This attribute indicates the committed burst size (bc) in bits. bc is the amount of data that the network agrees to transfer under normal conditions over a measurement interval (t). bc is used for data with Discard Eligibility indication DE=0. DE=1 data does not use bc at all, excessBurstSize if is used instead. This attribute should be ignored when rateEnforcement is off.
