QoS | CAR, CIR, MIR, EIR, PIR, CDR
Committed Access Rate (CAR) is used to limit traffic that can enter or exit an interface.
Committed Information Rate (CIR) is minimum bandwidth that is guaranteed to work under normal conditions, at any time the bandwidth should not fall below.
Minimum Information Rate (MIR) is minimum bandwidth, the lowest information rate will be assigned where there is congestion.
Excess Information Rate (EIR) is burstable bandwidth, CIR plus excess burst rate.
Peak Information Rate (PIR) is bandwidth will may use during data bursts when there is excess bandwidth available and no congestion also mention maximum information rate (MaxIR/MIR).
Committed Data Rate (CDR) refers also to voice and non-data packets and not only to data packets as in CDR.
All rate figure in kilobits per second (kbit/s).
