Abstract

Nowadays corporation networks are growing rapidly and they are needed to communicate with branch offices. Therefore, a VPN (Virtual Private Network) appears to reduce the cost of access and facilitate to manage and operate the enterprise network. Along with this trend, many studies have been done on VPN. It is important that the performance issues should be considered when VPN protocols are applied. However, most of them are limited on the tunneling methods and implementation of VPN and a few studies are performed on how installation of VPN affects the network. Therefore, in this paper, a testbed is constructed and VPN protocols are installed on it. Real traffic is generated and transmitted on the testbed to test how installing a VPN affects the network. As a result, layer 3 VPN protocol shows lower network performance than layer 2 VPN protocols. And we realize that the combination of L2TP and IPSec is the better method to install VPN than using IPSec only in the aspects of performance and security.
