In this research, we propose an architectural solution to implement the Virtual Private Network (VPN) technology in campus environment between branches. The objective of this evaluation is to measure the quality of the streaming on client server performance over VPN technology. Virtual Private Network (VPN) technology has become a discussion issue for this time being. Today, the deployment of this technology on an organization truly can give a great privacy and security benefit over campus branches. Therefore, this study is to analyze the VPN over open source application and hardware device performance areas evolved with the quality of service delivered by streaming activities between branches. This study focuses on quality of voice prediction such as ⅰ) the performance of streaming activity (traffic in and out) and ⅱ) delay based on round trip time (RTT). In this study, network management system (NMS) is used to monitor and capture the performance of VPN in campus environment In addition, the most apparent of implementing VPN in campus environment is to define the best solution between open source application and hardware device that can be used in operational environment. Based on the finding result, the VPN measurement through hardware device is able to contribute better performance compare to open source application.
