Abstract:

VPN（Virtual Private Network）is a technique that uses encryption and communication protocols to construct secure data transmission channels in public  networks. Nowadays,it is the main choice to build secure VPNs using the SSL protocol. This paper analyses the internal working mechanism of turmel-base  d SSL VPN,and presents a new SSL VPN solution which is based on the distributed tunnel model according to its performance P2P technology,this solution uses the computing power of edge nodes to share the server＇s data transmission  ve the performance of point-to-point transmission, but also enhance the whole throughput of a VPN system.
