Weighted Queuing
The Weighted Queuing feature allows the user to configure the priority scheme
between the internal priority queues as “Strict Priority” or to configure it as a
Weighted Round Robin (WRR) scheme, with user-configurable weights.
Note: If the queuing scheme commands are to be implemented on a P330-ML switch
other than the stack master, a session should be opened to the relevant switch.
Implementation of Weighted Queuing in the P330-ML
The user is able to set the Priority scheme to either “Strict” or “WWR.” The choice of
option impacts in the following way on the operation of the modules installed in the
stack.
• When the Priority scheme is set to “Strict”:
— Giga ports — the Low priority queue will transmit only if the High priority
queue has nothing to transmit.
• When the Priority scheme is set to”WWR” with a weight factor ‘n’:
— Giga ports — the High priority queue will transmit ‘n’ packets for each
packet that willbe transmitted from the Low priority queue.
Note: By default, the WWR weights between the high and low priority queues are
1:64.
