Abstract

The present invention discloses an information transmission optimization method applicable to large-scale distributed joint simulation. The information transmission optimization method comprises the following steps: S1: generating a gateway configuration initialization file by using a multi-federation configuration module; S2: generating a multi-cast address mapping table by using a communication multi-cast address management module; and S3: coordinating time advances of federations by using a time-unified module. The outstanding characteristics of the information transmission optimization method are as follows: a multi-federation architecture and a highly extensible HLA gateway technology are adopted; and by generating a multi-federation unified multi-cast address mapping table, the gateway gets rid of the function of inter-federation information communication, and the load is reduced. Moreover, by establishing a special time-unified module, the function of multi-cast 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 (RunTimeInfrastructure, federation operation support environment) is usually adopted, and each simulation node in the simulation system is designed as an independent federation member. Members interact with each other within the same federation to promote simulation operation. 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 increases expon...
