Abstract: Distributed Denial of Service(DDoS) attack is among the hardest network problems.To reply it,many kinds of schemes of countermeasures are proposed,these schemes all respectively have the good and bad points.But among these,an Adaptive Probabilistic Packet Making(APPM) is promising and using.In this paper,based on the snooped initial TTL value by the attacker,an adaptive marking scheme is improved,which is advantageous to resist spoofed TTL value,to reduce the router burden and save the IP packet’s space.

Key words: Distributed Denial of Service(DDoS), packet marking, Adaptive Probabilistic Packet Making(APPM), IP traceback

摘要: 分布式拒绝服务攻击是目前最难处理的网络难题之一,针对分布式拒绝服务攻击提出了多种应对方案,这些方案都各有优缺点,但其中自适应概率包标记受到了广泛地重视和运用。针对攻击者对TTL初始值的伪造提出了一种自适应策略,有利于防止TTL值的伪造,减少路由器处理器的负担,节省了IP包头的空间。
