Abstract:

In order to solve the problems existing in the application of current manufacturing grid, a resource discovery model of manufacturing grid based on the multi-region and multi-hierarchy tree overlay network for distribution deployment of application service provider （ASP） platform is proposed. Based on the proposed model, the mechanism of automatically constructing the model online is then dealt with, and the related information-updating algorithms with advancing wave style are presented. Moreover, the essence of the ASP application mode of the model is analyzed, and the mechanisms of resource discovery and the corresponding realization algorithms are investigated. As compared with the traditional typical models of resource discovery, the proposed model is more advantageous in terms of resource discovery and resource updating. A prototype system of enterprise information node is finally designed and implemented based on the proposed model, which can perform such functions as resource regis- tration based on eUDDI registration center, resource discovery, resource information monitoring and dynamic maintenance, and information exchange.
