Applying of Websocket and WebRTC for Video Calling in Telemedicine during COVID-19 Pandemic

During the COVID-19 pandemic around the world, it is difficult to visit a doctor at the hospital. Many hospitals are trying to adapt to develop telemedicine systems to serve their patients. Hence the origin of this research as well is to develop a Telemedicine system to use Websocket and WebRTC have been applied to support video calling functionality in hopes of creating sessions to serve clients efficiently. This paper shows the results of the tests obtained when used in real-world applications on the internet which found that the results have been used network utility very efficiently. It averaged 1.86 Mbps for down link and averaged 1.66 Mbps for uplink bitrate, but still had high memory consumption. When compared to video calling active in the video conferencing system is still considered a waste of resources at 79% more than other systems.
