Computer Network Optimization Using Queue Tree and Peer Connection Queue (PCQ) Method at SMK Negeri 1 Sumbawa for Learning Support

Abstract

Bandwidth struggles and non-optimal internet networks can result in connection problems, such as slow connections and allowing users not to connect to the internet. therefore it is necessary to optimize computer networks to be able to maximize service to users, both used to find information, download and upload data. This study uses the Queue Tree and PCQ methods which aim to optimize computer networks at SMKN 1 Sumbawa Besar and improve the quality of computer networks in terms of delay, jitter, throughput, and packet loss. This type of research is qualitative and quantitative research. Research methods include data collection (observation, interviews, literature study), analysis, design, implementation, and testing. Based on the test results after using the Queue Tree and PCQ methods, the average values of delay, jitter, throughput, and packet loss are more optimal than before applying the Queue Tree and PCQ methods. The delay measurement in data rate before applying the Queue Tree and PCQ methods is 1414925 m/s and after applying the Queue Tree and PCQ average delay is 3,165 ms. Test Jitter on the data rate before applying Queue Tree and PCQ methods is 1414957 ms and after applying the queue tree and PCQ jitter is 3,164 ms, Throughput on data rates before applying the Queue Tree and PCQ methods is 5043 kbps and after applying the queue tree and PCQ throughput is 2486 kbps, Test packet loss on data rates before applying the Queue Tree and PCQ methods is 7,911% and after applying the queue tree and PCQ methods is 0,030%.
