IP Datagram Fragmentation
•Each fragment (packet) has the same structure as the IP datagram.
•IP specifies that datagram reassembly is done only at the destination (not on a hop-by-hop basis).
•If any of the fragments are lost - the entire datagram is discarded (and an ICMP message is sent to the sender).
