Evaluasi Penggunaan Linux Router untuk Pembatasan Bandwidth Aplikasi Internet Tertentu

According to Cisco report in 2015, Internet usage has increased more than five times in the last 5 years, and it was projected to increase three times over the next 5 years. Increasing use of the internet is mostly caused by certain internet applications such as Flash, MPEG, video streaming, and P2P file sharing. Therefore, bandwidth configuration with traffic shaping method in Linux is needed in order to provide the needs of the Internet in accordance with user class. nDPI is used for classifying the data traffic in the Internet network. Work on the thesis focuses on the evaluation of the use of nDPI on bittorrent P2P applications. The evaluation was done using iptables to perform the data traffic marking and traffic control (tc) to do the bandwidth shaping. Bandwidth monitoring used iptraf applications on Linux and Networx application on the client. Based on testing performed, traffic shaping with nDPI coupled with cache successfully limited the bandwidth usage of  bittorrent P2P applications. The nDPI with cache was evaluated in different cache sizes and bandwidth limits. nDPI with size cache of 1024 entries is recommended. nDPI can not fully classifying bittorrent traffic correctly.
