采用分布式监测机制来实现多媒体网络业务QoS(服务质量)保证是一个重要的研究方向。首先分析当前多媒体网络QoS分布式监测方法的相关研究;然后将移动代理技术引入QoS分布式监测方法,提出一种基于移动代理的QoS分布式关联监测框架;并以该框架为基础提出一种基于移动代理的QoS劣化网段定位方法。仿真表明了该方法的实时性和有效性,也表明提高了网络接口利用率和减少了网络时延。
It is an important research direction to adopt the distributed monitoring mechanism to guarantee the quality of service of multimedia network. First of all, it analyzes the related research of current distributed multimedia network QoS monitoring methods. Then, it introduces the mobile proxy technology into the distributed QoS monitoring method and proposes a QoS-based distributed association monitoring framework based on mobile agent. Based on this framework, QoS Degradation Segment Location Method of Mobile Agent. Simulation shows the real-time and effectiveness of the method, also shows that the network interface utilization and reduce the network delay.
