Abstract

Methods and systems for providing directory services for peer-to-peer systems and applications are provided. Example embodiments provide a Peer-to-Peer Directory System ('PPDS'), which enables applications, especially those using peer-to-peer technology that desire to communicate directly with one another on different peer computer systems, to automatically discover working (current) network addresses for each other even when the network addresses of their respective computer systems change dynamically. The PPDS provides a community-based tracking system, a portion of which is implemented on each computer system that is a member of the community, to mutually track and store the network addresses of the other computer systems to which it has an associated relationship. The PPDS also provides a query mechanism that takes advantage of the relationship paths between the various computer systems to search for a current network address of a designated computer system.
