Signaling Protocols
Signaling protocols are communication protocols used to establish, control, and terminate real-time communication sessions, such as voice, video, or data sharing, over networks like the internet. They handle session setup, negotiation of media parameters, and connection management, but do not transmit the actual media data themselves. Common examples include SIP, WebRTC signaling, and H.323.
Developers should learn signaling protocols when building real-time communication applications like video conferencing, VoIP systems, or live streaming platforms, as they are essential for initiating and managing peer-to-peer or client-server connections. They are crucial in scenarios requiring low-latency media exchange, such as online gaming, telemedicine, or collaborative tools, to ensure proper session establishment and network traversal through firewalls and NATs.
