The Internet of Things (IoT) has introduced advanced vertical use cases in many sectors such as smart factories and smart cities. Most of the use cases are managed by a cloud-based IoT service layer platform that may affect the quality of service due to network communication latency. The early concept of edge computing has proven significant results in scheduling lightweight tasks for edge nodes and highly computational resources for the cloud. To support latency-critical IoT services, we propose an interworking architecture between the IoT service layer platform and Multi-Access Edge Computing (MEC) at the network edge. The core idea of our architecture is to virtualize and instantiate required IoT service functions to the edge of the network, close to IoT devices that need ultra-low latency and high bandwidth. The interworking architecture is designed based on two global standards: oneM2M for IoT and MEC for edge computing. We present MEIX, a system based on such standardized techniques, and show how it can support mission-critical IoT services at the edge nodes. MEIX introduces a novel component that enables running virtual IoT common service functions to support the interoperability of IoT platform and network functions on top of MEC-based systems.

MEIX：为工业物联网服务发展多接入边缘计算

物联网 (IoT) 在智能工厂和智能城市等许多领域引入了先进的垂直用例。大多数用例由基于云的物联网服务层平台管理，可能会因网络通信延迟而影响服务质量。边缘计算的早期概念已经证明在为边缘节点调度轻量级任务和为云计算高计算资源方面取得了显着的成果。为了支持对延迟至关重要的物联网服务，我们提出了物联网服务层平台与网络边缘的多接入边缘计算 (MEC) 之间的互通架构。我们架构的核心思想是将所需的物联网服务功能虚拟化和实例化到网络边缘，靠近需要超低延迟和高带宽的物联网设备。互通架构基于两个全球标准设计：用于物联网的oneM2M和用于边缘计算的MEC。我们展示了 MEIX，一个基于此类标准化技术的系统，并展示了它如何在边缘节点支持关键任务物联网服务。MEIX 引入了一个新颖的组件，可以运行虚拟物联网公共服务功能，以支持基于 MEC 的系统之上的物联网平台和网络功能的互操作性。
