Bandwidth reservation or limitation (CBQ)
The reference value in Kbits/s or en Mbits/s allows indicating a reference on which bandwidth restrictions, indicated in percentage in the configuration of queues, will be based.
This value will restrict all traffic subject to QoS. The sum of all traffic passing through QoS will not be able to exceed this value and any excess network packets will be eliminated. It is therefore very important to set a reference value suited to the throughput of the network interface in question.
“ACK” and “low delay” packets are treated with a higher default priority (in order to speed up the transfer of data through limited bandwidth).
