基于网络断层扫描的网格网络性能测量分析

网格计算通过网络连接来获得一个高性能和高效的计算平台。网格网络的监测和性能测量为网格性能分析、负载平衡、任务调度等提供了重要的科学依据，而成为大规模网格服务的关键组件。现有的几种网格监测方法因缺乏对监测数据的推断分析而无法对网格网络的性能进行测量。通过对网格网络性能测量的特点、GloPerf及传统网络测量技术的分析，提出了基于网络断层扫描的网格网络性能测量方法。研究结果为网格网络性能的测量提供了新的途径。

Analysis of the Grid Network Performance Measurement Based on Network Tomography

Grid Computation is a distributed parallel computing system,acquired a high performance,high throughout and high efficiency computing platform by network connecting.As a large-scale grid service's important component,Grid network's monitoring and performance measurement play a major role for grid performance,load balance and task scheduling.While there are several approaches for grid monitoring,surprisingly,a very little research effort aimed at analyzing the monitored data for getting Grid Network performance measurement.On the basis of analysis of characteristic of the grid performance and the drawbacks of the GloPerf tool and the traditional network measurement technologies,this paper proposes a novel Grid Network performance measurement theory based on Network Tomography.The results of this paper present new theoretic foundations for measurement of grid network's performances.
