Performance Test and Analysis of Ground-Air Communication Network based on IPSec VPN

Due to the advantages of authentication, integrity, confidentiality, encryption and non-repudiation, IPSec VPN has been widely used in the field of remote access and civil aircraft ground-air communication. IPSec VPN provides strong support for the safe transmission and exchange of ground-air data of civil aircraft. Its performance has a great impact on the data transmission of airborne information system. Therefore, it is necessary to test the performance of the ground-air communication network based on IPSec VPN. This paper first introduces the architecture of IPSec and the process of message processing. Then according to the actual application requirements, the test content of ground-air communication network based on IPSec VPN is determined, and the performance test platform of ground-air communication network based on IPSec VPN is built. Finally, the performance of different scenarios and configurations of IPSec VPN network is tested and analyzed, and the test results are given.
