Abstract: Aiming at solving problems existing in centralized and traditional distributed service discovery mechanism,a new service organization model was proposed.It identifies service by semantic string that comes from a semantic tree based on services functions in the service system.With an improved algorithm based on Kademlia,the model organizes all the services to form a P2P overlay network in which nodes are gathered together according to the semantic tree and can be found using semantic strings.This model has solved the single point failure and bottleneck problem,can find and invoke service without service registry.It is highly scalable,and supports more high-level applications such as dynamic scheduling,fuzzy search.The approach has been successfully applied in a service computing platform,which has already been verified and well operating nearly a year.

Key words: Peer to peer,Service discovery,Semantic tree,Fuzzy search
