Question

Suppose there are 69 packets entering a queue at the same time. Each packet is of size 7 MiB. The link transmission rate is 1.7 Gbps. What is the queueing delay of packet number 3?

Answer 1

Answer:

69.08265412 milliseconds

Explanation:

Lets first convert 7 MiB to bits

$7*1024*1024*8=58720256$ bits

Now convert bits to Gbits

$58720256/10^{9} =0.058720256$ Gbits

Queuing Delay = Total size/transmission link rate

Queuing Delay= $\frac{0.058720256}{1.7} =0.03454132706$ seconds

Delay of packet number 3 = $0.03454132706*2=0.06908265412$ seconds

or $0.06908265412= 69.08265412$ milliseconds
