Distribution Of The Virtual Test System Operation Support System Structure

Distributed Virtual Test Architecture (DVTA) is combination of middleware spporting dirtribted virtual test's running. DVTA is the kernel of virual test and it renders services such as communication, data management and scheduling for virtual test. If DVTA want to spport construcation of virtual test system from component level to system level, and to have abilities to be integrated and extended, it must have a perfect architecture and an effective implementation.To achieve above object, this paper does research on DVTA in details. The work involves:1.This paper introduces the research's background and actualities in both here and abroad.2. Base on the analysis of HLA, TENA and VTB, this paper discusses their key points and relative merits.3. This paper studies three common RTI architectures and designs a layered distributed RTI architecture, a layered DVTA and a DVTA middleware. Some key points of DVTA middleware are described, such as mechanism of communication between object models, mechanism of compiling object model in advance, and mechanism of integration and communication between architectures.4. In this paper, a DDM based on the layer of interest is designed. This paper analysises expected performance of this mechanism.5. This paper designs a technical proposal of~* virtual test system. That technical proposal comprises five layers from top to bottom, including virtual test application layer, virtual test sever layer, virtual test data layer, virtual middleware layer and virtual test network layer.
