Vehicle - based Heterogeneous Network Interconnection Model Based on Virtual Device

摘要

In order to solve the problem of the communication between the heterogeneous network and the various types of equipment and the Internet, a new, Vehicle heterogeneous network interconnection model based on Linux virtual device. In this model, the dynamic load characteristics of Linux modules and the virtual network equipment, To achieve the unification and interconnection between different types of devices Logically, A virtual network device layer is designed between the TCP/IP protocol stack and the device driver layer, All data in the system kernel and the real device communication through the virtual network device layer, The virtual network device provides a unified socket layer interface, The design and implementation of the upper application service is more simple. Experimental tests show, The model can be used to communicate between heterogeneous networks, Especially with Internet communication.
