Unformatted text preview: one right after the other. a) (5%) What is the time required to send one packet from A to the first router? b) (15%) What is the total time required to send the file from A to B? 8. (20%) There are 24 hosts sharing a communication line with a bandwidth of 9600 bps. Each host generates 10 packets per minute into the line. The length of a packet is exponentially distributed with an average of 2000 bits. The queueing delay can be calculated by the following formula: 1 T μ λ = − , where the average packet service rate is defined as / R L = , L is the average packet length, R represents the transmission rate of a packet over the communication line and denotes the average packet arrival rate. For each host, calculate the average queueing delay per packet when the communication line is allocated to the hosts by using: a) (10%) Statistical multiplexing; b) (10%) Time-division multiplexing (TDM). ----- END -----...
