Embodiment Construction
[0020] figure 1 The flow chart of the method for classifying Internet data streams provided by Embodiment 1 of the present invention, such as figure 1 As shown, the method may include:
[0021] Step 101, extract feature data of the data stream to be classified according to classification requirements.
[0022] Specifically, feature data may include, but is not limited to: flow table relationship features between packets and other packets, statistical features of packets (such as packet length, time interval, etc.), topology characteristics of packets in the network (such as : connection relationship between hosts, etc.), message load characteristics (such as: ASCII distribution, encryption, etc.), etc. Classification requirements can be understood as the purpose of Internet data flow classification. For example, the purpose of Internet data flow classification is to distinguish the data flow in the network into long packet flow and short packet flow, so the dimension feature...
