A stream of packets travel along a path with 10 links and nodes in the Internet. Each link is 100 km long and of 45 Mbps capacity, and has a propagation speed of 2 × 10⁸
m/sec. Assume no flow control, no other traffic along the path, and the source pumps packets at wire speed.

a. What is the number of bits contained in each link?

 b. If the average latency through each node is 5 ms, what is the average number of bits contained in each node?

 c. How many bits on the average are contained in the path?
