摘要
Skype流识别的研究大多局限于在静态载荷特征和通信机制,没有考虑网络流特征在Skype流量识别中的作用.提出了一种基于朴素贝叶斯分类的Skype流量识别模型.选择流的连接特征和实时特征作为分类特征集,根据流的连接特征组织网络流,再进一步根据流的包长度、平均发送间隔和突发带宽消耗等实时流特征识别Skype流量.在北京联通骨干网络上的实验表明该模型能有效地识别Skype流,是一种有效的Skype流识别算法.
Most of the Skype traffic identification models are limited to Skype communication mechanisms and static payload characteristics. No net flow characteristics are considered in identification algorithms. To overcome this limitation, a hierarchical Skype traffic identification model based on naive Bayesian classification was developed. Flows were analyzed according to network connection modes. Results were then obtained according to real-time flow characteristics, such as packet size, average inter-packet gap and burstiness of bandwidth consumption. The validity of the algorithm was proven by testing conducted on the Beijing China Unicorn backbone network.
