(a) Suppose *N *packets arrive simultaneously to a link at which no packets are currently being

transmitted or queued.Each packet is of length *L *and the link has transmission rate *R*. What is

the average queuing delay for the *N *packets?

(b) Now suppose that *N *such packets arrive to the link every *LN/R *seconds.

What is the average queuing delay of a packet?

Calculate the average queuing delay:
