A note on the stability of multiclass Markovian queueing networks

In this paper we show that in a multiclass Markovian network with unit rate servers, the condition that the average load $ρ$ at every server is less than unity is indeed sufficient for the stability or positive recurrence for \emph{any} work conserving scheduling policy and \emph{class-independent} routing. We use a variation of the positive recurrence criterion for multidimensional discrete-time Markov chains over countable state spaces due to Rosberg (JAP, Vol.~17, No.~3, 1980) and a monotonicity argument to establish this assertion.
