Birth-and-Death Queuing Systems 1. m parallel, identical servers 2. Infinite queue capacity 3. Whenever n users are in system(in queue plus in service) arrivals are Poisson at rate of mn per unit of time 4. Whenever n users are in system, service completions are Poisson at rate of un per unit of time 5. FCFS disciplineBirth-and-Death Queuing Systems 1. m parallel, identical servers. 2.
