Abstract

The demand for video streaming services is constantly increasing, which requires reliable network performance with high Quality of Service (QoS). One of the solutions to improve network performance and guarantee QoS is to implement Multiprotocol Label Switching (MPLS). This research aims to analyze and compare the performance of non-MPLS and MPLS virtual IP networks on video streaming traffic. The research method is conducted through experiments by implementing two routing scenarios, namely non-MPLS networks that implement the Open Shortest Path First (OSPF) protocol and MPLS networks that implement OSPF with the addition of MPLS mechanisms. Tests were conducted using iPerf3 to measure UDP and TCP traffic (upload and download). In addition, QoS parameter analysis was conducted using Wireshark software on video streaming services with 360p, 480p, and 720p resolutions. The results show that MPLS networks can increase throughput, reduce delay and jitter, and reduce packet loss, especially at higher video resolutions. Video with 720p resolution experienced the most significant improvement, namely the throughput value increased by 40.73%, while delay and jitter decreased by 29.40% and 30.28%, and no packet loss was found. This shows that MPLS performance can provide better data transmission for real-time multimedia services such as video streaming.

Abstract

The Very Small Aperture Terminal (VSAT) antenna is a crucial component in satellite communication that requires accurate orientation to maintain signal quality. Orientation changes due to impacts, vibrations, or weather conditions can degrade signal performance. This study designs a real-time antenna angle monitoring system based on the Internet of Things (IoT) using an Inertial Measurement Unit (IMU) sensor, the MPU-9250. The system consists of a transmitter node and a receiver node. The transmitter node detects the antenna's elevation and azimuth angles using the MPU-9250 and sends the data via the LoRa SX1276 915 MHz module to the receiver node. The receiver node, equipped with an ESP32, sends the data to the Firebase Realtime Database and automatically delivers notifications via a Telegram bot when a directional change is detected. Testing results show that the MPU-9250 accurately detects angle changes, indicated by increased Signal Quality Factor (SQF) values when the antenna is in its optimal position. LoRa communication remains stable up to 20 meters, with a significant signal quality drop beyond 25 meters. The system effectively monitors and alerts directional changes of the antenna in real time, helping to maintain optimal satellite communication connectivity.
