Question: Consider a queuing system with one server, and consider that this server serves packets following an exponential service time with mean E[T] = 2 seconds.
Packets arrive with a Poisson distribution with mean l = 0.25 packets per second?
Part 1: What queue model is this?
Part 2: Is the system stable?
Part 3: What is the total delay experienced by a customer in this system, from the moment it arrives until it is served?
Part 4: Assuming now that the arrival rate doubles at evening hours, what is the new total delay experienced by the packets in this system?
