b) Consider a scenario where fragmentation may take place in packet transfer. Discuss how such fragmentation may be reassembled at the destination. Now consider in such scenario, a datagram is fragmented into five fragments. The first four fragments arrive, but the last one is delayed. Eventually, the timer goes off and the four fragments in the receiver’s memory are discarded. A little later, the last fragment arrives. What should be done with it?

Types Of Protocols

A network protocol is a collection of rules that governs the exchange of data between devices connected to the same network. In other words, network protocols are rules that specify how devices communicate or transfer data over a network. The sender and receiver systems must obey the standards to facilitate communication between them.
