QoS > QoS Settings
Network traffic is usually unpredictable and the only basic
assurance that can be offered is best effort traffic delivery.
To overcome this challenge, Quality of Service (QoS)
is applied throughout the network. This ensures that
network traffic is prioritized according to specified criteria,
and that specific traffic receives preferential treatment.
QoS in the network optimizes network performance and
entails two basic facilities:
Classifying incoming traffic into handling classes, based
on an attribute, including:
The ingress interface•
Packet content
A combination of these attributes
Providing various mechanisms for determining the
allocation of network resources to different handling
classes, including:
The assignment of network traffic to a particular
hardware queue
The assignment of internal resources
You can set the Switch to service the queues based on
a strict rule that requires all traffic in a higher priority
queue to be processed before lower priority queues are
serviced, or use Weighted Round-Robin (WRR) queuing
that specifies a relative weight of each queue. WRR
uses a pre-defined relative weight for each queue that
determines the percentage of service time the Switch
services each queue before moving on to the next queue.
This prevents the head-of-line blocking that can occur
with strict priority queuing.
QoS > QoS Settings
Queue Mode
Set the Queue Mode to Strict Priority or WRR.
Strict Priority Services the egress queues in sequential
order, transmitting all traffic in the higher priority queues
before servicing lower priority queues.
WRR Weighted Round-Robin shares bandwidth at the
egress ports by using scheduling weights 1, 2, 4, 8 for
queues 1 through 4 respectively.
WRR Weight Displays the WRR weights to queues.
