Abstract

The invention discloses a network flow classification method and device based on serialized protocol flow characteristics. The method comprises steps of dividing the acquired network packet into a plurality of network flows based on the packet header attribute characteristics of the network packet; calculating the similarity between the network packets of each network flow and clustering and labeling the network flows; performing serialization operation on the network flow with the label to obtain a serialized data set; inputting the serialized data set into a recurrent neural network, and extracting an association relationship between network packets; inputting the output sequence value of the recurrent neural network into a one-dimensional convolutional neural network to obtain a serialized feature vector set; and inputting the serialized feature vector set into an adaptive convolutional neural network to obtain predicted network traffic classification. According to the method, modeling is carried out by utilizing the data relationship between the time dimension and the space dimension of the network packet, so that the classification efficiency and the classification effect of the network traffic are improved.

Description

technical field [0001] The present invention relates to the technical field of computer communication, and more specifically, to a method and device for classifying network traffic based on serialized protocol flow characteristics. Background technique [0002] With the rapid development of the Internet, a large amount of data is generated in computer networks, communication equipment, network transmission, wireless communication and other scenarios. These massive data occupy a large amount of network bandwidth resources, cloud services and storage resources. If the data is not processed properly , It will lead to network paralysis, congestion or server downtime at any time. [0003] With the rapid expansion of the network scale, the data transmitted on the network from various network devices, mobile terminals, and servers has increased sharply. Such a large amount of data generated by network applications needs to ensure network data transmission in the process of transmis...
