Two peer processes A (sender) and B (receiver) use stop-and-wait ARQ to send packets
over a single link with capacity C. All packets have the same length of 100 bits. The
round-trip time (which is the time until A receives an acknowledgment for a sent packet)
is equal to 2 seconds. Assume that no packets or ACK’s are dropped and that all packets
and ACK’s arrive error-free. Furthermore, assume that the capacity C is equal to 100,000
bits per second.
(a) Find the average (transmission) rate (in bits per seconds) with which process A sends
data to process B?
(b) What is the link utilization?
