Queuing Mechanism – Type 1
Setting
Description
Factory
Default
Weight Fair
The Weidmüller switch has 4 priority queues. In the weight
fair scheme, an 8, 4, 2, 1 weighting is applied to the four
priorities. This approach prevents the lower priority frames
from being starved of opportunity for transmission with only
a slight delay to the higher priority frames.
Weight Fair
Strict
In the Strict-priority scheme, all top-priority frames egress a
port until that priority’s queue is empty, and then the next
lower priority queue’s frames egress. This approach can
cause the lower priorities to be starved of opportunity for
transmitting any frames but ensures that all high priority
frames will egress the switch as soon as possible.
