Explanation
RTP (Real-time Transport Protocol) is the standard protocol used to carry voice and video over IP networks, but it is predominantly associated with VoIP phone communications. Prioritizing RTP via QoS ensures voice packets are delivered with low latency, low jitter, and minimal packet loss-the three factors most critical to call quality. Because voice is highly sensitive to even small delays (>150ms degrades call quality noticeably), QoS prioritization is essential. Web downloads, streaming video, and BitTorrent are more tolerant of variable latency and do not rely on RTP in the same mission-critical way that VoIP phone systems do.
