Research On Joint Dpi And Dfi Technology

Due to network technology now is growing so fast. In the face of change rapidly network technology and new types of network attack, or the rapid expansion of network scale. On network based detection and shunt technology hat put forward higher requirement and challenge. The traditional network security checks are often only for the transport layer the following data, the traditional detection algorithm is also often with network load and storage capacity and other related. Be unable to meet the rapid expansion of the network scale and the rapid growth of internet users.In my paper, it is based on stereo matching algorithm for deep packet inspection(Deep Packet Inspection, DPI) research, it is performed for the data packet content filtering model packet detection technology. Its processing speed is very fast, satisfy the processing speed and low memory requirement. In addition, in order to ensure the accuracy of detection of DPI technology, and then based on machine learning models and classification rule and assessment of the depth of data flow testing technology (Deep Flow Inspection, DFI) technology research. On this basis, the effective integration of DPI and DFI technology, put forward to effectively identify the network the main flow of type P2P method.
