Eight data terminals statistically share the capacity of an outgoing link. Traffic is combined from the eight terminals and then served first-come first served. An (M/M/1) queue with infinite buffer is assumed. Find the expected number of packets in the buffer and the expected waiting time in the following cases:

a) A terminal generates a packet every 10seconds, the link speed is 1024 bits/sec, and packet length=512 bits

b) Repeat (a) using finite buffer k=10 and compare your results to the infinite buffer case
