IPv6 in IPv4 Virtual Private Network Based on Virtual Devices in Vehicle Information System

Article Preview

Abstract:

Vehicle information system is the data center of vehicle communication networks, for the sake of connecting the IPv6 host through IPv4 network area, a virtual network device (VND) in Linux embedded System is designed and implemented as a mid-layer module between the real device driver and internet protocol stack. The VND can establish a virtual tunnel between the vehicle information device and agent server. Both vehicle information device and agent server can support IPv4 and IPv6.Through the virtual tunnel, the agent server picked up the IPv6 packet which was built in IPv4 UDP data area, and transmit the IPv6 packets to the IPv6 remote server. So it works like a VPN device. The hardware platform of the vehicle gateway is based on ARM9, and the software is based on ARM-Linux. The instruction of hardware and software are as well as put forward.
