A Buffer Coordination Method Based on Message Priority

Abstract

The invention belongs to the field of distributed system simulation, in particular to a buffer area coordination method based on message priority. The buffer area coordination method based on the message priority includes displaying jam problems through analyzing situations appearing in the simulation running process; analyzing the type of federate member event message and action on the simulation process, and dividing priority for the event message; adding a message buffer area to the situation display federate member, and dividing the buffer area according to the message type, wherein the buffer area is located between a scene display unit program and a federate member message data receiving program; setting an alarm value for each type of message data buffer area, when the buffer area occupancy volume reaches or surpasses the alarm value, processing the message data according to situation; processing the data and optimizing the buffer area occupancy volume to enable the situation display effect to be smooth. The buffer area coordination method based on the message priority dynamically regulates the buffer area so as to improve the situation display effect smoothness based on guaranteeing the simulation process logic correctness.

Description

technical field [0001] The invention belongs to the field of distributed system simulation, in particular to a buffer coordination method based on message priority. Background technique [0002] With the continuous expansion of simulation application fields, distributed simulation technology has gradually become the mainstream technology widely used. High-level architecture HLA (High Level Architecture), as a standard architecture in the field of distributed simulation, improves the interoperability and scalability of the simulation system, and supports the interaction of various federation members. HLA provides a universally applicable simulation function framework, and gives corresponding definitions to the functions of the components of the simulation system and the relationship among them. Under this framework, various simulation processes work together to achieve interoperability. HLA separates the underlying data communication platform from the upper-level simulation...

Problems solved by technology

However, during the actual operation of the simulation system, there is a problem that the status display on the STK end is not smooth

Analysis of the reason is that the rate at which the HLA end receives data is much greater than the rate at which the STK end extracts data, resulting in unbalanced data processing, resulting in delays or even pauses in STK display
