一、业务背景随着汽车保有量不断增加,基于车联网的各类智能车载应用进入了蓬勃发展阶段,车载智能应用的多元化为车联网的发展提供无限前景,而传统移动互联网组网扩展性差、安全性低等不足也对车联网的发展带来了挑战:1、组网扩展性差:目前车载拨号设备主要通过3G/4G上网卡直接接入公网,每辆车仅可获得单个动态拨号IP,车载终端的二、三层网络信息不能有效传递至位于云计算节点的智能车载应用平
I. Business Background With the increasing number of car ownership, various types of smart car-based applications based on car networking have entered a booming stage. The diversification of car smart applications provides an unlimited prospect for the development of car networking, while the traditional mobile Internet network has poor scalability , Low security and other challenges for the development of car networking: 1, poor network expansion: Currently, car dial-up devices directly access the public network through 3G / 4G network cards, each car can only get a single dynamic dial-up IP, car terminal two or three network information can not be effectively delivered to the cloud computing node intelligent automotive applications Ping
