摘      要：This paper presents DSI, a distributed service discovery and integration utility for service grid. The goal of DSI is efficiently to improve service publishing, deletion and lookup,decentralized control, scalability, and availability. DSI comprises a logically global metadata pool and a double-layered DHT (Distributed Hash Table). Efficient service publishing and lookup are achieved by adopting DHT. Clean service deletion is guaranteed by time-stamping. And system availability is improved by replication combined with automatic indexer selection. Experiments show that DSI can achieve short response time, low processing cost and high availability.
