摘　　要：性能可扩展性是当前互联网面临的主要问题之一,对互联网开展有效的测量和评价,能为寻找提高网络性能的方法提供必要的数据支撑.目前,虽然在大规模分布式测量方面已经开展了大量的出色工作,但是它们无一例外地受到测量点数量和位置的限制.基于此,文中设计并实现了基于联邦架构的全球网络性能测量平台GPERF.该平台实现了大规模异构测量,充分利用了自有资源、伙伴资源和互联网上的开放服务等.文章将从体系结构设计、测量点发展、测量任务调度和应用研究等方面对GPERF展开介绍和讨论.The scalability of performance is one of the major problems of the current Internet. Accurate measurement and evaluation about the Internet can provide strong support for improving the network performance. To date, many large-scale distributed measurement projects have made great efforts to network performance measurement, but they are all bound to the number and location of measurement points. To solve this problem, the authors propose the global network performance measurement platform called GPERF based on a federation structure in this paper. GPERF is a large-scale heterogeneous measurement platform, whose measurement points include its own resources, partners＇ resources, and open services on the Internet. This article describes GPERF＇s architecture design, measurement point development, measurement task scheduling and applications.
