Abstract:

In this work, DDoS based on UDP was simulated in NS-2, Results show that traffic of network still has self-similarity when DDoS based on UDP is happening in the network regardless of different kind of attack model and different network load. This is significant to research of characteristic of DDoS traffic and defense against DDoS.

Key words:  self-similarity, DDoS, traffic model

摘要：

在NS -2中模拟了基于UDP协议的分布式拒绝服务攻击,实验结果表明,针对不同的攻击模型和不同的网络负荷,当网络中发生基于UDP协议的分布式拒绝服务攻击的时候,网络流量仍具有较好的自相似性。这个对DDoS攻击流量的特性和DDoS防御的研究都具有十分重要的意义。
