(i) Suppose that frames are 1250 bytes long including 25 bytes of overhead. Also assume that ACK frames are 25 bytes long.
a) Calculate the efficiency of stop-and-wait ARQ in a system that transmits at R=1 Mbps and reaction time 2(Tprop + Tproc) of the following: 1ms, 10ms, 100ms, and 1 second.
b) Repeat if R=1 Gbps.
(ii) Please discuss what options does an ARQ protocol have when it detects a frame with errors?
(iii) In a Stop-and-Wait ARQ system, the bandwidth of the line is 1 Mbps, and 1 bit takes 20 ms to make a round trip.
a) What is the bandwidth-delay product?
b) If the system data frames are 1000 bits in length, what is the utilization percentage of the link?
c) What is the utilization percentage of the link if the link uses Go-Back-N ARQ with a 15-frame sequence?
