The Design And Realize Of The Middleware In Multi-user And Multi-task Synthetic Simulation Integrated Environment

Recently, simulation platform research has begun to focus on Synthetic Simulation Integrated Environment (SSIE). "Meta Synthesis"is the key point of SSIE which is synthetically integrated by all kinds of resource and provides synthetic solution. The operations of SSIE need multi aspects support of network environment, and middleware is the key technology of network interconnecting. Therefore it is important to research middleware of SSIE.This paper focus on the research of SSIE middleware and the main aspects are as follows:1,The basic framework of the SSIE is designed. On the basis of the analyses of the simulation integrated environment, basic framework of SSIE is designed,and each module's function is analyzed thoroughly. Then the complex problem of multi-user and multi-task environment is studied, and work-flow is used to describe and manage the simulation task. At last we compare simulation grid (SG), SSIE and cloud simulation platform which is meaningful for SSIE research.2,A management and attempter method is researched. At first we improve the "centralized-distributed" architecture. Referring to the SSIE's characteristic, we separate the resource management into digital resource management and set resource management. The digital resource adopts multi-layer model that achieves the resource's intelligent management. In allusion to set resource, the auto-detective mechanism is designed to construct the network and an error-containing mechanism for the attempter service node. At last model and task are formally described, and the attempter engine is designed.3,The SSIE middleware in the application system for designing remote sensing satellite is realized. Referring to the requirements of the application system for designing remote sensing satellite, the main concept of designing simulation system is generally introduced for remote sensing satellite, and then the attemptering service and computing service are design concretely. The appliance of this simulation system shows the SSIE middleware can satisfy the requirement of application system for designing remote sensing satellite and support the SSIE run smoothly.
