Towards Fair and QoS-Aware Bandwidth Allocation in Next-Generation Multi-Gigabit WANs

The increasing demand for high-speed, reliable, and fair network services in multi-gigabit-wide area networks (WANs) has necessitated the development of advanced bandwidth allocation mechanisms. This paper proposes a Fair and QoS-Aware Dynamic Bandwidth Allocation (FQ-DBA) algorithm designed to address the dual challenges of fairness and Quality of Service (QoS) prioritisation in multi-gigabit networks. FQ-DBA dynamically allocates bandwidth to ensure equitable distribution among users while meeting the stringent QoS requirements of high-priority traffic, such as VoIP and video streaming. The algorithm integrates traffic classification, fairness enforcement, and QoS-aware allocation to optimise network performance. Simulation results demonstrate that FQ-DBA achieves a high fairness index, meets QoS guarantees, and maximises throughput while minimising latency. The proposed framework is scalable, energy-efficient, and compatible with existing network protocols, making it a promising solution for next-generation WANs.
