摘　　要：首先对业务进行分类,不同的业务对网络不同的要求使其具有不同的QoS参数约束。然后研究并提出了基于智能业务识别的QoS路由模型和路由结构,根据动态配置的安全/QoS策略,在业务识别的基础上,标志数据包,根据DiffServ代码点DSCP值选择合适的路由算法。并针对带宽-时延-时延抖动-丢包率限制路由提出了一种改进的启发式路由算法,将丢包率转化为可加性条件,并把带宽限制作为剪枝条件,最后通过实验证明了其可行性。At first, to classify the business in view of different requirements have different QoS parameters constraints. Then presents QoS routing model and structure based on traffic classification. The model consists of the components such as dynamic configuration of security/QoS policies, accurate traffic classification in real-time, packet marking, and choosing the fight muting algorithm according to the value of DSCP. And it presents an improved heuristic routing algorithm for the bandwidth-delay-delay jitter-packet_loss_rate limit routing. In this algorithm, packet loss rate can be converted into additive terms, and the bandwidth limit as pruning conditions. Finally, experiments prove the feasibility of the Qos routing model.
