With the rapid development of Internet technology , is becoming increasingly popular form of streaming audio and video information , and the ever-growing user base . The streaming technology is widely used in multimedia news releases, online all aspects of the broadcast , video on demand , e-commerce , online advertising , telemedicine , distance education , Internet radio , real-time video conferencing and other Internet information services , attention to growing , especially streaming the quality of service is good or bad is under increasing attention of people . Streaming media technology has the characteristics of high timeliness of its direct impact on people's experience feelings , thus streaming media server once suffered a malicious attack , leading to the response delay even paralysis and the consequences will be more serious . This article as a starting point , the systematic study of traditional DoS, DDoS attacks , and in-depth analysis of streaming RTSP interaction protocol basis , the agreement specified launch DoS , DDoS attacks security loophole . Then designed and implemented a set of streaming DoS , DDoS attack defense program . The defense program effective denial of service attack detection and attack defense strategy based on self-similarity of network traffic . Finally, the experimental test , the results show that the effect of the sets of the defense program convection Media Services DoS , DDoS attacks defense .
