Q. Comparing Transport for TCP/IP and osi model?
- The features of TCP and UDP defined at TCP/IP Transport Layer correspond to many of the requirements of the OSI Transport Layer.
- There is a bit of bleed over for needs in the session layer of OSI since sequence numbers and port values can help to permit the Operating System to keep track of sessions however most of the UDP and TCP functions and specifications map to the OSI Transport Layer.
- The TCP/IP as well as OSI architecture models both employ all connection and connectionless models at transport layer.
- Nevertheless the internet architecture refers to the two models in TCP/IP as simply -connections? and datagram.
- However the OSI reference model with its penchant for -precise? terminology utilizes the terms connection-mode and connection-oriented for the connection model and the term connectionless-mode for the connectionless model.
