摘要
阐述应用基于4GVPDN的无线接入技术,设计适用于E化民机机载信息系统的地面支持网络解决方案。在飞机起飞准备/降落之后的场景中,利用L2TPoverIPSECVPN技术建立机载信息系统与地面支持网络的无线传输链路,并对网络连通性以及安全保障策略进行了研究,方案能够较好地满足机载信息系统与地面系统进行网络通信时对安全性、可靠性的要求。
This paper proposes ground support network design for E-enabled civil aircraft based on 4G VPDN technology. The proposed network can provide secure data transmission between the ground system and the aircraft during the take-off/landing period. The proposed network utilized L2TP over IPSEC VPN protocol, which can be installed in the onboard maintenance system of the current civil aircraft. Security analysis for network connection, IPSEC encryption, video transmission and data uploading/downloading demonstrates the feasibility of the proposed network design.
