comment Two stage cyclic queue
is it that if i can actually draw out the state transition diagram it will be proved that it can be modeled as a BD process?

ermm. there wont be cases in which N =0 or $N=n because if N=0 the next state may be N-1 which is 0-1 which is wrong, since this is wrong the other state cannot be n as well? the transition rate is actually the service rate of the two servers?

oh so server B could end serving one of its customers first, in which case (N,n-N) is replaced by (N+1,n-N-1)? Am i correct? What do you mean when N = ___ or ___? the rate is dependent on the service rate of b for the second question?

comment Two stage cyclic queue
hmm i dont really understand. if its a closed system, there will be N customers at server A and n-N at server B, so after that server A will be processing the N+1 customer and n-N+1 customer at server B. is this what you are referring to?

events that can happen next will be that the arrival rate of server B will be service rate of server A and arrival rate of server A will be service rate of server B? So the time taken will be dependent on the arrival rate? State after tt time will be (n-N, N)? Still a bit confused by what it is asking for though.
