Assume that a source sends a message containing 8 packets to the destination and
there are 4 routers on the path. Assume the bandwidth of each link is 200 Mbps, and the size of
each packet is 16 Kb. Assume the length of each link is 20 kilometers, and the propagation speed is
2 x 108 meters per second. Assume each router begins retransmitting a packet after it has finished
receiving the packet and processed it for 4 microseconds (dproc = 4 µs). There is no queueing delay.
Calculate the end-to-end delay to this message (from first bit sent to the last bit received).

1. Host A and Host B are connected by a network with 2 store-and-forward switches. Each link has a bandwidth of 5 megabits/second and is 1,000 kilometers long. The network propagation speed is 200,000 kilometers/second. Host A sends 10,000-bit packets to Host B. Give proper units on each answer. (For these and other numerical problems it is required that you give a formula, using numbers from the problem, that can be evaluated to give the numerical answer.) a) What is...

An 8850-byte message is split into 10 packets where each packet is encapsulated with a 20-byte header and no trailer. If it takes 70 hops to reach the destination, what is the message transmission time? Assume it takes 1 ns to transmit 1 byte of data. Also assume all switches and routers in the network are store-and-forward. • Show your work.
