List the four main categories of QoS that were derived from ATM, and give the meaning of each.
What will be an ideal response?
ATM specifies the following four types of QoS categories:
? CBR (Constant Bit Rate): Data enters the flow at a fixed rate, such as data from a digitized
voice call entering at exactly 64 Kbps
? VBR (Variable Bit Rate): Data enters the flow at a variable rate within specified statistical
bounds
? ABR (Available Bit Rate): The flow agrees to use whatever data rate is available at a given time
? UBR (Unspecified Bit Rate): No bit rate is specified for the flow
