Assume pipelining and 20 packets can be sent without ACK, 100 Mbps link, 10 ms propagation delay, 10,000 bit packet. Calculate sender utilization.
Homework Answers
ANSWER:
GIVEN THAT:
CALCULATING THE SENDER UTILIZATION:
1. Transmission delay (Tt) = length / bandwidth
= 10000/(100* 106)
= 0.0001 sec
= 0.1 ms
2. Propagation delay ( Tp) = 10 ms.
And number of packets(N) at a time given is 20.
Then a is (Tp/Tt) = 100
So, sender utilization / efficiency
= N / ( 1 + 2a)
= 20 / ( 1 + 2*100)
= 20/ 201
= 9.95 % efficiency

Host A is connected to Host B through a 100 Mbps link which has a propagation speed of 3 * 108 m/s, and the two hosts are 30 km apart. Assuming the network is not busy so that there are no processing or queueing delays, what is the end-to-end delay to send a 100 bit packet from Host A to Host B? (NOTE: Express your answer in milliseconds, i.e. msec and please show work.

3. Suppose there is exactly one packet switch (or router) between a sending host and a receiving host. The transmission rates between the sending host and the switch and between the switch and the receiving host are R1 = 1Mbps and R2 = 2Mbps, respectively. Assuming that the switch uses store-and-forward packet switching, what is the total end-to-end delay to send a packet of length 18000bits? Assume that the propagation speed is 2 * 108 meters/sec, the distance between source...

Assume a TCP sender is continuously sending 1,369-byte segment. If a TCP receiver advertises a window size of 7,001 bytes, and with a link transmission rate 34 Mbps an end-to-end propagation delay of 30.7 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. Give answer in percentages, rounded to one decimal place, without units (e.g. for an answer of 10.43% you would...

A company has a dedicated link of 100 Mbps. Each employee, when online, transmits continuously at 12 Mbps when active, but each user is active only 20 percent of the time. Assume packet switching is used. (a) What is the probability that more than 2 users are transmitting at the same time?
