摘要: Since late 1999, DDoS (distributed denial of service) attack has drawn many attentions from both research and industry communities. Many potential solutions (e.g., ingress filtering, packet marking or tracing, aggregate-based congestion control rate limiting) have been proposed to handle this network bandwidth consumption attack. Among them, "ICMP traceback (iTrace)" is currently being considered as an standard by the IETF (Internet Engineering Task Force). While idea iTrace very clever, efficient, reasonably secure practical, it suffers a serious statistic problem such that chance for "useful" "valuable" messages can be extremely small against various types attacks. This implies most resources spent on generating utilizing will wasted. Therefore, we propose simple enhancement called "intention-driven" iTrace, which conceptually introduces extra bit in routing forwarding process. With new "intention-bit", shown that, through our simulation study, performance improves dramatically. work IETF's ICMP Trace-Back working group.
