CMAD-XCP:一种防御XCP协议公平性攻击的协同机制

CMAD-XCP:A cooperative scheme for defending against fairness attacks in XCP

针对XCP(eXplicit Congestion Protocol)协议分析公平性攻击的方法和特性,提出一种协同式路由器监控机制CMAD-XCP(XCP with Cooperative Malicious Attacker Detection)。CMAD-XCP由核心路由器感知恶意攻击,由边缘路由器实施对恶意流的区分和惩罚。仿真结果表明,CMAD-XCP可以及时、有效地惩罚恶意流,保护XCP协议的公平带宽分配,同时有效避免不公平竞争导致的网络拥塞。

An XCP-based Cooperative Malicious Attacker Detection scheme （CMAD-XCP） was presented. In CMAD-XCP, the core routers detect the malicious attacker, and the edge routers distinguish and punish the attacker. The simulation results show that CMAD-XCP can drop the malicious packets promptly, guarantee the fair bandwidth allocation and avoid the congestion due to the malicious competition.
