In the area which is data communications protocol defined rules planned exchanging data between two or more parties.
VoIP (voice over Internet Protocol) to a communication technology that allows voice/data bits, exchanged between voice and data networks. Therefore must be certain protocols for its operations. In this context, there are many popular protocols namely h. 323, SIP (Session Initiation Protocol) and MGCP (Media Gateway Control Protocol). H. 323 is most common under these protocols used and widely-used Protocol VoIP.
Structure of the Protocol
- Each protocol has a structure that defines the most important features within.
H. h.323 protocol has a structure that contains multiple sub protocols with four protocols as important elements. This is DVB/RTP (digital video broadcasting/real time protocol) 225, the h. 245 and the H. 239. This text data in applications, real time voice and video uses, such as voice chat or video conference, 225 transfer creation and termination of h. 245 and active connections for control and supervision of operations House, DVB/RTP H. 239.
Network elements
A VoIP network based on the h. 323 specification contains the following important network elements in architecture: terminals, MCU (multipoint control unit), gateway and wake up. A Terminal is just a series of computer/phone while h. h.323 protocol is installed, while processed MCU requests for transmission of voice/video/text from multiple terminals simultaneously. In addition, a gateway is an entity of ZusammenschaltungMarlant serves as a cross between VoIP and other networks (such as telephone and computer networks), with the guards as part of allgemeinen control of this network installed.
Applications
Also obvious. H. its large VoIPtravaux is 323 competition. Other applications of h. 323 include chat, voice conferencing sessions and online video/audio streaming through computer networks. These rich applications are a versatile and highly recommended protocol for multimedia operations h. 323.
