25%. Solution to improve network performance is to design bandwidth management using the Per Connection Queue (PCQ) method. The method is designed for network condition that have many clients where the distribution of bandwidth can be done evenly because PCQ has complexity in determining parameters by grouping based on source and destination traffic. Traffic prioritized by schools regarding the use of Zoom Application as an online learning class. To fulfill this purpose, the determination of the pcq-classifier based on the zoom ip address is chosen, so the zoom traffic is a network priority. After the configuration done, the QOS calculation is carried out again to prove that the network has undergone significant changes. The results show that the throughput has increased by 84.99%, result of delay 146.87 ms and packeloss 0%, so based on the TIPHON standard it is included in the "good" category. This is proof of success in managing bandwidth on the network. Keywords: Mikrotik RouterOS, Quality of Service, PCQ, TIPHON Standart" />
