为了减少不确定信息对QoS(服务质量)路由的选择产生的影响,因此有必要对具有不确定信息的QoS路由问题进行研究,讨论了网络状态的不确定信息产生的原因,并基于NS(网络仿真)软件,仿真分析了不确定信息对QoS路由和网络性能的影响,然后,结合QoS单播路由问题,通过对有关问题的形式化描述,讨论了相关的解决方案,最后,综合目前相关解决方案存在的优缺点,从实现的角度探讨了以延迟保证为约束条件的多路径QoS路由机制。
In order to reduce the impact of uncertain information on QoS (Quality of Service) routing, it is necessary to study the QoS routing problem with uncertain information, and to discuss the reason of the uncertain information of network status. Based on NS (Network Simulation) analyzes the impact of uncertain information on QoS routing and network performance. Then, combining with QoS unicast routing problem, the related solutions are discussed through formal description of the related problems. Finally, The advantages and disadvantages of the scheme are discussed and the multipath QoS routing mechanism with delay guarantee as the constraint condition is discussed from the perspective of implementation.
