The increasing number of heterogeneous devices connected to the Internet, together with tight 5G requirements have generated new challenges for designing network infrastructures. Industrial verticals such as automotive, smart city and eHealthcare (among others) need secure, low latency and reliable communications. To meet these stringent requirements, computing resources have to be moved closer to the user, from the core to the edge of the network. In this context, ETSI standardized Multi-Access Edge Computing (MEC). However, due to the cost of resources, MEC provisioning has to be carefully designed and evaluated. This survey firstly overviews standards, with particular emphasis on 5G and virtualization of network functions, then it addresses flexibility of MEC smart resource deployment and its migration capabilities. This survey explores how the MEC is used and how it will enable industrial verticals.

在 5G 中实现工业垂直：关于基于 MEC 的配置和灵活性方法的调查

越来越多的异构设备连接到互联网，加上严格的 5G 要求，为设计网络基础设施带来了新的挑战。汽车、智慧城市和电子医疗等垂直行业需要安全、低延迟和可靠的通信。为了满足这些严格的要求，计算资源必须更靠近用户，从网络的核心到边缘。在这种情况下，ETSI 标准化了多接入边缘计算 (MEC)。然而，由于资源成本，必须仔细设计和评估 MEC 配置。本次调研首先对标准进行了概述，特别强调了 5G 和网络功能的虚拟化，然后探讨了 MEC 智能资源部署的灵活性及其迁移能力。
