Question

CONSIDER A WINDOW SIZE IS 10, bandwidth is 1500 bps transmission delay is 2ms and propagation delay is 50ms what is throughput using GO back N protocol

Answer 1

Answer:

294.1

Explanation:

Throughput  = Efficiency x Bandwidth

Efficiency (η)  = N / (1+2a)

Transmission delay (Tt)  = 2ms

a = Tp / Tt = 50ms / 2 ms = 25

Efficiency (η)  = N / (1+2a)  = 10 /(1 + 2 x 25) = 10/51

Throughput  = 10/51  x  1500 = 294.1
