On the Security Effect of Abnormal Traffic Controller Deployed in Internet Access Point

ATC (Abnormal traffic controller) is presented as next generation security technology to securely support reliable Internet service in traffic-intended unknown attack. The key concept of the ATC is abnormal traffic monitoring and traffic control technology. When fault factors exist continuously and/or are repeated, abnormal traffic control guarantees service completeness as much as possible. The ATC with control policy on abnormal traffic is superior to the ATC with blocking policy as well as conventional network node, when the ratio of effective traffic to abnormal traffic is higher than 30%. As the proposed ATC can be applied to the edge point of backbone network as well as Internet access point, it guarantees network survivability and provides reliable Internet service.
