a. True or false: When traffic intensity ≤ 1, there will be no
queuing delay. Please also explain why.
b. For a given router R with a single outgoing link and infinite buffer, suppose
packet length is 1250 bytes and transmission rate of R's outgoing link is 10Mbps.
Calculate the average queuing delay for following packet arriving rates
i. One packet arrives every 1ms
ii. 10 packets arrive simultaneously every 10ms
iii. 100 packets arrive simultaneously every 100ms
