In this video, we demonstrate how latency can significantly impact the quality of video conferences, especially during activities that require real-time interaction like playing games. To illustrate this, my friend and I played the popular game "Rock Paper Seizures" while one of us intentionally used a network with high latency. As a result, you can see how even the slightest delay in data transfer can cause the video to lag, making it nearly impossible to play effectively.

The above figures display the results of our testing for various internet providers, showcasing the latency performance under both heavy and light network loads. By analyzing the data, we were able to observe how latency varies depending on the level of network usage.

A new device was added to set up to run SQM script and by using the Gigabyte Brix as a bridge, we were able to optimize network traffic between the Raspberry Pi devices, reducing latency and improving network performance. The addition of this device has significantly enhanced the capabilities of our network setup, enabling us to deliver a more reliable and responsive network connection.

In the following videos, we will observe how latency of each packet being transferred before and after implementing SQM. In the video there are two windows, the left one represents the command to run reverse traffic from the server to client, whereas the right window shows the time for each packet being sent to a server. Therefore when transferring reverse we will observe latency jump to high values (on the right window of the screen).
