Question 1) (35%) In a TCP stream there are 120 segments with each segment is 200 Bytes. The maximum transmission rate of the end to end system is measured 160 Kilo bit per second. End to end round trip delay is estimated as 70 milliseconds. a) If TCP is employed with static window size of 4 segments, what would be latency of transferring 120 segments? b) If TCP is employed with dynamic window size scheme with slow start mechanism, where maximum window size is 16 segments, and the window size grows exponentially until 8 segments, then grows linearly? c) What would be the throughput of TCP schemes in Parts A and B? d) Suppose every time the window size reaches 10, there is a problem with network, and TCP initiates slow start mechanism which forces window size to drop to 1, then the window size grows as explained in Part B, what would be the latency and throughput in this scenario? Question 2) (35%) For the given topology below please find the routing table for node A using Link State routing protocol. I B 3 2
