Question

Calculate the optimal window size when packet of 1000 bits and propagation delay of 250 ms is sent over a network with a bottleneck bandwidth of 50kbps

Answer 1

Compute approx optimal window size when packet size is 1000 bits and ...

propogation delay is 250msec and bottleneck bandwith is 50kbps ...


PT=propagation time


and TT=Transmission time ...


actually it's Bandwidth delay product..


(RTT*BW)/Data size = maximum # of packets that can be send in one go.
