Real-time transmission protocol details

Real-time transmission protocol RTP 1. RTP protocol:RTP (Real-Time Transport Protocol) was originally used in 1970s to try to transfer audio files, divided into several parts to transmit voice, time signs and queue numbers. After a series of developments, the first version of RTP was released by a laboratory in the United States in August 1991. By the 1996 s of this century, a standard version was formed. Many famous companies such as Netscape claim t

Real-time transmission protocol Introduction: RTP protocol introduction, RTCP protocol introduction, RTSP Protocol Introduction

RTP (Real Time Transport Protocol) RTP is a transmission protocol for multimedia data streams over the Internet.Rfc1889Release. RTP is defined to work during one-to-one or one-to-many transmission. It aims to provide time information and implement stream synchronization. Typical RTP applications are built on UDP, but can also work on TCP, ATM, and other protocols. RTP itself only guarantees the

Efficient and real-time network conference data transmission library-UDT

In the development of video conferencing systems, we must ensure the reliability of audio and video data, because the video conferencing system is a very real-time system, if the network is not good, packet loss, data delay, and data congestion may occur, which may affect data reliability, this results in a reduction in the sound and video quality of the video conferencing system. So how can we implement real-time data, but ensure data reliability? In the previous article "video conferencing

H.264 Video Transmission System Based on RTP protocol

1.IntroductionWith the development of the information industry, people's requirements for information resources have gradually transitioned from text and images to audio and video, and are increasingly emphasizing the real-time and interactive access to resources. However, people are faced with another unavoidable embarrassment, that is, they have to spend a lot of time waiting for file transmission while seeing vivid and clear media presentations on

Basic router configuration and transmission protocol

In today's era of rapid network development, routers play an important role. Because the router acts as a relay system in the network layer,Provides a routing and forwarding function for data between the third-tier networks. Therefore, the functions, functions, and basic configurations of routers must be mastered as members of the IT industry.In the following, we will make a brief analysis on the vro from two aspects: how to set up the simplest network environment in the experiment, common situa

Data transmission in layer-7 networks

network history, the International Organization for Standardization (ISO) and the International Telegraph Telephone Advisory Committee (CCITT) jointly published a layer-7 Reference Model for Open System Interconnection. Network processes in a computer operating system include application requests (at the top of the protocol stack) to network media (bottom). The OSI reference model divides functions into seven discrete layers. Figure 2.1 shows the OSI layered model.    OSI Layer-7 Reference Mod
