the Peak Cell Rate field is displayed. Specify a required value (in

CBR
(Constant Bit Rate): This service is used for applications that
require a constant data rate. It is mostly used for transferring
uncompressed audio and video, e.g. videoconferencing, interactive
audio (telephony), audio/video distribution (television, distance
education, e-shops), and retrieval (video-on demand, audio
libraries). When you select this value from the drop-down list, the
Peak Cell Rate field is displayed. Specify a required value (in
cells per second).
Non Realtime VBR
(Non-Real-time Variable Bit Rate): This service can be used for
transferring data that have critical response-time requirements, e.g.
air ticket booking, bank transactions, and process monitoring. When
you select this value from the drop-down list, the Peak Cell Rate,
Sustainable Cell Rate, and Maximum Burst Size fields are
displayed. Specify required values.
Realtime VBR
(Real-time Variable Bit Rate): This service is used for delay-
sensitive applications such as real time video. The Rt-VBR provides
higher network flexibility than the CBR service. When you select
this value from the drop-down list, the Peak Cell Rate,
Sustainable Cell Rate, and Maximum Burst Size fields are
displayed. Specify required values.
