Asynchronous Transfer Mode: ABR and CBR
Available Bit Rate (ABR)
Network ATM transfer characteristis may change after connecting
User adapts its traffic to changes to expereience low cell loss ratio
Not intended for real-time applications
User specifies a maximum bandwidth (Peak Cell Rate) and minimum useable bandwidth (Minimum Cell Rate)
Constant Bit Rate (CBR)
Network provides consistent quantity of bandwidth
Intended for real-time applications
