“…The goal of the demo is to demonstrate the seamless mobility offered by the ORCHESTRA framework. We make use of our prototype ORCHESTRA implementation and our experience gained with a previous demo setup [6,9]. Instead of using a static setup, we use a mobile robot in a restricted area that can be remotely controlled.…”

Today's electronic devices have multiple communication technologies available at any time. Currently, the application layer or the user needs to manually switch between them, depending on the networks in range. No holistic and adaptive approach exists that can manage all technologies and devices at once. To this extent, we previously proposed the inter-technology management framework ORCHESTRA. The framework is the first of its kind in providing fine-grained packet-level control across different network technologies in a network-wide manner. In this paper, we present a real-life implementation of this framework and show that it can cope well with mobility requirements of users by offering seamless inter-technology handovers.

Abstract-Local area networks (LANs) are employed by a plethora of heterogeneous consumer devices, equipped with the ability to connect to the Internet using a variety of different wireless network technologies. Existing solutions and the lower layers of the OSI stack are unfit to cope with this heterogeneity. For instance, dynamical inter-technology switching is user-of application-based. We propose the ORCHESTRA framework to manage the different devices in heterogeneous wireless local area networks (WLANs) and introduce capabilities such as packetlevel dynamic and intelligent handovers (both inter-and intratechnology), load balancing, replication, and scheduling. The framework consists of a controller that is capable of communicating with both existing Software-Defined Networking (SDN) and Network Function Virtualization (NFV) controllers and with devices containing a newly introduced virtual Medium Access Control (MAC) layer. We show that the virtual MAC enables transparent and real-time inter-technology handovers and that our solution scales up to two thousands of clients.
