transmission Control Protocol) and User Datagram Protocol UDP.
