1) Assume a TCP sender is continuously sending 1162-byte segment. If a TCP receiver advertises a window size of 7873 bytes, and with a link transmission rate 23 Mbps an end-to-end propagation delay of 32 ms, what is the utilization? Assume no errors, no processing or queueing delay, and ACKs transmit instantly. Also assume the sender will not transmit a non-full segment.

2) Given a nodal delay of 62.9ms when there is no traffic on the network (i. e. usage = 0%), what is the effective delay when network usage = 83.7% ?

3) Given a effective delay of 27ms when network usage is 97%, what is the effective delay when network usage = 31% ?
