Question

Consider a router connecting an input link to an output link. This router has a buffer where it can store packets that are waiting to be transmitted on the output link.

After monitoring this router for some time, it was found that:

  • packets arrive to the router on average at a rate of 400 packets/sec
  • there is on average 50 packets in the router including the packet being transmitted.
  • the average time a packet spends in the buffer is 100 msec

 

  1. a) What is the average total delay experienced by a packet in this system, assuming there's no packet loss?

 

  1. b) What is the output link transmission rate in packets/sec?
