Simulation results illustrate that this strategy can reduce the outage of the low priority traffic and make full use of the limited channel resource. 仿真结果表明,该方案可大大降低低优先级业务的掉线概率,充分利用有限的信道资源。
Numerical results showed that the service of both high priority traffic and low priority traffic was guaranteed by the new scheme, and moreover, the network utilization was promoted. 仿真结果表明,多优先级时延预留机制不但较好地提供了对高优先级业务的服务率,也保证了对低优先级业务的服务,同时网络利用率也相应得到了提高。
Furthermore, under the condition that the high priority service is ensured, the QoS of the low priority service is improved greatly when in heavy traffic. 当网络负载增加时,在保证高优先级业务服务质量前提下,大幅改善了低优先级业务服务质量。
So the authors propose the Enhanced Resource Shared Algorithm which adopts the new rules of resource sharing and does it best to use the low priority traffic resource as the backup resources of high priority traffic. 因此本章又提出了一种加强资源共享保护算法,该算法采用了新的路由策略,尽力寻找低优先级的业务资源作为高优先级的备份路资源。最后作者通过仿真分析了算法的性能。
