传统的IP网络是针对数据业务设计的，只能提供数据传输的服务，并不具备调节网络资源使用的能力。为了将业务流合理分配到现有的网络拓扑结构，优化网络资源的使用，解决网络资源使用的不平衡，本文首先给出了一种区分业务流量工程的模型和目标，分析了单级链路流量调度，设计了多链路分级调度共享结构和流量调度策略。仿真结果表明，该方法能有效地改进区分服务网络上的多级流量拥塞控制性能，具有较快的响应速度、较好的稳定性和公平性，并且能适应网络的异构性。

Traditional IP network is designed for data business, but rather to provide data transmission services, it does not have the ability to regulate the use of network resources. In order to distribute the business flow in the existing network topology reasonably, to optimize the the use of network resources and resolve the problem of imbalance in the use of network resources, the model and target of traffic engineering based on differentiated services are presented firstly,and single level traffic scheduling is deduced,and the shared structure and traffic shaping policy of multilink and levelbased scheduling are designed.The simulation results show that this method can improve the performance of traffic congestion control, is more responsive, more stable and fair, and can adapt to network heterogeneity better.
