What is the SIP protocol?

In many popular network technologies, we can see the content of the SIP protocol. So many people will doubt what the SIP protocol is? Let's take a look at it. SIPSession Initiation Protocol) is an application layer control Protocol defined by IETF Based on IP. because SIP is a plain text-based signaling protocol, it can manage meetings on different access networks. A meeting can be any type of communication between terminal devices, such as video meetings, instant information processing, or collaborative meetings. this Protocol does not define or limit services that can be used. Transmission, service quality, billing, security, and other issues are all handled by the basic core network and other protocols. SIP has received strong support from Microsoft, AOL, and other vendors, IETF, 3GPP, and other standards-making institutions. A network supporting SIP will provide a bridge to expand and provide integrated service capabilities to various devices in the Internet and wireless networks. this will allow operators to provide a large number of information processing services for their mobile users, and interact with fixed users and 2G wireless users through SMS. SIP is also a signaling protocol used in UMTS3GPP R5/R6, so it can protect the operator's current investment and have technical advantages and commercial value.

After learning about what the SIP protocol is, let's take a look at the features of this technology.

Technical advantages of SIP:

* Independent from access: SIP can be used to establish meetings with any type of access network and enable operators to use other protocols.

* Meeting and Business independence: SIP does not limit or define the types of meetings that can be established, so that multiple meetings of multiple media types can be exchanged between terminal devices.

* Protocol convergence: SIP can provide convergence protocols for all services in the wireless group switching domain.

Commercial Value of SIP

* Revenue opportunities: new integrated multimedia services can be deployed in GORS, UMTS, XDSL, WLAN, and other independent domains for access. Therefore, operators can generate revenues before the release of 3GPP R5.

* Economic and efficient: Because SIP is an independent access protocol, wireless operators do not need to build infrastructure suitable for multiple access networks.

After a brief introduction, I believe everyone understands what the SIP protocol is. Hope to help you.
