  • The SwitchWare Project Active Network Research at Penn and Bellcore Active networks explore the idea of allowing routing elements to be extensively programmed by the packets passing through them. This allows computation previously possible only at endpoints to be carried out within the network itself, thus enabling optimizations and extensions of current protocols as well as the development of fundamentally new protocols. Welcome to the SwitchWare home page, describing the Active Networks research effort underway in the Penn Department of Computer and Information Science and Bellcore as well as pointers to related material.

  • However, current filters usually rely on the computer being attacked to check whether or not incoming information requests are legitimate or not. This consumes its resources and in the case of a massive DDoS can compound the problem.
  • The user's computer has to present a filter value for the server to do a quick check. The filter value is a one-time secret that needs to be presented with the pseudo ID. The pseudo ID is also one-time use. Attackers cannot forge either of these values correctly and so attack packets are filtered out.
  • Indeed, the IPACF takes just 6 nanoseconds to reject a non-legitimate information packet associated with the DoS attack.
