Application research of P2P in manufacturing resource sharing

In the network manufacturing,there are a lot of manufacturing resource informations needed to be shared.Aimed at the limited capacity of service delivery and the network bandwidth bottlenecks of the realization platform and the inconvenient management of the shared resources,a sharing model of more to more is presented based on the traditional sharing model of centralized ASP and the P2P ideas.It stores the shared resources in the autonomous node,and the sharing is directly completed between the request and provider under the supervision of the P2P platform.Based on this model,a P2P platform construction is built.According to the platform,a P2P network topology and the query are described,and the shared resources are modeling using the object-oriented thought.And a two-way hierarchical trust mechanism is used to ensure the security of shared resources.The experimental results show the feasibility and validity of the method.
