Hello all, I'm reading this (http://wps.pearsoned.com/ecs_kurose_compnetw_6/) networking book. The exercise no 13 of chapter one says: P13. (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? I've obtained these for (a) and (b): (a): (N-1)/2 L/R sec. (b): For nth LN/R: [n(N-1)-2(n-1)]/2 L/R sec. 1- Are these answers correct? 2- Is here a correct place for posting such problems?
