How is bandwidth allocated to traffic flows in a flow-based WFQ solution?

Flow-based Weighted Fair Queuing (WFQ) aims to provide fair bandwidth allocation to individual traffic flows. It classifies traffic into flows and then ensures that each flow receives a fair and equal share of the available bandwidth, preventing any single flow from starving others.

While WFQ can be combined with priority queuing, WFQ itself, by default, focuses on fairness among flows, not inherent priority for voice.

This describes a priority queuing mechanism, potentially combined with another queuing type for remaining traffic, but not the core principle of WFQ, which is fairness.

While QoS markings can influence how flows are treated within WFQ (e.g., by affecting weight or class-based WFQ), the fundamental principle of flow-based WFQ is dividing bandwidth equally among flows, not solely based on QoS markings to divide all bandwidth.
