摘要： 针对目前基于端口号匹配和特征码识别的流量分类方法准确率低、应用范围受限等问题，提出一种基于有监督的自组织映射(SSOM)的网络流量分类方法。该方法使用已标注类别的网络流量训练集，通过改变自组织映射(SOM)训练过程中的权值调整规则，使输出层中获胜神经元的选择更容易，各类别之间划分更清晰，从而提高分类性能。实验结果表明，SSOM的分辨率及拓扑连续性均优于SOM，对网络流量分类具有更高的准确率。

Abstract: In order to solve the problems in current work that relies on well known TCP or UDP port numbers or interpreting the contents of packet payloads, such as low accuracy and limited application region. This paper proposes a method based on a Supervised Self-Organizing Maps (SSOM) network classification method for traffic classification. The method uses training dataset of network traffic which has been labeled the traffic classes, and changes the adaptation rule of weighs in SOM training process, which easier to choose the winning neuron of output layer and divides each class more clearly, and improves the performance of classification. Experimental results show the SSOM network algorithm has a better resolution and a more continuous mapping than SOM. Its applying to network traffic classification has a higher accuracy rate.

Key words: Self-Organizing Maps(SOM), network traffic, classification
