Problem
Two packet streams arrive at a node with rates 1M packets/sec (Stream 1) and 1.55M packets/sec (Stream 2), respectively. They are then sent to two transmission lines with different capacity. The average number of packets at the node from Stream 1 is 200. The average delay of a packet from Stream 2 at the node is 1.55 mili-second.
I. What is the total arrival rate from both streams?
II. Calculate the average delay of a packet at the node from Stream 1.
III. How many packets from Stream 2 are there at the node on the average?
IV. What is the total number of packets at the node from both Stream 1 and Stream 2?
V. What is the average delay of a packet at the node?
