Embodiment Construction

[0030] An embodiment of the present invention provides a method for identifying a data stream, which can be implemented by a server that needs to identify an application identifier corresponding to a data stream. The server may collect data streams of various application programs, or may receive data streams of various application programs collected by gateways or other data stream collection places. In order to prevent the accuracy of identifying the application program ID corresponding to the data stream from being analyzed due to the payload field of the message, the server can obtain the first N messages in the data stream during the process of identifying the application program ID corresponding to the data stream The message transmission attribute information of the message does not analyze the payload field of the message, and then generates the corresponding feature image according to the message transmission attribute information of N consecutive messages, and then the...

Abstract

The invention provides a data flow identification method and device, and belongs to the technical field of the Internet. The method comprises the following steps: acquiring message transmission attribute information of N continuous messages in a target data stream; generating a feature image of the message transmission attribute information of the continuous N messages according to the message transmission attribute information of the continuous N messages; and inputting the feature image into a pre-trained image classification model to obtain a target application identifier corresponding to the target data flow. Through the application, the accuracy of identifying the application identifier corresponding to the data stream can be improved.

Description

technical field [0001] The present application relates to the technical field of the Internet, in particular to a data flow identification method and device. Background technique [0002] With the development of Internet technology, more and more applications can transmit data through the network, and massive data streams are transmitted in the network all the time. The server can provide different priorities for different applications to facilitate management of data flows in the network. Therefore, the server needs to identify the application identifiers corresponding to the data flows. [0003] Different applications need to transmit different content. Therefore, when setting the feature library, you can analyze and summarize the multiple data streams of each application, extract the feature fields corresponding to each application, and then you can use the The correspondence between feature fields and application IDs is stored in the feature library. When the server re...
