Enhanced Distributed Bandwidth Allocation Algorithm for Network Latency Reduction in IEEE 802.17 Rings

The IEEE 802.17 Resilient Packet Ring (RPR) technology is a cornerstone for the rapid expansion of metropolitan digital infrastructure. It is recognized for its robustness and spatial reuse capabilities. However, under highly dynamic and asymmetric traffic loads, standard RPR fairness algorithms often suffer from bandwidth oscillations, leading to unpredictable queuing delays and increased network latency. To address this limitation, this study introduces an Enhanced Distributed Bandwidth Allocation (EDBA) algorithm designed specifically for network latency reduction. By incorporating a filtered transit queue length into the fair rate calculation, EDBA dynamically calibrates bandwidth allocation at the source nodes before congestion propagates across the transit paths. Performance evaluations via network simulations demonstrate that the proposed algorithm significantly reduces average packet latency by up to 94%, while maintaining fairness and high throughput across the ring topology.
