public interface DHTService

extends net.jxta.service.Service

The interface defining the DHT Service The fundamental operations of the DHT are to define an indexing space and provide a mechanism to locate and route to an identifier. There are currently two types of DHT implemented: A ring-based algorithm (inspired by MIT's CHORD) A mesh-based algorithm (inspired by the Content-Addressable Network)
