A buffer is filled over a single input channel and emptied by a channel with capacity of 1 Mbps. Measurements are made in the steady state for this system with the following results: Average number of packets stored in the buffer = 1 packet Average residence time/packet = 0.005 seconds Average packet length = 1000 bits The distributions of the arrival and service processes are unknown and cannot be assumed to be exponential! Find the average arrival rate in units of packets/second and the average number of packets r resident in the system.
