Figure 4.126 – QoS > Basic Settings > Port Scheduler Method
The fields that can be configured are described below:
From Port / To Port:
Select the appropriate port range used for the configuration here.
Scheduler Method:
Select the scheduler method that will be applied to the specified port(s). Options to
choose from are Strict Priority (
SP
), and Weighted Round-Robin (
WRR
). By default, the output queue
scheduling algorithm is
WRR
.
SP -
To set a CoS queue in the
SP
mode, any higher priority CoS queue must also be in the strict
priority mode.
WRR - WRR
operates by transmitting permitted packets into the transmit queue in a round robin
order. Initially, each queue sets its weight to a configurable weighting. Every time a packet from a
higher priority CoS queue is sent, the corresponding weight is subtracted by 1 and the packet in the
next lower CoS queue will be serviced. When the weight of a CoS queue reaches zero, the queue
will not be serviced until its weight is replenished. When weights of all CoS queues reach 0, the
weights get replenished at a time.
