LTest - a tool for distributed network performance measurement

The growing amount of realtime applications in the Internet, like multimedia communication or online games, demands an appropriate assessment of end-to-end network performance. In this paper, we present LTest, a tool for distributed, middleware based network performance measurements. We also describe scenarios that help ISPs and content providers to monitor the service levels that will be perceived by users. Furthermore, a performance analysis and error estimation as well as sample measurements are presented within this paper.
