摘要

为解决网络阻塞状态下用户QoS迅速降低的问题

提高网络系统对用户QoS的准确判定能力和动态调整能力

提出了一种保障用户QoS水平的动态自配置方法;采用效用函数对用户QoS优先级初始化表示

利用认知网络的主动特性和中断管理机制

通过认知节点对用户QoS优先级进行判定和动态修正。仿真实验和分析表明了所提出的方法优于传统的DiffServ

能够有效保障网络阻塞状态下用户的QoS水平。

Abstract

To solve the rapid drop of user QoS under network congestion

improve the accuracy of user QoS and advance the ability of dynamic adjustment

a dynamic self-configuration method for user QoS protection was proposed. Utility function was introduced to initialize the priorities of user QoS

and then the active features of cognitive network and the interruption management were utilized to determine the priorities and also correct them dynamically by cognitive nodes. Simulation results show that the proposed method is better than traditional DiffServ

and able to guarantee user QoS effectively in case of network congestion.
