Performance Analysis of Rapid PVST+ Technology (Per VLAN Spanning Tree) On LAN Networks Using Redudancy Link Systems

This article discusses the application of Rapid
$\text{PVST}+$
technology in Local Area Network (LAN) networks to prevent network looping. The study used an experiment in GNS3 software to simulate a computer network. The objective was to analyze the performance of Rapid
$\text{PVST}+$
in forming a backup communication line, preventing network looping, and its impact on latency, throughout, packet loss, and jitter. The study found that Rapid
$\text{PVST}+$
can form a backup communication line in 3 to 5 seconds and prevent network looping. The latency value is affected by the number of switches that the backup communication line passes through. The more switches, the higher the latency value. The throughput value decreases with an increase in latency. Packet loss is affected by the size of the file used in data transfer testing. Jitter is influenced by the average latency or delay variation from the data transfer test results.
