D-Link DES-3028 User Manual - Cos Output Scheduling

DES-3028 DES-3028P DES-3052 DES-3052P Layer 2 Fast Ethernet Managed Switch 

The Scheduling Mechanism has the following parameters. 

Parameter                      Description 

Strict 

Denoting a Strict scheduling will set the highest queue to be emptied first while the 

other queues will follow the weighted round-robin scheduling scheme. 

Weight Fair 

Use the weighted round-robin (WRR) algorithm to handle packets in an even 

distribution in priority classes of service. 

Click Apply to let your changes take effect. 

CoS Output Scheduling 

CoS can be customized by changing the output scheduling used for the hardware classes of service in the Switch. As with any 

changes to CoS implementation, careful consideration should be given to how network traffic in lower priority classes of service 

is affected. Changes in scheduling may result in unacceptable levels of packet loss or significant transmission delay. 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 CoS settings are not suitable. In the CoS folder, click CoS Output Scheduling, to view the window shown 

below.
