Algorithm for Computing Steady-State Probabilities of the Queuing System with Hysteretic Congestion Control and Working Vacations

Resumo

This paper is devoted to investigation of a SIP congestion behavior under overload. The hysteretic overload control mechanism is considered to avoid SIP server collapse and also server working vacations was taken into account. In the paper a queuing model is introduced. The algorithm for computing steady-state probabilities is derived.
