基于ASP的制造网格资源发现模型

Resource Discovery Model of Manufacturing Grid Based on ASP Mode

针对制造网格应用上的困难,基于应用服务提供商(ASP)模式,提出了基于多区域多层次树型覆盖网络的ASP平台分布的制造网格资源发现模型,在此基础上提出了自动在线组建机制及其波浪推进式的信息更新算法,剖析了模型的ASP应用模式的本质,进而给出了资源发现机制及其实现算法.与传统的典型资源发现相关模型相比,该模型在资源发现和资源更新方面更具优越性.文中还基于该资源发现模型,设计并实现了包括基于eUDD I注册中心的资源注册、资源发现、资源信息监控与动态维护以及信息交流等功能的企业信息节点原型系统.

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.
