Use ping command to generate IP (ICMP) packets.

Conduct Q1 and Q2 in two conditions in which two end PCs are in (A) a same datalink and (B) different datalinks (e.g., PC1 in lab A and PC2 in lab B)

Capture all frames in both end PCs while sending/receiving ICMP packets to/from someone in your group. If you are a sender, execute ping [destination IP]. Otherwise, do nothing because OS automatically replies to ICMP.

  1. Draw time-sequence diagrams for receptions/transmissions of both frames and packets with its header information for two cases, (A) and (B), and explain what each frame/packet was for
    • You must clear the arp cache by executing arp -d -a at both end PCs immediately before ping
  2. Explain your understanding of how the Internet can deliver packets to a destination (by yourself)
