Which of the following functionalities must be implemented by a transport protocol over and above the network protocol?
-
- Recovery from packet losses
- Detection of duplicate packets
- Packet delivery in the correct order
- End to end connectivity Flow & Error Control & Switching Techniques
- Recovery from packet losses
Correct Option: D
The transport layer of TCP/IP model is very similar to the transport layer of OSI model. The transport layer is more commonly known as Host to Host protocol layer as it is responsible to setup and maintain (end to end communication) between two hosts. Hence, the transport protocols maintain the end to end connectivity.
