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

69.08265412 milliseconds

Step-by-step 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=
`(0.058720256)/(1.7) =0.03454132706` seconds

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

or
`0.06908265412= 69.08265412` milliseconds
