Streaming Media Data Packet Detection and Filtration Approach Based on Feature Analysis
Yang Rui-guang, Cai Yibing · 2012
According to security and stability requirements of real-time streaming media transmission,this paper proposes a feature analysis-based detection and filtration approach,which parses feature of message head and call signaling content by the analysis of streaming media transmission protocol and data's streaming features,and then establishes an intelligent model matching method on the basis of special rules set,to matchingly detect the data packets.Experimental results show that this approach gets comparative advantage in the false positive and false negative rate,and comparied with the 5-tuple data packets detection filtration approach,it provides more effective security filtration of streaming media data packets.
