防御分布式拒绝服务攻击是目前网络安全的一大难题,在应对分布式拒绝服务攻击的各种措施中,概率包标记技术是一种重要手段,受到了广泛的重视。文章对Savage提出的基本概率包标记以及目前的常见的概率包标记方案进行了分析研究,按照采用的标记手段和方法做了一定的归类并对其性能和效果进行了比较和分析,最后对概率包标记技术的发展趋势作了简单分析和展望。
Defense Distributed Denial of Service (DDoS) attack is a major challenge for network security. Among various measures to deal with DDoS attacks, Probabilistic Packet Marking (TBA) is an important method and has received extensive attention. The article analyzes the basic probabilistic package marking proposed by Savage and the common probabilistic package marking scheme. According to the marking methods and methods adopted, the article makes a certain classification and compares and analyzes the performance and the effect. Finally, Probability packet marking technology trends made a simple analysis and prospects.
