Edge networking has become an important technology for providing low-latency services to end users. However, deploying an edge network does not guarantee continuous service for mobile users. Mobility can cause frequent interruptions and network delays as users leave the initial serving edge. In this paper, we propose a solution to provide transparent service continuity for mobile users in large-scale WiFi networks. The contribution of this work has three parts. First, we propose ARNAB architecture to achieve mobile service continuity. The term ARNAB means rabbit in Arabic, which represents an Architecture for Transparent Service Continuity via Double-tier Migration. The first tier migrates user connectivity, while the second tier migrates user containerized applications. ARNAB provides mobile services just like rabbits hop through the WiFi infrastructure. Second, we identify the root-causes for prolonged container migration downtime. Finally, we enhance the container migration scheme by improving system response time. Our experimental results show that the downtime of ARNAB container migration solution is 50% shorter than that of the state-of-the-art migration.

跨协调的边缘网络实现移动服务连续性

边缘网络已成为为终端用户提供低延迟服务的重要技术。然而，部署边缘网络并不能保证为移动用户提供持续服务。当用户离开最初的服务边缘时，移动性会导致频繁的中断和网络延迟。在本文中，我们提出了一种解决方案，为大规模 WiFi 网络中的移动用户提供透明的服务连续性。这项工作的贡献分为三个部分。首先，我们提出了 ARNAB 架构来实现移动服务的连续性。术语 ARNAB 在阿拉伯语中意为兔子，它代表通过双层迁移实现透明服务连续性的架构。第一层迁移用户连接，而第二层迁移用户容器化应用程序。ARNAB 提供移动服务，就像兔子在 WiFi 基础设施中跳跃一样。其次，我们确定了容器迁移停机时间延长的根本原因。最后，我们通过提高系统响应时间来增强容器迁移方案。我们的实验结果表明，ARNAB 容器迁移解决方案的停机时间比最先进的迁移方案的停机时间短 50%。
