2022年5月27日 · RTP主要用于端到端传输音频、视频等实时数据，它不保证服务质量但通过RTCP进行监控。 文中详细解释了RTP的数据包结构、扩展头部以及RTCP的各种报文类型。

2015年6月16日 · RTP 由两个紧密链接部分组成： RTP ― 传送具有实时属性的数据；RTP 控制协议（RTCP） ― 监控服务质量并传送正在进行的会话参与者的相关信息。 实时传输控制协议（Real-time Transport Control Protocol或RTP Control Protocol或简写RTCP）是实时传输协议（RTP）的一个姐妹协议。 RTCP为RTP媒体流提供信道外（out-of-band）控制。 RTCP 本身并不传输数据，但和RTP一起协作将多媒体数据打包和发送。 RTCP定期在流多媒体会话参加者之 …

RTP基于UDP，其最主要的任务就是对语音数据 (包)进行实时传输。 通常一个VoIP通话会包含两个相对独立的单向RTP流。 QOS保障协议 VoIP中主要采用资源预留协议以及进行服务质量监控的实时传输控制协议来避免网络拥塞，保障通话质量。

RTP is used in conjunction with the RTP Control Protocol (RTCP). While RTP carries the media streams (e.g., audio and video), RTCP is used to monitor transmission statistics and quality of service (QoS) and aids synchronization of multiple streams.

It has been designed to provide an end-to-end quality of service which is important in voice and video transmission over IP networks such as the Internet or within corporate intranets. In this blog, we explore how RTP works in VOIP and some challenges faced by network managers?

Real-time Streaming Protocol is yet another signalling protocol like SIP but more suited in client-server applications while SIP is primarily designed for peer-to-peer calling. VoIP - It is an umbrella protocol that encompasses several different technologies to transmit Voice over Internet Protocol aka Voice over Internet/Network.

2004年12月30日 · RTP opens two ports for communication. One for the media stream (an even port number) and one for control (QoS feedback and media control) – RTCP. The port numbers are not hard defined, it depends very much upon the application. Actual voice packets are sent using RTP/RTCP for SIP VOIP calls.

Real Time Protocol (RTP) carries the voice payload across the network from transmitter to receiver. This payload is a continuous stream of packets that traverses the network. Most calls involve two streams: One for each endpoint.

2010年8月16日 · 本文介绍了RTP/RTCP协议在VoIP系统中的作用，RTP用于实时数据传输，RTCP则提供服务质量监控。 此外，还探讨了SRTP协议，它是为了解决VoIP安全问题而设计的，提供加密、认证和完整性保护。

RTCP is most commonly used in voice over IP (VoIP) and Internet Protocol Television (IPTV), streaming media and video conferencing. As the name suggests, the Real-time Transport Control Protocol is meant to control the transmission of data over a network.
