Software-defined networking for service-oriented 5G networks

下一代（5G）无线网络预计将适应具有不同服务质量要求的各种新兴服务，例如机器对机器通信、物联网、车辆通信和智能电网。该网络将整合各种网络资源和技术，以支持高传输速率，并提高移动的用户的体验质量。传统的“一刀切”的网络架构由于可扩展性差、适应性和可扩展性有限，无法有效地满足不同业务的需求。该研究项目旨在通过利用软件定义网络的概念，为5G系统的敏捷和灵活的网络基础设施研究和开发新的工程解决方案。我们将专注于专用的虚拟分层网络架构，以有效支持未来5G网络中的移动的通信。特别是，我们将定义虚拟网络拓扑结构，研究如何体现一个虚拟网络的物理网络，以及如何适应数据流量负载动态，并开发新的网络协议，以确保服务质量的端到端的数据传输，并有效地利用网络资源。

The next generation (5G) wireless network is expected to accommodate a wide range of emerging services with diverse service quality requirements, such as in machine-to-machine communication, internet of things, vehicular communications, and smart grid. The network will integrate a variety of network resources and technologies to support high transmission rate and to enhance quality of experience to mobile users. The traditional one-size-fits-all network architecture cannot efficiently meet the needs of different services, due to the poor scalability, limited adaptability, and inflexibility. This research project is to investigate and develop new engineering solutions for an agile and flexible networking infrastructure for the 5G systems, by exploiting the concept of software defined networking. We will focus on a dedicated virtually layered network architecture to efficiently support mobile communications in the future 5G network. In particular, we will define virtual network topology, investigate how to embody a virtual network to the physical network and how to adapt to the data traffic load dynamics, and develop novel networking protocols to ensure service quality in end-to-end data transport and to efficiently utilize network resources.
