In this article, we will make a simple analysis of the three protocols and provide a multimedia application that has some practical value to achieve with these three protocols. 2 protocol analysis 2.1 introduction and

Let's talk about the "things" Of The osx sip mechanism"I. Preface OSX is an exclusive operating system developed by Apple for Mac products. It is the first FreeBSD-based system to adopt an object-oriented operating system. From the OSX V10.0-V10.8 version, OSX systems are all codenamed big cats, maybe old Joe is also a fan of cats (I am also a loyal fan of cats, haha ), the OSX system is evolved as follows: 2001Mac OSX 10.0 Cheeta Cheetah 2001Mac O

Session Initiation Protocol,sip is a signaling protocol that establishes, modifies, and terminates a session between two endpoints. SIP can be used to establish a multicast session for two-party calls, multiparty calls, or even Internet calls, multimedia calls, and multimedia distribution. The JSR 116:sip Servlet API is a server-side interface that describes cont

There are many tools used in Python in the swig (in English meaning: booze), sip (in English), and Boost.python. SIP is developed from Swig, and is specifically designed for Python to call C + + modules (see SIP naming to see, very interesting).SIP usage, in the official website of the

A technology, especially network-centric and communication-centric technology, has its own transmission protocol. Now we will introduce some knowledge about Cisco Unified Communication Protocols. So what is SIP when Cisco's unified communication protocol is used? Why is it used? Support for the SIP protocol in Cisco Unified CommunicationThe SIP Protocol provides

For multi-user communications, there are also common protocols for standardized management, such as the previously mentioned SDP and SIP (Session initiation Protocol), which is a control protocol belonging to the application layer, primarily used to create, modify, and abort sessions between one or more participants ( Sessions). The types of sessions include IP telephony, multimedia streaming, and multimedia conferencing.SIP IntroductionSIP invitation

Any package can be sent to the host's {A: B} address through the address {X: y}. Nat w

In the process of establishing a session, we must apply it to the SIP protocol. Some friends may not understand this agreement. It doesn't matter. Here we will explain the content of this Protocol. You may be familiar with the SIP protocol. The Session Initialization Protocol is an application layer control protocol. So what are more specific functions and applications? It can be used to create, modify, or

RTP/RTCP/RTSP/SIP/SDP relationship1. RTPReal-time Transport Protocol is a Transport layer protocol for multimedia traffic on the Internet. The RTP protocol details the standard packet format for transmitting audio and video over the Internet. RTP protocols are commonly used in streaming media systems (with the RTCP protocol), video conferencing and a Push-to-talk system (with either a/p or SIP), making it t
