Embodiment Construction

[0030]The embodiment of the present invention provides a method of identifying a data stream, which can be implemented by a server that requires an application identifier corresponding to the data stream. The server can acquire data streams of each application, or can receive the data stream of the various applications collected at the gateway or other data stream acquisition. In order to prevent the payload field of parsing the message, the accuracy of the application ID corresponding to the identification data stream is low, and during the process of identifying the application ID corresponding to the data stream, the server can obtain the first N packets in the data stream. The message transmission attribute information is not parsed by the payload field of the message, and then generates a corresponding feature image according to the packet transfer attribute information of the continuous N packets, in turn, the feature image can be input to the pre-training image classification...

Abstract

The present application provides a data flow identification method and device, which belong to the technical field of the Internet. The method includes: obtaining the message transmission attribute information of N consecutive messages in the target data stream; generating the message transmission attribute information of the N consecutive messages according to the message transmission attribute information of the N consecutive messages The feature image; input the feature image into a pre-trained image classification model to obtain the target application identifier corresponding to the target data stream. Through the present application, the accuracy of identifying the application identification corresponding to the data flow can be improved.

Description

Technical field[0001]The present application relates to the field of Internet technology, and more particularly to a method and apparatus for data streams.Background technique[0002]With the development of Internet technology, more and more applications can transmit data through network, and the network is transferred in massive data flow. The server can provide different priorities to different applications, which make it easy to manage the data streams in the network, so the server needs to identify the application ID corresponding to the data stream.[0003]Different applications need to transmit content, so, when setting the feature library, multiple data streams of each application can be analyzed, and each application corresponding to each application can be extracted. The feature field is stored in the feature library with the correspondence of the application identity. When the server receives the data stream, the payload field of the packet in the data stream is matched by the...
