Existing VPN tunneling technology requires the introduction of expensive reliable dedicated line. As a result, homes and businesses that use common Internet have difficulty in operating a VPN. To  solve this problem, this paper proposes a VPN tunneling platform and implements the tunneling rate of at least 20Mbps. It also analyzes the amount of CPU usage and the packet drop ratio information used for the VPN tunnel for the real-time line prediction and line appearance without network load. Based on this, we implemented a technique for calculating a network speed in real-time by applying the queuing algorithm optimized for each network condition.
