摘要
分布式拒绝服务(Distributed Denial of service,DDoS)攻击是网络安全的主要威胁之一。由于攻击源多采用虚假源IP地址,对攻击行为的溯源和应急处置工作面临很大困难。文章基于路由器的DDoS防御技术进行了分析,重点研究了边采样算法。通过ISP在传输网络路由器上设置DDoS防御系统是可行和有效的。
DDoS attack is one of main threat to network security. Looking for original address and taking appropriate action face great difficulties because of fake IP address used by hackers. This article analysis thechniques of DDoS defense based on routers, focuses on research of edge sampling algorithm. It is effective and reliable to build up DDos Defense System via ISP's backbone routers.
