Q. Focus of Reliability Control?
- Implementation of the OSI model puts emphasis on providing a reliable data transfer service while the TCP/IP model treats reliability as an end-to-end problem.
- Every layer of the OSI model detects and handles errors all data transmitted includes checksums. The transport layer of the OSI model checks source-to-destination reliability.
- In the TCP/IP model, reliability control is concentrated at the transport layer. The transport layer handles every error detection and recovery. The TCP/IP transport layer uses acknowledgments, checksums and timeouts to control transmissions and provides end-to-end verification.
