A message is split into five packets. The first, the third and the last packet have 100 bytes. The second packet has 200 bytes and the fourth packet has 400 bytes. Draw a timing diagram for the first three hops, i.e., the host to the first router, the first router to the second router and the second router to the third router. All the routers are store-and-forward. Hint: draw the lengths of the packets carefully and pay attention to where bubbles should be inserted.
