Design and Implementation of Performance Testing Utility for RTSP Streaming Media Server

RTSP has been widely used in a variety of streaming media applications and streaming service providers hope to choose a high-performance streaming media server to meet their needs, so it is an important research topic about how to evaluate the serving performance of RTSP streaming media server. This paper analyzes the performance metric of streaming media applications comprehensively, and proposes an approach to design and implement a Performance Testing Utility for RTSP Streaming Server. According to different stress test, the utility mainly evaluates a streaming server´s performance in the case of delivering a large number of concurrent streams and quantifies the statistics of various performance metrics. The tool utilizes multi-thread mechanism to create multiple pseudo-terminal instances to simulate a certain number of concurrent users for sending RTSP signals, receives media flow by a special IP address, analyzes RTP packets, and counts the related performance metrics value of the server. Experiments validate the efficiency and accuracy of the tool.
