【摘要】 首先讨论了目前非常流行的远程视频等应用,分析了组播通信的过程.接着在对IPSec VPN体系进行剖析的基础上,指出了IPSec VPN系统对组播隧道支持较差的原因,从而提出了新的支持组播通信安全传输的Multicast over IPSec协议,并给出了协议实现的结构和流程.为了对协议模型进行验证,文章以FreeSWAN软件为基础,对Multicast over IPSec协议进行了设计和实现,并对实现后的原型系统进行了环境测试和数据分析.更多还原

【Abstract】 This paper first discusses the popular applications for example remote video,and the process of multicast communication. Based on the analysis of IPSec protocol architecture ,that IPSec can not support multicast well is got. So the new Multicast over IPSec protocol is exposed including its structure and procedure. The soft structure of FreeSWAN is improved to realize the protocol and the system test data are presented and analysed in order to validate this new protocol.更多还原
