Virtual Private Network System of Dynamic Tunnel End Type Manager Apparatus and Virtual Router for the same

摘要

The present invention relates to a virtual private network system with a dynamic tunnel end type and a virtual router and a manager apparatus therefor. A tunnel end table including several pieces of tunnel end information is provided to a terminal and a virtual router so that a single virtual router can use a plurality of tunnel ends. The tunnel end dynamically selected according to a predetermined rule to dynamically change a tunneling attribute. Therefore, since the tunneling attribute changes dynamically for each VPN communication, external hacking is difficult compared with a general VPN system, and so, the security of data transmission and reception can be improved.
