Key Bullet Points for H.323 Internet Protocol Telephony
Slide 1. The H.323 umbrella ITU recommendations sets standards for multimedia communications over LANs that are not QoS guaranteed. These include
Slide 2. H323 includes A) stand-alone devices, B) Embedded personal computer technology, C) Point-to-point and multipoint conferences, D) Call control, E) Multimedia management, E) Bandwidth management, and F) interfaces between LANs and other networks.
Slide 3. H.323 is comprehensive, flexible, and is applicable to VO handsets and full multimedia video-conferencing stations. Reasons why it is used for this article include:
Slide 4 Concrete and consistent standards for
* Existing IP-based networks that compensate for problems connected with variable LAN latency
* Developing of multimedia applications without changing their network infrastructure.
* Device-to-device, application-to-application, and vendor-to-vendor interoperability, as long as users develop around other H.323-compliant products.
Slide 5: The proposal adds a third layer of flexibility to H.323 by implementing a modified MA advanced architecture using IN provisioning constructs along with enablers such as MA, Jini/Java Beans. Such an addition is allowed and logical because
Slide 6: H.323 Codec gives architects, including the authors of this proposal --
* Standards for compression and decompression of audio and video data streams
* Assurance that equipment from different vendors will have some area of common support.
* Schemas for receiving clients to communicate capabilities to the sender,
using existing call setup and control protocols.
The ability to run on top of common network architectures.
Slide 7: This proposal creates an additional layer of flexibility based on these setup and control protocols. The proposal suggests two additions to the H.323 c
