Signaling Server - Everything You Need To Know

What's this blog post about?

A signaling server is a crucial component in establishing and managing communication sessions between devices on a network. It acts as an intermediary, facilitating the exchange of vital information such as media types supported, codecs, resolutions, encryption requirements, and network details like IP addresses and port numbers. The signaling server also assists in network traversal processes using Interactive Connectivity Establishment (ICE) framework to determine the best possible path for media transmission between clients. It maintains control over the session's lifecycle, ensuring secure communication by encrypting signaling data and handling authentication processes. Overall, a signaling server plays an essential role in enabling seamless, efficient, and secure communication setups.
