Qos Scheduling Mechanism - D-Link DAS-3626 User Manual

QoS Scheduling Mechanism

Changing the output scheduling used for the hardware queues in the switch can customize QoS. As with any changes
to QoS implementation, careful consideration should be given to how network traffic in lower priority queues are
affected. Changes in scheduling may result in unacceptable levels of packet loss or significant transmission delays. If
you choose to customize this setting, it is important to monitor network performance, especially during peak demand,
as bottlenecks can quickly develop if the QoS settings are not suitable.

QoS Scheduling
This window allows the user to configure the way the switch will map an incoming packet per port based on its 802.1p
user priority, to one of the eight available hardware priority queues available on the switch.

Description
Enter the port or port list you wish to configure.
Strict – The highest class of service is the first to process traffic. That is, the highest class of
service will finish before other queues empty.
Weighted Round Robin – Use the weighted round-robin (WRR) algorithm to handle packets
in an even distribution in priority classes of service. For weighted round-robin queuing, the
number of packets sent from each priority queue depends upon the assigned weight.
