Prioritized Multi-Tenant Traffic Engineering for Dynamic QoS Provisioning in Autonomous SDN-OpenFlow Edge Networks
CoRR(2024)
摘要
This letter indicates the critical need for prioritized multi-tenant
quality-of-service (QoS) management by emerging mobile edge systems,
particularly for high-throughput beyond fifth-generation networks. Existing
traffic engineering tools utilize complex functions baked into closed,
proprietary infrastructures, largely limiting design flexibility, scalability,
and adaptiveness. Hence, this study introduces a software-defined networking
(SDN)-based dynamic QoS provisioning scheme that prioritizes multi-tenant
network traffic while focusing on the base station-edge cloud scenario. The
designed scheme first separates control and data planes and enables traffic
management automation using SDN programmability. It then implements dynamic QoS
management via the SDN-OpenFlow protocol, which ensures ample bandwidth for
multiple priority flows and efficiently manages the remaining bandwidth for
non-priority traffic. Empirical experiments are conducted with a Mininet
network emulator and an OpenDayLight controller. Performance evaluation
validates the proposed scheme's effectiveness in meeting multi-tenant QoS
criteria, offering a robust solution for traffic prioritization in SDN-based
edge networks.
