¢
Packets Submitted: The number of packets submitted by upper layers to this
connection.
¢ Packets Transmitted: The number of packets transmitted to the wireless port
through this connection, excluding retransmissions.
¢
Packets Dropped: The number of packets dropped from this connection due to
congestion in the wireless link. (identical to Packets Discarded).
¢ Packets Discarded: The number of packets discarded from this connection due
to congestion in the wireless link. (identical to Packets Dropped).
¢
Average Delay: The average packet delay in milliseconds, measured for this
connection over the last 15 seconds. The value is updated every 15 seconds.
¢ Delay Variance: The variance (the standard deviation squared) of the packet
delay, in milliseconds squared, measured for this connection over the last 15
seconds. The value is updated every 15 seconds.
¢ Maximum Delay: The maximum packet delay in milliseconds, measured for
this connection over the last 15 seconds. The value is updated every 15
seconds.
¢ Data Loss Indicator (%): The percentage of dropped packets, out of the total
demand, measured for this connection over the last 15 seconds. The value is
updated every 15 seconds.
DLI (%) = 100 * (Packets Dropped) / (Packets Submitted)
¢ CIR Utilization (%): The CIR utilization measured for an RT or NRT connection
over the last 15 seconds. Not applicable for BE and CG connections.
k = 100 x (the minimum between bytes transferred and CIR)/CIR is calculated
for each 1 second interval. CIR Utilization equals the average of k over the last
15 seconds, and may vary from 0 to 100. The value is updated every 15
seconds.
¢ EIR Utilization (%): Excess Information Rate utilization measured for a BE or
NRT connection over the last 15 seconds. Not applicable for RT and CG
connections.
