Consider that packets arrive at an internet router from 3 different other routers, each with Poisson arrivals with l = 4 per second. The packets are all transmitted on the same transmission line. It is assumed that the packets have fixed lengths and are all equal, and that the transmission rate for the transmission line is fixed . Assume a transmission rate on the transmission line of m = 16 packets per second.
Compute the transmission line utilization and answer whether this is a stable queue.
