What is H.323?

3 Answers

Its a gateway control protocol developed by ITU-T. It is a suite of protocol.

H.323 is a standard for VOIP. It was originally developed to allow video conferencing network traffic to be carried over IP, but it rapidly was co-opted into the VOICE over IP movement. It really allowed voice over IP to happen. At this point, h.323 has to be in a network that wants to deploy/use voip phones. It's often used in conjunction with a QoS environment, because the H323 uses UDP, not TCP, and is therefore a 'best effort' delivery. THe network has to provide an environment that prevents packet loss or jitter...and that's what QOS is about

H.232 is an Internet Protocol used in Demand Circuit Networks like: Frame Relay, ATM. It can also be used in Ethernet, TCP/UDP/IP. Mainly used in the inter-network conferencing. H.323 has Four Components: Gateway | Gatekeepers | Terminal and MCU ( Multipoint Control Unit). Mainly used in VoIP technology. Regards, Raja. V
