Research And Implementation Of Distributed Air Traffic Management System Based On Dubbo

In recent years,the civil aviation industry in China has maintained a steady and fast developing trend,but the efficiency of air traffic management has yet to be further improve.The existing air traffic management system which based on IOE architecture already can't do better in the system availability,performance and expansibility.However,based on the distributed system structure,it can solve the above problems well.In this paper,through the analysis of the business characteristics of air traffic management system and the existing problems of single node system,modeling the business features of the system,extracted four types of business,eventually adopt the stratified and cluster distributed scheme for system improvement.First of all,research on the hierarchical structure of the system and what problems it can solve,and determine the hierarchical relations between layers,enhance the level of the logic system and the expansibility of the system.Next,research on the advantages of hierarchical structure clustering and the problem it can solve.Then,analysis and study the monitoring process of the cluster load information.This paper also presents the distributed design scheme of the aviation traffic management system.In this paper,the distributed air traffic management system is realized based on Dubbo framework,and the deployment and testing is carried out based on the virtual cluster of the local area network environment.The results show that the distributed scheme based on the hierarchical and clustering proposed in this paper can well solve the problems in the existing system,such as performance,availability,and expansibility,which also shows that the system has a certain application value.
