Abstract

Abstract: In previous study，to control the dynamic QoS routing，a new concept，QoS Fluctuation Function（QFF） has been proposed，furthermore，based on traditional distance vector routing protocol，a new Dynamic Distance Vector Routing（DDVR） protocol has been improved.To analyze the DDVR performance，widely simulation experiments are designed.Simulation results show that the DDVR not only supports to stabilize QoS level，balance networks load，but also improves scalability and robustness of routing protocol.

摘要： 在前期研究工作中，针对IP网络实时流的QoS需求，提出资源供需状态的新概念——质量水平涨落函数，并将传统的距离向量路由协议改造成基于供需平衡的动态距离向量路由协议。为验证改进协议的有效性，通过广泛的仿真实验深入分析动态QoS路由机制，实验证明基于供需平衡的动态服务质量路由不仅满足用户QoS需求，平衡网络负载，同时具有良好的可扩展性和鲁棒性。
