Abstract :
The more the times, the more Internet users. But the use of the Internet is considered
unsafe because information can be taken by irresponsible parties. VPN is a
communication security solution through public network such as internet. With the VPN
data passing through the public network will be encrypted so it is very difficult to retrieve
information by other parties. OpenVPN and SSTP are two VPN protocols that use SSL
security which has some advantages over other security such as IPSec to be considered in
choosing VPN technology. QoS (Quality of Service) of a network needs to be a
consideration in the selection of VPN technology because QoS is a benchmark of the
quality of a network in serving data. Parameters used are delay, jitter, throughput and
packet loss. This study aims to analyze QoS on VPN networks based on OpenVPN and
SSTP protocols using FTP (File Transfer Protocol) and video streaming services. In this
study found that delay and jitter in OpenVPN is smaller than SSTP on FTP service, while
in video streaming both are same. In addition, the throughput on OpenVPN is larger than
SSTP when using FTP services, while using video streaming are both worth the same.
The packet loss between SSTP and OpenVPN is the same in both FTP and video
streaming services..
