Question:
Assume a communication media between Sender A and Receiver B has a Bandwidth of 2 Mbps
and the round trip delay between A and B is 20 ms.
a. If the system is using Stop and Wait Protocol determine the efficiency (Link Utilization
Percentage) of the system when each packet size is 1252 bits.
b. Suppose the packet size remains the same and we would like to maximize the efficiency (Link
Utilization Percentage) by using Go-Back-N Protocol. What would be the sliding window
size for both sender and receiver which will provide the maximum Link Utilization
Percentage? If the Transport layer header allows m bits for the sequence number, determine
the minimum number of bits (value of m) require for achieving this maximum Link
Utilization. And also find the sequence number range for this scenario.
c. Now, if the packet size is still the same and we would like to maximize the efficiency (Link
Utilization Percentage) by using Selective Repeat Protocol. What would be the sliding
window size for both sender and receiver which will provide the maximum Link Utilization
Percentage? If the Transport layer header allows m bits for the sequence number, determine
the minimum number of bits (value of m) require for achieving this maximum Link
Utilization. And also find the sequence number range for this scenario.
