Detailed Description

IPv4 Raw Socket Fragmentation Test Configuration : Two sockets.

1 sender, 1 receiver Sender socket sends packets in two epochs. In the first epoch, it sends payload of sizes {500, 1000, 5000, 10000, 20000, 40000, 60000}. In the second epoch, it sends payload of sizes {5000, 10000, 20000, 40000, 60000}. These are payloads of size greater than the MTU of the link. In the first epoch, there is no loss model. In the second epoch, the second fragment of the packet sent is dropped.

Expected behaviour: In the first epoch: Receiver should receive only 1 packet and the size of the payload received should be equal to the size of the payload sent. No packets should have been dropped. In the second epoch: Receiver should not receive any packet. Only 1 packet should have been dropped at the physical layer.
