When not in congestion, does WFQ act as FIFO?
When not in congestion, does WFQ act as FIFO?
Not really. If there is very little traffic WFQ behaves similar to FIFO. Even if there is no congestion, queuing may exist depending on how bursty the incoming traffic is. Two queues with different weights may have one or more packets and it is not obvious that an earlier-arriving packet will get servicedfirst.
