Scheduling
Scheduling arbitrates among multiple queues waiting to transmit a frame. The Brocade switch
supports both Strict Priority (SP) and Deficit Weighted Round Robin (DWRR) scheduling algorithms.
Also supported is the flexible selection of the number of traffic classes using SP-to-DWRR. When
there are multiple queues for the same traffic class, then scheduling takes these equal priority
queues into consideration.
For an overview of the supported scheduling algorithms, refer to the Network OS Administrator’s
Guide.
Scheduling the QoS queue
To specify the schedule used, perform the following steps.
1. Issue the RPC to configure the node in the
urn:brocade.com:mgmt:brocade-qos namespace.
2. Under the node, include the // hierarchy of
element nodes.
3. Under the node, include the following leaf elements.
a. In the element, set the number of traffic classes to be part of the strict
priority Traffic Class. For example, if the priority number is 3, the strict priority Traffic Class
contains Traffic Classes 7, 6, and 5.
b. In the element, specify “dwrr” for deficit weighted round robin queues.
