A static load balancing evaluation method for IMA system

Abstract

The integrated avionics system is a platform that integrates a series of flexible, reusable, interoperable hardware and software resources. It enables to implement the decoupled isolation of task software and physical resources under the premise of versatility of hardware resources and configuration of system applications, which can meet the requirements of software system updates and task changes with the possibility of dynamic reconfiguration in the event of a system failure. As the system hardware module is versatile, when the system task configuration and re-configuration, its partitioning and application configuration strategy determines the system comprehensive performance. On the basis of satisfying performance and reliability, the balanced distribution of task load can effectively improve the working efficiency of the system and reduce the possibility of failure. In this paper, we present a static load balancing evaluation method for IMA system based on the concept of distributed system load balancing. Aiming at the characteristics of strong real-time and two-level configuration of IMA system, we propose four evaluation indexes which are used to describe the load capacity of module and the communication ability between modules. And the application of the evaluation method in IMA system model analysis and reconstruction configuration is prospected.
