基于IP坐标系统的QoS优化方法
|
摘要
分布式服务的网络环境是影响QoS的重要因素,由于实际网络中路由策略的影响,服务节点间延迟经常出现随机延迟污染和三角不等式违例等问题,从而导致节点坐标的计算产生误差.上述问题影响了服务响应时间和延时预测准确性,本文提出了一种基于分布式服务节点IP坐标系统的QoS评估与推荐策略,通过TO-Filter算法和Vivaldi算法,抑制污染和三角不等式违例从而提高服务质量,实验结果表明本文提出的方法在降低坐标抖动方面性能提升了8. 7%.
The network environment of distributed service is an important factor affecting QoS. Due to the influence of routing strategy in the actual network,the delay between service nodes often occurs with random delay pollution and triangular inequality violation,which causes the calculation of node coordinates. In this paper,a QoS evaluation and recommendation strategy based on distributed service node IP coordinate system is proposed. Through the TO-Filter algorithm and Vivaldi algorithm,Triangular inequality to improve the quality of service,the results in reducing the coordinates of jitter performance increased by 8. 7%.
