Performance Evaluation of FC Network in Airborne Based on ICP

As the central processing unit of avionics system,the performance of integrated core processor (ICP) network would affect the comprehensive performance of avionics system directly.In order to improve the software and hardware design of ICP,to enhance the overall performance of ICP system and to solve the communication efficiency problem of distributed computer system,an evaluation on the FC network performance in the ICP system of a certain aircraft is carred out.The test environment is set up under the premise of average transmission rate and average transmission delay.Two test approaches,including broadcast transmission test and loaded multi-pair concurrent test,are proposed based on single interface test method.By using the priority queue scheduling algorithm and the weighted round robin scheduling algorithm,the FC network performance under ICP working environment is simulated by experiments on the topology model,and the test result has been analyzed.The comprehensive evaluation method of Internet in ICP is proposed,which provides assistance for overall performance improvement of IMA avionics system.
