本课题设计了省层面部署和地市层面部署两套特征流提取方案,从可维护性、业务风险、所需资源、实施效果等方面评估选定推广方案,并已在China Net骨干网福建节点设备上正式部署,实现全省城域网HTTP请求报文流量汇聚在特定中继上,利用现有有限的DPI资源,实现对全网HTTP请求特征报文的全采集和DPI分析,预计可满足未来至少5年的业务发展,节省固网DPI流量分析系统扩容投资近千万。
This project designs two feature flow extraction schemes at province level and city level, and evaluates selected promotion schemes from the aspects of maintainability, business risk, required resources, implementation effect and so on. It has been implemented in China Net Backbone Fujian Node The device is deployed on the device to realize that the traffic of the HTTP request packets of the metropolitan area network converges on a specific relay. The existing limited DPI resources are used to realize the full collection and DPI analysis of the HTTP request feature packets of the entire network. At least 5 years of business development in the future, saving nearly 10 million investment in capacity expansion of fixed-line DPI traffic analysis system.
