Lisa Bock covers H.323, which acts as a wrapper for media control using Q.931, H.225, and H.245. An H.323 network is made up of endpoints or terminals, a gateway, Multipoint Control Unit, gatekeeper, and back-end Service.
- [Instructor] H.323 Signaling is an ITU-T recommendation…for audio and video communication across an IP network.…H.323 acts as a wrapper for media control…and includes H.225, H.245, which are both protocols…that have a specific role in the call setup process.…An H.323 network is made of several components,…such as end points or terminals, a gateway,…and a a multipoint control unit.…
This is used to bridge videoconferencing calls,…and it includes a multipoint controller…for call signaling, and a multipoint processor…to mix, encode, and switch streams.…Then there's the gatekeeper and a back-end service…which holds information about terminals,…configuration, and billing.…The gatekeepers are very useful as they serve as a bridge…between the H.323 network and the outside world.…
The gatekeepers provide address resolution…and bandwidth control.…An H.225 signal establishes communications…between two hosts, which is initiated…either using a TCP or UDP connection…with an H.225 signal.…This contains the registration admission status protocol…
