Problems solved by technology

However, the current service does not support the prediction of the complexity of the simulation federation members, does not distinguish the priority of each federation member, and does not support the improvement of the overall operating performance of the simulation system
Therefore, as the simulation system and mathematical model become increasingly complex, occupying computer resources and communication traffic between models are increasing, the existing HLA service cannot solve the problem of load balancing of simulation resources and network traffic in simulation, and cannot The complexity of the model is linked to the balance of computing resources, resulting in inefficient operation of the simulation system

Embodiment Construction

[0031] Such as figure 1 As shown, the implementation system of HLA-oriented simulation resource agent service (SRAS, SimulationResource Agent Service) includes: Agent server, simulation service agent, simulation resource agent, member nodes and simulation resources; member nodes are federated members under the HLA specification , including simulation resources, such as simulation models, simulation processes, configuration files, log files, etc. Simulation resources generate simulation information during operation and use;

[0032] The simulation service agent provides the logical time and environment information of the simulation member nodes, and does not have mobility; the simulation service agent collects the operating environment information of the simulation node where it is located, communicates with other simulation nodes through the Agent communication language, and periodically publishes and receives other simulation nodes Operating environment information, obtainin...

Abstract

An HLA-oriented simulation resource agent service system, including Agent server, simulation service Agent, simulation resource Agent, member nodes and simulation resources; member nodes are federated members under the HLA specification, including simulation resources, and simulation resources are running and using The simulation information is generated during the process; the Agent server is responsible for providing the management environment of the entire life cycle of the Agent; the simulation service Agent provides the logical time and environment information of the simulation member nodes, and does not have mobility; the simulation resource Agent is a mobile Agent, which will simulate members, models Resources and state information are migrated; the dynamic migration strategy of simulation resources based on the HLA time advancement mechanism and the simulation environment is the rule for the dynamic migration of simulation resource Agents. Through the present invention, the dynamic migration of the simulation resources during operation is realized, and the optimization of the operation efficiency of the HLA distributed simulation system is realized.

Description

technical field [0001] The invention relates to a realization system of HLA-oriented simulation resource agent service, which belongs to the technical field of computer simulation. Background technique [0002] In order to meet the reusability and interactivity of the simulation system, the United States proposed the High Level Architecture (HLA) standard for distributed interactive simulation. As an international simulation standard, the HLA standard includes six categories of services including federation management and time management, and solves the problem of dynamic data interaction of distributed simulation models. However, the current service does not support the prediction of the complexity of the simulation federation members, does not distinguish the priority of each federation member, and does not support the improvement of the overall operating performance of the simulation system. Therefore, when the simulation system and mathematical model are becoming more ...
