User-Side Service Synchronization in Multiple Devices Environment

摘要

Today, a single user owning multiple devices is a reality. Moreover, with the advent of the concept of Everything-as-a-Service (XaaS), a cloud-based term that allows for a wide variety of services and applications deployed by the user, the multiple devices scenario gain more relevance, mainly due to the lack of interoperability between operating systems and services of these devices. We focus on multiple device's environments for synchronizing web services at the client-side without continuously depending on a cloud-based system. We discuss a model-based architecture that allows us to fluently migrate services/data and sessions from one device to another regardless of the operating system. The architecture, called The CUBE [12], is based on user-centric principles combined with REST and RESTful concepts. In this extension paper, we present two main contributions. First, with a description of technical and conceptual aspects of the CUBE, and its relation with the devices/applications and web services. Then, a feasibility test for a tight-coupling service such as YouTube streaming. Within a set of ten users, we presented preliminary results that had measured the wasted time to play a given video with and without the CUBE towards five different devices. The results demonstrate that when the users used the CUBE, they spend only 5.821 s to migrate the video, while without the CUBE, they spend 68.101 s to do the same procedure. That means the CUBE is up to ～12 times faster than the traditional YouTube cloud-based synchronization procedure.
