Enhancing survivability of internet appliances using an on-the-fly packet filtering method

Internet appliances have been used for various application-specific purposes. One of the challenges regarding the appliance is to enhance its survivability when confronted with more traffic than could be processed. In this paper, we propose a simple on-the-fly packet filter that can classify some good packets as well as some bad (attack) packets from the given packet stream, thus effectively reducing the workload that actually goes to the appliance.
