摘要
分组调度管理网络链路带宽,是实现网络服务质量的核心技术之一。介绍了一种先进的分组调度和资源管理模型———链路共享模型;说明了CBQ和H-WF2Q+两种不同的实现算法;分析了它们用于传输实时流的可行性。使用网络仿真工具NS2,对实时流传输的服务质量保证进行了仿真分析。仿真结果表明:该链路共享模型可以为不同的组织、不同的通信类型提供特定的服务质量保证,大大地提高了网络带宽的利用率。
Management of network link bandwidth using packet scheduling is one of core technologies for the guaranteed service quality of the network.When an advanced packet scheduling and resource managing model—link sharing model is presented,two different implementation algorithms including CBQ and H-WF^2Q+ are expounded.Then their feasibility for real-time streaming transmission is analysed.The use of a network simulating tool called NS2 analyses the simulation for the guaranteed service quality.The simulation result shows that this link sharing model can provide different organization and communications types with guaranted specific service quality,improving utilization of network bandwidth.
