Session Description Protocol
Session Description Protocol (SDP) is a format for describing multimedia communication sessions, such as those used in VoIP, video conferencing, and WebRTC. It defines session metadata like media types, codecs, network addresses, and timing, enabling endpoints to negotiate and establish connections. SDP is typically used in conjunction with signaling protocols like SIP or WebRTC to set up real-time communication sessions.
Developers should learn SDP when working on real-time communication applications, such as video conferencing tools, VoIP systems, or WebRTC-based projects, as it is essential for session negotiation and media configuration. It is particularly useful in scenarios requiring interoperability between different devices or platforms, as SDP provides a standardized way to describe session parameters. Understanding SDP helps in debugging and optimizing multimedia streams in applications like live streaming or peer-to-peer communication.
