一种新型的应急卫星通信VPN技术研究
Research on a New Emergency Satellite Communication VPN Technology
摘要
Abstract
It is very important to use the satellite communication system to communicate in the process of dealing with public safety emergen-cies and natural disasters.An excellent satellite communication system can complete the communication task safely,quickly and economical-ly.At the same time,it can join forces,command center,decision support system and the existing mobile,fixed communication network to constitute a unified emergency linkage command system.Traditional VPN technology is generally applied to the enterprise network in the In-ternet and other networks on the extension,to provide high-performance,low-cost network access,with its improvement and optimization on the basis.Through the China Telecom Satellite Communications Corporation to rent a data line,each terminal accesses into the Internet through the large S satellite,and the emergency platform and emergency command center form a complete emergency system through the VPN gateway.The use of UDP protocol and satellite for data transmission,and IPSec protocol to protect data security,a logical communica-tion network is constituted on a large S satellite communication network,which makes the satellite communication terminals from the groups or departments or users composed of self-management of the communications network.Due to the unique advantages of the satellite commu-nication network,such a communication network will have unprecedented emergency communication robustness.关键词
