Consider a satellite communication link with a one way propagation delay of 300ms between the sender and receiver, operating at 50 Mbps using packets of length 5000 bytes. Length of the piggybacked ACK packet is also 5000 bytes.

a) What is the minimum timeout period required for the Stop-and-Wait protocol? The timer is set when the last bit is transmitted.

b) What is the maximum effective data rate of the link for this protocol?

c) Find the minimum window size with which Go-Back-N would be able to achieve 100% efficiency in the absence of any errors.

d) Find the data rate that can be achieved with Stop & Wait, Go-Back-N and selective repeat, if the frame error rate is 10^-2?
