Abstract: This paper investigates the method of implementing a virtual network system among containers. We first implement a testbed environment for Virtual Private Network (VPN) systems in IPv4 (site-to-site, host-to-host) and IPv6 (site-to-site). Then, we compare VirtualBox-based Vagrant with Docker Compose in realizing the same networking features. The result shows that migrating the virtual Machines (VM) to the docker containers can save nearly 90% of CPU time and 94% of memory for the VPN system. At the same time, the host machine still has no security risk increase.
