AMS Based Step-tracking Scheme for DDoS Attack Sources

摘要

In this paper a new scheme is presented. This scheme is based on Advanced Marking Scheme (AMS), and it works with Autonomous System (AS). In autonomous systems, routers are divided into two categories-border routers and internal routers. It can reduce the number of routers involved in marking and the number of marked packets, further improves the efficiency and reliability of the reconstruction of the path by different types of routers using different markers. Simulation results from the experiments show that obtained results are the same as theoretical results. Performance analysis and simulation experiment results shows, compared with then conventional methods, the new algorithm improves the performance of IP trace back technique obviously.
