深度包检测技术(即Deep Packet Inspection,以下简称DPI),是一种面向应用层分析的流量分析检测技术。DPI技术已成为高端网络设备的标准配置,用于对网络流量的精细化控制和分析,但是由于硬件性能、功能适配、系统架构等因素的制约,DPI一直无法在为数众多的低端网络设备(如家庭路由器、机顶盒、WIFI等)中广泛使用,从而导致面向广大终端用户和集团专线客户的高级流量优化和服务提升的缺失。为了解决上述问题本文提出了一种将深度包检测技术云化、通用化的方法,从而方便将其下沉用于更精细化的流量分析和控制。
Deep Packet Inspection (Deep Packet Inspection, hereinafter referred to as DPI), is a traffic analysis and detection technology for application layer analysis. DPI technology has become standard equipment for high-end network equipment used to fine-tune the control and analysis of network traffic, but due to hardware performance, function adaptation, system architecture and other factors, DPI has been unable to count on a large number of low-end network equipment (Such as home routers, set-top boxes, WIFI, etc.), resulting in a lack of advanced traffic optimization and service enhancements for a broad range of end users and group leased line customers. In order to solve the above problems, this paper presents a method to cloud and generalize the deep packet inspection technology, so as to facilitate its sinking for finer traffic analysis and control.
