Suppose there are 93 packets entering a queue at the same time. Each packet is of size 4 MiB. The link transmission rate is 1.4 Gbps. What is the queueing delay of packet number 46

0.19s

Explanation:

Queueing delay is the time a job waits in a queue before it can be executed. it is the difference in time betwen when the packet data reaches it destination and the time when it was executed.

Queueing delay = (N-1) L / 2R

where N = no of packet = 93

L = size of packet = 4MB

R = bandwidth = 1.4Gbps = 1*10⁹ bps

4 MB = 4194304 Bytes

(93 - 1) 4194304 / 2 * 10⁹

queueing delay = 192937984 * 10⁻⁹

=0.19s
