为了解决5G网络中的频谱短缺和提高资源利用率，网络切片是一种很有前途的技术，可以在不需要额外基础设施投资的情况下建立端到端虚拟网络。通过利用软件定义网络(SDN)和网络功能虚拟化(NFV)，我们可以实现完全隔离和专用的切片，以满足用户不同的服务质量(QOS)先决条件和服务级别协议(SLA)。本文侧重于将网络切片体系结构应用于现实世界场景所带来的技术和经济挑战。我们考虑这样一个市场，其中多个网络提供商(NP)拥有物理基础设施，并将其资源提供给多个服务提供商(SP)。然后，SP将这些资源作为切片提供给其关联的用户。我们提出了一个网络切片市场的整体迭代模型，以及一个收敛到稳健的ϵ竞争均衡的时钟拍卖。在市场的每个周期结束时，切片都会重新配置，SP的目标是了解其用户的私有参数。数值结果验证和评估了时钟拍卖的收敛和所提出的市场结构表达系统不同主体的激励的能力。
Towards addressing spectral scarcity and enhancing resource utilization in 5G networks, network slicing is a promising technology to establish end-to-end virtual networks without requiring additional infrastructure investments. By leveraging Software Defined Networks (SDN) and Network Function Virtualization (NFV), we can realize slices completely isolated and dedicated to satisfy the users’ diverse Quality of Service (QoS) prerequisites and Service Level Agreements (SLAs). This paper focuses on the technical and economic challenges that emerge from the application of the network slicing architecture to real-world scenarios. We consider a market where multiple Network Providers (NPs) own the physical infrastructure and offer their resources to multiple Service Providers (SPs). Then, the SPs offer those resources as slices to their associated users. We propose a holistic iterative model for the network slicing market along with a clock auction that converges to a robust ϵ-competitive equilibrium. At the end of each cycle of the market, the slices are reconfigured and the SPs aim to learn the private parameters of their users. Numerical results are provided that validate and evaluate the convergence of the clock auction and the capability of the proposed market architecture to express the incentives of the different entities of the system.
