除了技术因素以外,价格因素也会对网络的服务质量(QoS)产生较大的影响,根据排队论方法和经济学理论,假设价格的变化量与网络用户请求接入的变化量是确定关系,结合多优先级GPS调度模型,综合分析网络价格对网络性能以及对网络服务质量产生的影响,提出一种接近实际的网络QoS准入控制算法。仿真实验证明了算法的可行性。算法中价格的确定以适应各类流的丢包率指标和接入阻塞率指标为基础,得到了可以保证系统QoS性能并且可以提高系统的利用率的价格机制。
Besides technical factors, price also could make important effect of network quality of service (QoS). According to queue methods and economics theory, considering the certain relation between the price variables and the variables of the network users' requests in call admission, for a muhipriority GPS scheduler model, this paper analysed the impact of the network price on the network performances and the network QoS comprehensively and presented the network QoS call admission control algorithm closed to the real world. To prove it, gave a number example. Confirming of price in the algorithm considers the packet loss rate and the block rate in call admission of variety flow. It can ensure the system QoS performances and improve the utility of the system.
