Question:13 | ISBN:9780132856201 | Edition: 6

(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:

a. What is the average queuing delay for the *N *packets? Should this question not be "What is the queuing delay of the Nth packet? If so then this is (N-1)*L/R

b. What is the average queuing delay of a packet? The average queuing delay for 1 packet when we have N packets will be (N-1)*(L/(2R))

**Post the discussion to improve the above solution.**
