LABEL DESCRIPTION
Active Select to enable or disable this queue.
Name Enter the descriptive name of this queue.
To Interface Select the interface to which this queue is applied.
This field is read-only if you are editing the queue.
Priority Select the priority level (from 1 to 3) 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.
Weight Select the weight (from 1 to 8) of this queue.
If two queues have the same priority level, the VDSL Router divides the bandwidth
across the queues according to their weights. Queues with larger weights get more
bandwidth than queues with smaller weights.
Buffer
Management This field displays Drop Tail (DT). Drop Tail (DT) is a simple queue management
algorithm that allows the VDSL Router 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).
Rate Limit Specify the maximum transmission rate (in Kbps) allowed for traffic on this queue.
