Each Priority level can be set queue from 0 to 3. Scheduling Configuration item can setup the
type is from 1 to 3. Queue from 0 to 3 can set up their Queue Weight from 1 to 15.
[Example on using type1 (WRR) Scheduling Configuration]
For example, you can set the EFM modem to use Weighted Round-Robin (WRR) queuing that
specifies a relative weight of each queue. WRR uses a predefined relative weight for each
queue that determines the percentage of service time to services each queue before moving
on to the next queue. This prevents the head-of-line blocking that can occur with strict priority
queuing.
On the table of scheduling Configuration:
Queue 0 1 2 3
Type 1 WRR WRR WRR WRR
Weight 1 2 4 8
Setup the Weighted Round-Robin (Type 1) shares bandwidth by using scheduling weights 1, 2,
4 and 8 for queues 0 through 3 respectively.
VLAN Tag Priority:
Priority 0 1 2 3 4 5 6 7
Queue 1 0 0 1 2 2 3 3
