Measurement and Evaluation Performance of Stream-Media Service Based on Active Measurement

Stream-media technology is a hotspot of research these days. The performance of stream-media service provided by the Internet based on TCP/IP protocol is always changing with the variation of network and is easily affected by the network parameters. During the developing of stream media, service performance Measurement is very important. This paper proposes parameter definitions to measure performance, from a user perspective, of stream-media, develops an appropriate measurement tool based on active measurement technology that focus on these agreed upon list of parameters, and builds a stream-media service performance test bed that allows us to systematically vary network characteristics. Then we analyze the service performance behavior under various streaming configuration and network conditions. While there has been research done in video measurement and characterization using custom tools, to the best of our knowledge, there have been no performance measurement studies where the researchers had control of the popular stream-media server, content parameters and network conditions between client and server.
