D-Link DES-3250TG Standalone Layer 2 Switch
(QOS Output) Scheduling
Click QoS on the Configuration menu, and then click scheduling:
Figure 6- 35. QoS Output Scheduling window
The Max. Packets(O-255) field specifies the number of packets that a queue will transmit before
surrendering the transmit buffer to the next lower priority queue in a round-robin fashion.
The Max. Latency(0-255) field specifies the maximum amount of time that a queue will have to wait
before being given access to the transmit buffer. The Max. Latency(0-255) is a priority queue timer.
When it expires, it overrides the round-robin and gives the priority queue that it was set for access to
the transmit buffer.
There is a small amount of additional latency introduced because the priority queue that is transmitting
at the time the Max. Latency(0-255) time expires will finish transmitting its current packet before giving
up the transmit buffer.
