A new probabilistic packet marking technology based on path identification

In the article, we proposed a new probabilistic packet marking technology (called as P³M) based on path identification to defense serious distributed denial of service attacks and solve complex computation and other problem existed in traditional probabilistic packet marking (PPM) technologies. Our first contribution is constructing a new payload to carry router address and path identification. The second contribution is designing a new path identification scheme based on router addresses and hash algorithm. Our research indicates that comparing with based PPM, advanced PPM and other traditional PPM technologies, P³M has lower computation complexity and its response is faster. P³M is a practical technology to defense DDoS.
