Abstract

The invention discloses a memory planning method of a real-time network of distributed simulation. The method includes: S1, allocating spaces of all federates in a distributed simulation system in a shared memory space; S2, allocating spaces of elements of the federates in the spaces of the federates; and S3, carrying out reading/writing operations of the federates in a running process of the distributed simulation system according to running status of the federates. The method can increase a shared-memory utilization rate of the real-time network of distributed simulation.

Description

technical field [0001] The invention relates to the technical field of distributed simulation. More specifically, it relates to a memory planning method for distributed simulation real-time network. Background technique [0002] With the development of complex weapons and equipment becoming more complex and more competitive, in order to avoid risks, improve efficiency and reduce costs, when designing weapon systems, it is usually necessary to use computer modeling and simulation technology, communication technology and computer network technology. Conduct virtual simulation tests on equipment performance, technical indicators, and comprehensive effectiveness. The current virtual experiment mainly uses Ethernet as the platform and HLA / RTI as the basis. However, due to the uncertainty of the overhead of the TCP or UDP protocol transmitted by Ethernet, it is difficult for Ethernet to meet the high real-time requirements. Simulation System. In order to achieve the performance...
