Abstract

With the advent of 5G and beyond, the mobile network operator is integrated with edge computing capabilities along with the cloud. This paradigm requires the application at UE to consist of multiple microservices that are appropriately placed at the edge/cloud with dynamic relocation to enhance the overall Quality of Service (QoS) of the application. In this work, a Microservice-Scheduler is developed to dynamically relocate an application’s microservices between the edge and cloud server. The relocation decision is based on the CPU utilization of the edge server. The developed Microservice-Scheduler is integrated in ETSI compliant 5G testbed. The deployment is evaluated by analyzing the different scenarios obtained while monitoring the completion time of the microservices. It is observed that in the majority of scenarios, relocating microservices between the edge and cloud server outperforms the edge-only and cloud-only approaches. In addition, the dynamic relocation mechanism aids in better utilization of the resources while enhancing the overall QoS of the application’s microservices.

利用边缘-云连续性在 5G 网络中动态提供微服务

随着 5G 及更先进技术的出现，移动网络运营商将边缘计算能力与云相结合。这种模式要求 UE 上的应用由多个微服务组成，这些微服务被适当地放置在边缘/云上，并进行动态重新定位，以提高应用的整体服务质量（QoS）。在这项工作中，开发了一种微服务调度程序，用于在边缘和云服务器之间动态重新定位应用程序的微服务。迁移决策基于边缘服务器的 CPU 利用率。开发的微服务调度程序集成在符合 ETSI 标准的 5G 测试平台中。通过分析监测微服务完成时间时获得的不同场景，对部署进行了评估。据观察，在大多数场景中，在边缘和云服务器之间重新定位微服务的效果优于仅在边缘和仅在云的方法。此外，动态重新定位机制有助于更好地利用资源，同时提高应用程序微服务的整体服务质量。
