Abstract


In the rapidly developing digital era, the continuity of educational operations is highly dependent on the stability and security of computer networks. The main problem faced is internet connection disruptions that can hinder productivity. This study aims to optimize network usage in the  Lab of the Lhokseumawe State Polytechnic ICT Building. The methodology used is to implement Netwatch on MikroTik to monitor and redirect connection paths automatically when a connection failure occurs. Data collection was carried out through direct testing in the laboratory, and QoS analysis was carried out by measuring parameters such as throughput, packet loss, delay, and jitter before and after the implementation of the Failover method. The results showed that the implementation of the Failover method succeeded in increasing network management efficiency and significantly reducing downtime by 2 seconds when switching ISPs. Before the implementation of Failover, the average throughput was 1678.35 kbps, with 0% packet loss, 4 ms delay, and 16 ms jitter. After implementing Failover, the throughput increased to 1776.34 kbps, with 0% packet loss, 5 ms delay, and 6 ms jitter. The overall results of using the Failover method are effective in maintaining network availability and improving service quality in the  Lab.
