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.

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.
