GATE | GATE-CS-2017 (Set 1) | Question 47

The values of parameters for the Stop-and – Wait ARQ protocol are as given below.

Bit rate of the transmission channel = 1Mbps

Propagation delay from sender to receiver = 0.75 ms
 
Time to process a frame = 0.25ms
 
Number of bytes in the information frame = 1980
   
Number of bytes in the acknowledge frame = 20
 
Number of overhead bytes in the information frame = 20
