Abstract:

A service framework in Military Information Grid (MIG) is proposed to integrate various battlefield information and the coordinated combat network is built. The framework can locate the required data in hundreds of geographically distributed sites. Vertically, it is composed of resources layer, grid-based service layer, metadata service layer, application service layer, and also user management layer. Meanwhile, the application service layer is horizontally partitioned into data service layer, information service layer, and knowledge service layer depending on to types of different service contents. The crucial functionality of metadata in the framework is demonstrated, and several related key techniques in the implementation are discussed. The framework is verified by the simulation in similar telecom scenarios based on service-oriented architecture. And it could be a feasible reference to meet the information sharing requirements of MIG.
