本文提出并分析了一类具有两层结构的嵌入式网络，以便为计算机和/或通信系统的性能分析提供结构良好的网络层次模型。上层描述经常被忽视的软件行为，而下层描述通常的硬件行为。对于上层不包含未完成队列的情况，假设状态依赖的到达率和状态依赖的服务率函数具有一般的服务时间分布，建立了一个乘积型均衡联合分布.为了便于应用，还导出了边际分布.对于上层包含未完成队列的情况，提出了一种近似方法，推广了流等价方法。
A family of queueing networks with a two-layer configuration is proposed and analyzed in order to provide well structured hierarchy of network models for performance analysis of computer and/or communication systems. The upper layer describes the often-disregarded software behavior while the lower layer describes the usual hardware behavior. For the case in which the upper layer includes no outstanding queues, a product form equilibrium joint distribution is established assuming state-dependent arrival and state-dependent service rate functions with general service time distributions. The marginal distributions are derived for convenience in applying the results. For the case in which the upper layer dose include outstanding queues, an approximation method is proposed, which generalizes the flow-equivalent methods.
