Analisis Manajemen Bandwidth Menggunakan Metode Proxy Server Berbasis Virtual Machine

Abstract

Bandwidth management is the process of measuring or controlling the network traffic communications and the data package on internet network to avoid network congestion and poor performance on the network. Internet access becomes slow due to the high of bandwidth traffic. This happens because internet users are increasing rapidly in the current era of developing technology, everyone uses the internet in every activity such as communication, learning and business. This problem arises in the environment of Medical Faculty, Islamic University of North Sumatra during the lecturing process because the students often access the streaming services during the lecturing process which makes bandwidth consumption bigger. The steps taken to overcome this problem are to build a cache proxy and bandwidth management with the Per Connection Queue (PCQ) algorithm and the use of virtual machines on a proxy server, one of which can save costs in building such an expensive server. The analysis was carried out using the Wireshark application based on Quality of Service (QoS) parameters towards the throughput, delay, jitter, packet loss and the efficiency as well as the time difference. Testing is done by accessing YouTube, Higher Education Report Forum and Facebook. Based on the analysis carried out, it showed that there is a decrease in the traffic and an increase in the efficiency reaching 58.02% when using a cache proxy. The results of testing and analysis using Wireshark are carried out by monitoring the density experienced when doing the searching so that it produces a value on the QoS Throughput Parameter of 1982 kbps, Packet loss 0.0% in the very good category, QOS Delay is 15.722949 with an average of 6.29 ms in the very good category and the total Jitter is 0.028658 with an average Jitter of 0.01145 ms in the good category.
