In this paper, we proposed a P2P traffic management and optimization protocol named DDP (Domain Detecting Protocol). DDP works in a cooperative way between network providers and P2P venders. With a light-weight, flexible, and open framework, DDP can be attached to all existing P2P systems without changing the original P2P protocols. DDP can guide P2P traffic to match the topology of the underlying network as far as possible. We implemented DDP on BitTorrent protocol and deployed a DDP Caching system in a real MAN environment, and got excellent results in reducing BT traffic and optimizing user experience.
