Bandwidth Management Analysis Using the Peer Connection Queue (PCQ) Method with Radius Authentication

This study examines the application of bandwidth control through the Per Connection Queue (PCQ) approach within the computer network of a vocational school in Bandung. The project aims to optimize bandwidth management for users, including students, instructors, and school personnel, utilizing Mikrotik routers and the Winbox program. The study confines its focus to the school's Wi-Fi network, which operates from 08:00 to 15:00. By limiting the study to specific aspects, the research aims to enhance its focus and yield accurate results. The research approach employs a descriptive analysis method to delineate the established bandwidth management system, in conjunction with the Network Development Life Cycle (NDLC) method for system development. Data collection is performed by configuring the PCQ, RADIUS authentication, and firewall and filtering parameters to block irrelevant websites. The system will undergo testing via simulation and installation to assess its effectiveness in improving network performance. The findings demonstrate that the PCQ technique effectively improves bandwidth utilisation, whereas RADIUS authentication provides an additional security layer for users within the vocational school network. The implementation of this system is anticipated to reduce internet disruptions, enhance service quality, and facilitate educational activities within the school. The research advocates for the establishment of a real-time monitoring system and the provision of training for network users to ensure efficiency and security.
