With the big success of the Cloud Computing, or the Cloud, new research areas appeared. Edge Computing (EC) is one of the recent paradigms that is expected to overcome the Quality of Service (QoS) and latency issues caused by the best-effort behaviour of the Cloud. EC aims to bring the computation power close to the end devices as much as possible and reduce the dependency to the Cloud. Bringing computing power close to the source also enables real-time applications. In this paper, we propose a novel software reference architecture for Edge Servers, which is operating system (OS) and hardware-agnostic. Edge Servers can collaborate and execute (near) real-time tasks on time, either by downscaling or scheduling them according to their deadlines or offloading them to other Edge Servers in the network. Decision making for offloading, resource planning, and task scheduling are challenging problems in decentralized systems. The paper explains how resource planning and task scheduling can be overcome with software approach. Finally, the article realises the architecture as a framework, called Real-Time Edge Framework (RTEF) and validates its correctness with a use case.

随着云计算或云计算的巨大成功，出现了新的研究领域。边缘计算（EC）是有望克服由云的尽力而为行为引起的服务质量（QoS）和延迟问题的最新范例之一。EC的目标是使计算能力尽可能接近终端设备，并减少对云的依赖。将计算能力带到源头附近还可以实现实时应用。在本文中，我们为边缘服务器提出了一种新颖的软件参考体系结构，该体系结构是操作系统（OS）和与硬件无关的。边缘服务器可以按时限缩减规模或安排时间，或者将其卸载到网络中的其他边缘服务器，从而按时协作并执行（接近）实时任务。卸载决策，资源计划，任务调度是分散系统中的难题。本文介绍了如何通过软件方法克服资源计划和任务计划。最后，本文将架构实现为称为实时边缘框架（RTEF）的框架，并通过用例验证其正确性。
