// A network node with Real-time Transport Protocol (RTP) support.

// RTP provides end-to-end delivery services for data with real-time characteristics,
// such as interactive audio and video. It works alongside the RTP Control Protocol (RTCP)
// which monitors transmission statistics and quality of service.
