[0025] Unencrypted message identification function: P2P traffic identification technology based on application layer data detection uses protocol analysis and restoration technology to extract P2P application layer data (ie P2P payload), and judge whether it is by analyzing the protocol characteristic values contained in the P2P payload Belongs to P2P applications. Therefore, this type of method is also called Deep Packet Inspection (DPI). In the deep packet inspection technology, feature extraction is performed on the specific P2P protocol and its corresponding P2P system load to establish a feature library. For the real-time network stream flowing through, the pattern matching algorithm is used to determine whether it contains the feature string in the feature library. If the feature matching is successful, the network stream is P2P data. The message identification part of the present invention adopts the DPI scanning technology to identify the hash s...
