Bandwidth Utilization Analysis for TVET Education on Metro-E Campus Network

This paper presents a bandwidth utilization analysis and internet application usage for Technical and Vocational Education and Training (TVET) education on the Metro-E campus network. Despite upgrading high-speed Internet from 50Mbps to 150Mbps, the campus is still experiencing internet link congestion, affecting the Quality of Services (QoS). Campus QoS was analyzed, and data was collected over three months on a campus Metro-E network at the primary Internet gateway. The results show the bandwidth consumption for the Integrated Performance Modeling Environment (IPME). Inbound network capacity usage peaks at 100<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">%</sup> and then drops to 30% of available capacity, demonstrating that the network experiences both high and low demand times. However, Unifi broadband shows that inbound data usage ranges from 72% to 100%. The high demand for inbound Unifi traffic could suggest a critical service or a strong reliance on Unifi for inbound communication. PERDA-TECH students use most of the total 22014300.81MB of inbound data from online applications. They use these internet apps for E-learning and online simulation, YouTube, TikTok, and Facebook for multimedia and creative learning, and FTP applications for transferring files across websites or enhancing information. This research is significant in deploying QoS bandwidth management, policing, and shaping future QoS for TVET education on the Metro-E campus network.
