Excess Information Rate utilization measured for a BE or NRT connection over the last 15 seconds. Not applicable for RT and CG connections. k=100 x (bytes transferred-CIR)/(MIR-CIR) is calculated for each 1 second interval. In BE CIR = 0. The EIR Utilization equals the average of k over the last 15 seconds, and may range from 0 to 100. The value is updated every 15 seconds.
