摘要
随着通信产业的发展,网络质量和稳定性显得愈发重要。DNS、SYN flood等网络攻击会占用现有的带宽,影响网络质量,而传统的防火墙又很难有效解决这类网络攻击,因此,对网络异常流量进行监测和溯源有着重要的意义。本文通过介绍网络异常流量监测和溯源分析系统的建设方案,阐述了系统的工作原理和实施方法,并结合当前现网数据对系统的实施效果进行了总结和展望。
With the development of communication, the quality and stability of network is more and more important. When DNS, SYN flood attacks network, it will occupy existing bandwidth, the impact of network quality, and traditional firewall is very difficult to effectively address such attacks, therefore, the network abnormal traffic monitoring and traceability of great significance. This paper describes the construction of abnormal network traffic analysis systems for program monitoring and traceability, described the working principle and implementation methods, combined with network data on the implementation of the existing network effect of the system are summarized and discussed.
