Considering all the packets in the file, draw a message sequence diagram that illustrates the packets. A message sequence diagram uses vertical lines to represent events that happen at a computer over time (time is increasing as the line goes down).
Addresses of the computers/software are given at the top of the vertical lines. Horizontal or sloped arrows are used to show messages (packets) being sent between computers. Each arrow should be labelled with the protocol, packet type and important information of the message. An example of a portion of the message sequence diagram for packets
