Improving the network traffic classification using the Packet Vision approach
This work addresses the need for application-aware network management in future mobile architectures, offering a novel approach that enhances security and privacy, though it appears incremental as it builds on existing CNN technologies.
The paper tackled network traffic classification by developing Packet Vision, a method that converts raw packet data into images for use with convolutional neural networks, achieving outstanding performance on a dataset with four traffic classes.
The network traffic classification allows improving the management, and the network services offer taking into account the kind of application. The future network architectures, mainly mobile networks, foresee intelligent mechanisms in their architectural frameworks to deliver application-aware network requirements. The potential of convolutional neural networks capabilities, widely exploited in several contexts, can be used in network traffic classification. Thus, it is necessary to develop methods based on the content of packets transforming it into a suitable input for CNN technologies. Hence, we implemented and evaluated the Packet Vision, a method capable of building images from packets raw-data, considering both header and payload. Our approach excels those found in state-of-the-art by delivering security and privacy by transforming the raw-data packet into images. Therefore, we built a dataset with four traffic classes evaluating the performance of three CNNs architectures: AlexNet, ResNet-18, and SqueezeNet. Experiments showcase the Packet Vision combined with CNNs applicability and suitability as a promising approach to deliver outstanding performance in classifying network traffic.
