Research on hierarchical manufacturing resource sharing model based on the chord

In order to realize the sharing and full use of the distributed and stochastic manufacturing resources, a covering network structure of two-layer like Chord ring is constructed. According to the Chord protocol, a distributed manufacturing resource sharing system model is proposed, making logic subrings by the type of resources and the logic main rings by the super nodes. The relay of the resource rings and the convergence of different types of resources for application are completed by super nodes. On this basis a framework model of manufacturing resource sharing system is built. The sharing system prototype instance is given finally.
