WebRTCs<\/h3>\n\n\n\n<p>WebRTC<strong> <\/strong>is an open source protocol that supports exchange of text, voice, video, or any generic data between user devices in real-time. The foremost advantage of using Websockets is that it is an open standard that <strong>does not require a server<\/strong> to establish communication between peers. Consequently, it immensely reduces the latency when any form of communication takes place.&nbsp;<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>How does it work?<\/strong><\/h4>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"800\" height=\"418\" title=\"works-of-webrtc\" src=\"https:\/\/www.mirrorfly.com\/blog\/wp-content\/uploads\/2022\/12\/works-of-webrtc-800x418.webp\" alt=\"webrtc\" class=\"wp-image-24788\" srcset=\"https:\/\/www.mirrorfly.com\/blog\/wp-content\/uploads\/2022\/12\/works-of-webrtc-800x418.webp 800w, https:\/\/www.mirrorfly.com\/blog\/wp-content\/uploads\/2022\/12\/works-of-webrtc-350x183.webp 350w, https:\/\/www.mirrorfly.com\/blog\/wp-content\/uploads\/2022\/12\/works-of-webrtc-768x401.webp 768w, https:\/\/www.mirrorfly.com\/blog\/wp-content\/uploads\/2022\/12\/works-of-webrtc-150x78.webp 150w, https:\/\/www.mirrorfly.com\/blog\/wp-content\/uploads\/2022\/12\/works-of-webrtc.webp 1200w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><\/figure>\n\n\n\n<h5 class=\"wp-block-heading\"><strong>Step 1: Signaling&nbsp;<\/strong><\/h5>\n\n\n\n<p>This process sets up and controls the entire communication session.
