采用云计算技术的网络流量检测

为了实现对现网大数据网络流量的实时、有效检测,提出了一种基于云计算的网络流量检测方案。该方案充分利用Hadoop平台Map/Reduce编程模型在海量数据处理方面的优势,采用分层化的设计思想,克服了传统检测方案在海量数据应用环境中效率低下、可扩展性与安全性不足的缺点。重庆移动DPI平台应用表明,该方案较为有效,流量检测效果良好,在大数据处理时效率较普通分布式处理有明显提高。

Network traffic detection with cloud computing

In order to detect the network traffic in real time and effectively, a traffic detection scheme based on cloud computing is proposed. The scheme makes full use of the advantages of Hadoop platform's Map/Reduce programming model and adopts the thought of hierarchical design to avoid the inefficiency, the defects of scalability and security of traditional detection schemes in big data application environment.The application of the proposed scheme in DPI platform of Chongqing Mobile Communication Company has proved its effictiveness. The detection result is satisfying and the data processing speed has been improved obviously compared with the common distributed processing.
