Q4: What is the total delay (latency) for a frame of size 6 million bits that is being sent on a link with 5 routers each having a queuing time of 5 µs and a processing time of 2 us. The length of the link is 3000 Km. The speed of light inside the link is 2 x 10^8 m/s. The link has a bandwidth of 10 Mbps. Which component of the total delay is dominant? Which one is negligible?
