Weighted fair queueing

Weighted Fair Queueing (WFQ) is a network scheduling algorithm used to manage bandwidth allocation among different flows or streams of data in a network. It is a refinement of the basic fair queues, and it aims to provide proportional bandwidth distribution while ensuring that lower-priority flows do not starve. ### Key Features: 1. **Fairness**: WFQ ensures that each flow receives a fair share of the available bandwidth based on its weight.
