Real-time Collaborative Editors (RCEs) are popular distributed applications that permit large and dynamic groups of collaborators to share and update large multimedia documents across many sites in real time. However, the state-of-the-art models are either locally centralized or globally distributed using a central cloud server to keep shared data synchronized. Multi-access Edge Computing (MEC) is an emergent architecture designed to bring storage, control and communication capabilities near to end devices, thus allowing real-time and resource extensive applications to be easily executed on low-capability handheld devices. This paper presents EdgeDoc, an edge-based RCE. Mobiles that are managed by the same edge node are cloned in the edge to offload resource-intensive tasks, whereas only lightweight edition components are handled locally. This provides a more effective solution to manage concurrency and collaboration on mobile devices. To evaluate the performance of the proposed system, a series of experiments were conducted, which show that EdgeDoc reduces latency by around 96%, thereby improving the responsiveness of RCE.

实时协作编辑器（RCE）是流行的分布式应用程序，允许大型和动态的协作者组在许多站点之间实时共享和更新大型多媒体文档。但是，最新模型是使用中央云服务器在本地集中或全局分布的，以保持共享数据同步。多访问边缘计算（MEC）是一种新兴的体系结构，旨在将存储，控制和通信功能带到终端设备附近，从而允许在低容量手持设备上轻松执行实时和资源丰富的应用程序。本文介绍EdgeDoc，它是基于边缘的RCE。由同一边缘节点管理的移动设备会在边缘克隆，以减轻资源密集型任务的负担，而只有轻量级版本组件才能在本地处理。这为管理移动设备上的并发和协作提供了更有效的解决方案。为了评估所提出系统的性能，进行了一系列实验，这些实验表明EdgeDoc将等待时间减少了约96％，从而提高了RCE的响应速度。
