| 摘 要： | 网络路径的端到端性能直接决定了为用户提供服务的质量,网络路径性能的测量是网络运营和SLA(ServiceLevelAgreement)验证的重要组成部分。文章在描述端到端路径性能检测的一般性问题的基础上,提出了延时差平稳系数和绝对平稳系数作为测量检测网络路径性能的几个评价指标,作为已有的测量标准化工作的补充和利用网络测量进行端到端性能管理的参考方法。

| Abstract: | The end-to-end performance of the network path directly determines the quality of service offered to the user.Monitoring and measuring network path performance is a fundamental component of network operations and Service Level Agreement (SLA)verification.This paper presents the common problems of the end-to-end path performance de-tection.Based on delay measurement several evaluation metrics of path performance are also provided,which give the salutary complement to current standardizing work of Internet measurement and referenced approach to end-to-end per-formance management. |
