zService Category – Five classes of traffic defined are defined:
— UBR Without PCR (Unspecified Bit Rate without Peak Cell Rate)
— UBR With PCR (Unspecified Bit Rate with Peak Cell Rate) – UBR
service is suitable for applications that can tolerate variable delays
and some cell loss, such as data transfer, messaging, distribution, and
retrieval, and remote terminal applications such as telecommuting.
— CBR (Constant Bit Rate) – Used by applications that require a fixed
data rate that is continuously available during the connection time. It
is commonly used for uncompressed audio and video information
such as videoconferencing, interactive audio (telephony), and audio
and video distribution and retrieval.
— Non-Realtime VBR (Non-Real-time Variable Bit Rate) – Can be used
for data transfers that have critical response-time requirements such
as airline reservations, banking transactions, and process monitoring.
— Realtime VBR (Real-time Variable Bit Rate) – Used for
time-sensitive applications such as real-time video. Rt-VBR service
allows the network more flexibility than CBR.
