It is a collection of video codecs installed in desktop computers, and video switches individually connected to the existing data line infrastructure. As with a telephone call, the only thing a video codec needs to know to make a connection is the IP address, alias or terminal ID which acts like the telephone number of the receiving video codec. Multipoint conferencing, in most cases, still requires a video switch, but the ability to perform point to point conferencing without a video switch dramatically reduces the need for video switches. This architecture also allows video codecs and video switches to be added as needed without disrupting existing H.323 videoconferencing operations. As might be expected, the effectiveness of desktop videoconferencing will depend heavily on the capabilities of the originating institution's network.
Gatekeepers register clients and coordinate communications with other gatekeepers.
Bandwidth control for each network segment managed. Call management monitors H.323 calls, tracks rejected calls, accounts for use of WAN links and monitors other H.323 Components. Gateway Enables H.323 clients to communicate with H.320 systems. Multipoint Control Unit Negotiates multiple clients in a conference format. Benefits of H.323 Enables comprehensive flexible applications configuration for voice over IP, desktop videoconferencing, collaborative computing and electronic whiteboard applications.
