Problems solved by technology

However, with the increase in the size of the simulation system and the increase in the number of federation members, the data interaction relationship between federation members within the federation is complex, and the scale of interactive data increases exponentially, making network data transmission the bottleneck of the system operation, resulting in the operating efficiency of the simulation system. drop sharply

Abstract

The invention discloses an information transmission optimization method suitable for large-scale distributed joint simulation. The information transmission optimization method includes the following steps: S1: using a multi-federal configuration module to generate a gateway configuration initialization file required for gateway operation; S2: using communication The multicast address management module generates a multicast address mapping table; S3: Use the time statistics module to coordinate the time advancement of each federation. The outstanding feature of the information transmission optimization method is that it adopts a multi-federation architecture and highly scalable HLA gateway technology. By generating a multi-federation unified multicast address mapping table, the gateway no longer undertakes the function of information communication between multiple federations, reducing load. At the same time, through the establishment of a dedicated time system module, the function of multi-federation simulation time coordination is completed.

Description

technical field [0001] The invention relates to the technical field of information transmission in a distributed joint simulation system. More specifically, it relates to an information transmission optimization method suitable for large-scale distributed co-simulation. Background technique [0002] For the construction of a distributed simulation system, a distributed simulation architecture based on HLA (High Level Architecture, HLA) / RTI (RunTime Infrastructure, federation operation support environment) is usually adopted, and each simulation node in the simulation system is designed as an independent federation member , each federation member interacts with data within the same federation to promote the simulation run. However, with the increase in the size of the simulation system and the increase in the number of federation members, the data interaction relationship between the federation members within the federation is complex, and the scale of interactive data incre...
