【摘要】 以最小开销测量IP网络全网范围的带宽利用率和时延参数对于主动式和被动式的资源管理、灵活计费、以及智能规划,是一项关键性技术.提出一种针对IP网络带宽利用率和路径时延的有效测量模型.目标是确定覆盖全网的最小覆盖集有效的算法,使得网络测量的开销最小.开销最小化是一个组合优化问题,文中提出了改进算法,性能仿真结果显示改进后的算法对大范围的网络拓扑有效.更多还原

【Abstract】 Effective monitoring of network utilization and performance indicators is a key technology for many important networks management tasks in next generation IP networks. In this paper, we propose an efficiently monitoring bandwidth utilization and path latencies architecture. Our goal is to identify effective techniques for monitoring while minimizing the overhead. We also propose improved approximation algorithms for these optimization problems and our simulation results.更多还原
