A Study of Traffic Survivability Under Malicious Attacks

As the Internet becomes more mature and a part of our daily life, the management of its resources to provide guaranteed services is crucial and beyond the capability of every individual network domain. How to maintain its continuous services in critical conditions is a challenge and would affect the design of next generation network infrastructure. In this paper, we study the survivability of normal traffics under the influences of flooding-based denial of service attacks and propose a potential framework which would reduce such influences. Our research increases the understanding of the behaviors of flooding-based DoS attacks and provides potential trends for developing better malicious attack mitigating solutions. By taking advantages of the survivability of specific flows, the potential mechanisms will not change or only slightly change current network infrastructure and be able to perform quality of service for several existing applications with no or little investment.
