Real-time Transport Protocol Introduction: RTP protocol Introduction, RTCP protocol Introduction, RTSP protocol Introduction (ZZ)

http://blog.csdn.net/heanyu/article/details/6202500 RTP (Real time Transport Protocol) RTP is a transport protocol for multimedia traffic on the Internet that is published by the IETF (Internet Engineering Task Force) as RFC1889 . RTP is defined as a one-to-many transmission, with the purpose of providing time information and implementing stream synchronization. Typical applications for RTP are built on U

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 transmissio

2.TCP/IP Protocol Analysis-IP Protocol, ARP protocol, and RARP protocol

The IP protocol is the most important protocol in the family of TCP/IP protocols, which provides unreliable, non-connected datagram transport services. So understanding IP protocols is critical to our learning network.IP headerImportant Field Introduction:4bit First ministerial degree: in 4 bytes, determines the IP head of the largest minister of 15*4=60, the general IP datagram header length of 20, at this

Summary of the SIP protocol stack design scheme

We also talked about the SIP Protocol and related SIP protocol stack. In this paper, we propose a software structure and design implementation scheme of the software telephone based on the SIP protocol. this solution is based on the embedded Windows CE platform. The middleware uses the Open-Source SIP protocol stack oS

Next-generation IP network transmission protocol-traffic control transmission protocol sctp

-->   核心提示:-->With the development of the IP network to the multi-service network, especially the development of VoIP in recent years, it is inevitable to transmit signaling messages in the IP network. But in the IP network cannot provide high-quality transmission services like mtp3 and ATM, so the ITU-T proposed an improved version of sscop-sscopmce in Multi-link and non-connection environment ), it is used to transmit signaling messages in an IP-bas

OMA Protocol WizardA concise tutorial to help you understand the OMA Protocol (i) (b) Unlike the TR069 protocol, because OMA is designed to support data synchronization between different devices across networks, OMA's data transfer is not only built on the Internet session layer using HTTP transmission, OMA also supports wireless network WAP using WSP and Blueto

Protocol Stack development for H.323 Protocol (1)

We have analyzed some protocols and the content of the protocol stack. I believe everyone understands the content of the H.323 protocol. Here we will explain the development of this protocol stack. Developing an H.323 protocol stack is an extremely arduous task in the communication design process. The difficulty lies i

TCP/IP Protocol, HTTP protocol, socket communication detailed

the internet, called an "IP address." With this unique address, it is ensured that users can choose their own objects from tens of thousands of computers efficiently and conveniently when they operate on a computer connected to the network. Now the telecommunications network is merging with IP network, IP-based new technology is a popular technology, such as IP network transmission of voice technology (ie, VoIP) is very popular, other such as IP Over

TCP/IP Study Notes (3)-IP protocol, ARP protocol, RARP Protocol

Transfer http://blog.csdn.net/goodboy1881/article/details/668556 ------------------------------------------------------ Put the three Protocols together for learning because these three protocols are on the same layer. ARP is used to find the MAC address of the Ethernet NIC of the target host, and the IP address carries the message to be sent. The data link layer can get the data transmission information from ARP, and get the data information to be transmitted from the IP address.1. IP
