摘要
在应对突发事件救援行动中,指挥中心能否通过互联网取得第一手资料,必要的条件是存在一个安全的连接。虚拟专用网(VPN)是应急现场组织、指挥的重要通信手段。但是,如果车载无线移动终端移动,由于IP的变化,安全连接将会消失,新的连接将会重新建立,造成应急现场与指挥中心之间通信不流畅。为克服以上不足,详细阐述了由L2TP和IPSec集成的一种新颖的隧道网络过程,并介绍了L2TP和IPSec的集成方案,最后完成了对本方案的测试。
To respond to emergencies rescue operations, command centers obtain first-hand information whether through the In- ternet. If a secure connectio, is necessary then a virtual private network （VPN） will be the emergency scene organization, the com- mand of an important means of communication. However, if the vehicle wireless mobile terminal move, secure connection will lost due to IP change and a new connection has to be reestablished, which result in communication between the emergency site and the command center is not smooth. To overcome the above shortcomings, the paper describes a novel network of tunnels by L2TP and IPSec integrated, introduces I2TP and IPSee integration solutions, and finally completed the testing of this program.
