利用5G SDWN和多层资源管理的协同作用进行网络优化
Leveraging Synergy of 5G SDWN and Multi-Layer Resource Management for Network Optimization
摘要：
第五代（5G）蜂窝无线网络被设想为预先配置面向服务的、灵活的和频谱/节能的边缘到核心基础设施，旨在提供多样化的应用。软件定义网络（SDN）、与多种无线电接入技术（RAT）兼容的软件定义无线电（SDR）以及5G软件定义无线网络（5G-SDWN）概念上的虚拟化的融合是提供这种动态网络的有前景的方法。5G-SDWN框架背后的主要技术是从深层核心实体到边缘无线接入点（AP）的控制和数据平面的分离。这种分离允许将资源抽象为5G-SDWN上的每个用户的传输参数。在这个以用户为中心和面向服务的环境中，资源管理对于实现效率和可靠性起着至关重要的作用。然而，很自然地想知道是否可以利用5G-SDWN来实现对资源组合的融合多层资源管理，以及CML资源管理是否可以有效地为5G-SDWN提供性能增强和可靠性。我们认为，回答这些问题并调查这种相互协同作用对于5G-SDWN来说并不是微不足道的，而是多维和复杂的，它由不同的技术组成，并继承了传统的几代无线网络。在本文中，我们提出了一种基于5G-SDWN的三大支柱的灵活协议结构，它可以以更跨层的方式处理所有所需的功能。在此基础上，我们展示了CML资源管理的一般框架如何控制最终用户的体验质量。针对5G-SDWN的两种场景，我们研究了通过CML资源管理联合用户关联和资源分配以提高虚拟化网络性能的效果。
英文摘要：
Fifth-generation (5G) cellular wireless networks are envisioned to predispose service-oriented, flexible, and spectrum/energy-efficient edge-to-core infrastructure, aiming to offer diverse applications. Convergence of software-defined networking (SDN), software-defined radio (SDR) compatible with multiple radio access technologies (RATs), and virtualization on the concept of 5G software-defined wireless networking (5G-SDWN) is a promising approach to provide such a dynamic network. The principal technique behind the 5G-SDWN framework is the separation of the control and data planes, from the deep core entities to edge wireless access points (APs). This separation allows the abstraction of resources as transmission parameters of each user over the 5G-SDWN. In this user-centric and service-oriented environment, resource management plays a critical role to achieve efficiency and reliability. However, it is natural to wonder if 5G-SDWN can be leveraged to enable converged multi-layer resource management over the portfolio of resources, and reciprocally, if CML resource management can effectively provide performance enhancement and reliability for 5G-SDWN. We believe that replying to these questions and investigating this mutual synergy are not trivial, but multidimensional and complex for 5G-SDWN, which consists of different technologies and also inherits legacy generations of wireless networks. In this paper, we propose a flexible protocol structure based on three mentioned pillars for 5G-SDWN, which can handle all the required functionalities in a more crosslayer manner. Based on this, we demonstrate how the general framework of CML resource management can control the end user quality of experience. For two scenarios of 5G-SDWN, we investigate the effects of joint user-association and resource allocation via CML resource management to improve performance in a virtualized network.
