DESCRIPTION
Select to enable or disable this queue.
Enter a descriptive name of up to 15 printable English keyboard
characters, including spaces.
Select the interface to which this queue is applied.
Select the priority level (from 1 to 4) of this queue.
The smaller the number, the higher the priority level. Traffic assigned to
higher priority queues gets through faster while traffic in lower priority
queues is dropped if the network is congested.
Select the weight (from 1 to 8) of this queue.
If two queues have the same priority level, the CellPipe 7130 RG divides
the bandwidth across the queues according to their weights. Queues with
larger weights get more bandwidth than queues with smaller weights.
This field displays Drop Tail (DT). Drop Tail (DT) is a simple queue
management algorithm that allows the CellPipe 7130 RG buffer to accept
as many packets as it can until it is full. Once the buffer is full, new
packets that arrive are dropped until there is space in the buffer again
(packets are transmitted out of it).
As of writing, this is set to PQWFQ by default. This stands for Priority
Queue Weighted Fair Queuing, which is a packet-based scheduling
algorithm that allocates more bandwidth to critical applications.
