Find the link utilization in stop and wait protocol if the bandwidth of the line 2 kbps, round trip time is 20 second and the packet size is 2000 bytes.
Bandwidth-delay product =2×10^3×20=40000
But the system is sending only 2000*8=160000 bits
so, Link utilisation is (40000/160000)×100=25%
given ans is different .
please correct me
