Abstract

The invention discloses a high flux distributed type simulation support platform, a system and a simulation method based on the HLA, and is designed for large data amount simulation processing. The high flux distributed type simulation support platform based on the HLA includes that a runtime infrastructure (RTI) gateway and a RTI local process unit transmit data by calling a high flux data transmission control module. The high flux distributed type simulation support system comprises a reflective memory network and at least two simulation support platforms, wherein the reflection memory network comprises a multimode optical fiber and reflection memory cards connected with the simulation support platforms. The high flux distributed type simulation based on the HLA includes that internal interconnection and interoperation of federates are achieved through the reflection memory cards, and the reflection memory cards and the RTI gateway are connected by the reflection memory network to perform management and communication. The high flux distributed type simulation support platform, the system and the simulation method based on the HLA have the advantages of being applicable to simulation of big data high-speed transmission, low in delay, high in instantaneity, and rapid and reliable in data transmission.

Description
