The Effect Of Queue Tree On Packet Loss In Bandwitch Management Online Based School Exam

Abstract

Unequal bandwidth distribution between clients that are used for online tests will cause the quality connection among clients to differ. Especially when some client dominates the bandwidth. The other client will suffer to have a proper connection. Using Queue Tree bandwidth management with the type of Per Connection Queue (PCQ) the distribution of bandwidth can be done evenly among clients. The implementation of PCQ Queue Tree is able to reduce the length of ping time by 90% from 134 ms and 13 ms. Delay is decreased 47% from 17 ms to 9 ms with a very good category. Jitter decreased 41% from 17 ms to 7 ms with a very good category. Throughput increased 53% from 234.582 Kbps to 503.584 Kbps in the medium category. Meanwhile, in the packet loss parameter, there is no difference in conditions before and after the implementation of PCQ Queue Tree because there is no packet loss during the test, which means packet loss condition is in the very good category.
