7) (12 pts) Consider a network where the sliding window protocol is in use with SWS = RWS = 2 frames and a one way delay of 100ms (i.e. for a frame sent at time t, it arrives at t + 100ms). Assume that when multiple frames are all able to be sent according to the window size, that they are sent 20ms apart (i.e., frame 1 starts at time t, and frame 2 starts at time t + 20ms). a) (4 pts) What would be a reasonable timeout value for this link? Why not something smaller? How about larger? b) (4 pts) Can the selection of window size (i.e., SWS-RWS=2) fully utilized the link? If yes, please explain. If not, what is the channel utilization efficiency? c) (4 pts) Now, assume that by sending a frame every 5ms we can saturate the link. In this case, determine the smallest SWS and RWS that maximizes throughput (i.e., keeps the pipe full). 7) (12 pts) Consider a network where the sliding window protocol is in use with SWS = RWS = 2 frames and a one way delay of 100ms (i.e. for a frame sent at time t, it arrives at t + 100ms).
