A family Qf queueing networks with a two-layer configuration is proposed and analyzed in order to provide well structured hierarchy of network models for performance analysis ef computer andlor communication systems. The upper layer describes the often-disregarded software behavior while the lower 1ayer descrlbes the usual hardwame behavior, Fbr the case in which the upper layer includes no outstanding queues, a product form equilibriumjoint distribution is established assuming state-dependent
