Abstract: Peer to peer overlay networks o er a new way of communication. These networks do not need a central component like a server and scale well with the number of participants. Peerto- peer networks can connect millions of nodes e ciently while client-server solutions would need huge investments in server architecture. With a peer-to-peer overlay the costs of the infrastructure is fairly distributed among all peers. ChordNet aims to be a state-of-the-art peer-to-peer overlay that e ciently connects even large numbers of nodes. Another design principle for the ChordNet protocol is to be platformindependent and easy to implement. ChordNet is application neutral. That means that ChordNet simply delivers messages between nodes and manages the network. It does not de ne what kind of payload the messages contain. It is possible to have nodes running di erent applications inside the same network. ChordNet is based on ChordNet but seeks to x some of the shortcomings of Chord. It uses a 2-tier architecture with super-peer/edge-peer distinction that allows peers with rewalls/NAT1. ChordNet improves Chord routing e ciency and deals with special problems that arise when Chord is used as a general peer-to-peer network. Also ChordNet introduces a latency-based routing method for Chord networks. The long-term goal of ChordNet is to have a large-scale ChordNet overlay network in the Internet which is open for all nodes and applications which speak the ChordNet protocol. With this speci cation implementers should be able to create software that uses the Chord- Net protocol.
