摘要
目前,电信骨干网络大量采用2.5Gbps和10Gbps链路,对这类链路的流量进行审计必然需要采取机群方式,因此,如何进行负载平衡,如何尽可能减少后端分析系统的负载是迫切需要解决的问题。本文提出了一种基于两级审计的网络信息审计系统T-DNIAS,它由三部分组成预处理分流结点、审计结点和控制结点。实际应用表明,它能有效地对内容进行审计,识别非法信息,并且所需要的审计结点非常少。
The backbone links are now upgrading from 2. 5G bps to 10G bps, how to solve the load-balancing problem and reduce the loads of back-end analysis systems are imminent. This acticle introduces a network information auditing sys tem based on two-level audit(T-DNIAS) ,which consists of a preauditing node, an auditing node and a control node. The system recognizes illegal information efficiently,and needs few auditing nodes.
