摘　　要：结合分布式多媒体业务的应用需求,提出低消耗负载均衡的QoS路由技术,通过建立表征路径资源消耗的损益模型,将资源消耗的增量约束引入路径选择。研究了快速QoS重路由技术,引入重构代价计算模型,以此约束备选路由选择过程。理论分析表明该方法可有效提高路由恢复的时间效率,降低恢复延迟。建立了QoS需求变化动态感知的方法,通过自学习的样本训练原则建立统一的评价模型体系屏蔽参数间的差异性适应不同QoS能力参数的监测。理论分析表明该方法可有效提高检测的精确度,降低误检测率。In this paper, firstly, the low load balancing QoS routing technology is proposed with the application require-ments of distributed multimedia services in overlay network. Characterization of the path through the establishment on the profit and loss model of resource consumption, resource consumption will be bound into the path of incremental choices. Theoretical analysis shows that the method can effectively improve the efficiency of route recovery time and reduce the re-covery delay. Finally, a dynamic QoS-aware approach to changes in demand is established. The training samples by the principle of self-learning assessment model to establish a unified system of shielding parameters of the difference between the ability to adapt to different QoS parameters for monitoring.
