Distributed Universal Number Discovery, or DUNDi, is a service discovery protocol that can be used for locating resources at remote locations. The original intention of DUNDi was to permit decentralized routing among many peers using a General Peering Agreement (GPA). The GPA (available at http://dundi.com/PEERING.pdf) is intended to take on the role of a centralized control authority with a document to create a trust relationship among the peers in the cloud. While the idea is interesting and sound, the GPA has not taken off. That doesn’t mean the DUNDi protocol itself hasn’t found a home though: the original intention of DUNDi has been expanded so that now it doesn’t just act as a location service, but can be used to request and pass information among peers.
