The communication network context in actual systems like 5G, cloud and IoT (Internet of Things), presents an ever-increasing number of users, applications and services that are highly distributed with distinct and heterogeneous communications requirements. Resource allocation in this context requires dynamic, efficient and customized solutions and Bandwidth Allocation Models (BAMs) are an alternative to support this new trend. This paper proposes the BAMSDN (Bandwidth Allocation Model through Software-Defined Networking) framework that dynamically allocates resources (bandwidth) for a MPLS (MultiProtocol Label Switching) network using a SDN (Software-Defined Networking)/OpenFlow strategy with BAM. The framework adopts an innovative implementation approach for BAM systems by controlling the MPLS network using SDN with OpenFlow. Experimental results suggest that using SDN/OpenFlow with BAM for bandwidth allocation does have effective advantages for MPLS networks requiring flexible resource sharing among applications and facilitates the migration path to a SDN/OpenFlow network.

基于带宽分配模型的动态资源分配SDN/OpenFlow框架


5G、云和物联网等实际系统中的通信网络环境呈现出数量不断增加的用户、应用程序和服务，这些用户、应用程序和服务高度分布，具有独特且异构的通信需求。这种情况下的资源分配需要动态、高效和定制的解决方案，而带宽分配模型 (BAM) 是支持这一新趋势的替代方案。本文提出了 BAMSDN（通过软件定义网络的带宽分配模型）框架，该框架使用 SDN（软件定义网络）/OpenFlow 策略和 BAM 为 MPLS（多协议标签交换）网络动态分配资源（带宽）。该框架采用创新的 BAM 系统实现方法，通过使用 SDN 和 OpenFlow 控制 MPLS 网络。实验结果表明，使用带有 BAM 的 SDN/OpenFlow 进行带宽分配对于需要在应用程序之间灵活共享资源的 MPLS 网络确实具有有效的优势，并且有利于向 SDN/OpenFlow 网络的迁移路径。
