摘要
随着虚拟专用网的发展,隧道交换技术成了近年来网络安全界研究的热点。但是,目前还没有形成一个统一的标准,且更多的局限于L2TP协议及静态交换。就此研究了VPN隧道交换技术,在此基础上提出了基于IPsec的VPN隧道动态交换机制,并设计了一种VPN隧道交换路由的动态查询算法,使得采用不同安全机制的安全域间“透明”的互联成了可能,实现了隧道的汇聚,能够有效的提高了虚拟网络的安全性、灵活性和可扩展性。
Although Tunnel-switching has become of focus of network secure area with rapid developing of virtual private network,there is not a standard and has more limited in static-switching.Based on research of current VPN tunnel switching technology,this thesis put forward a dynamic switching mechanism for VPN tunnel based on IPsec,and design a dynamical quering arithmetic for VPN tunnel-switching route.By enable secure-area that use different mechanism to transparent connect each other,and assemble different tunnel,this mechanism improve VPN＇S security, flexibility, extensibility.
