Integrating a next-generation optical access network testbed into a large-scale virtual research testbed

Several experimental research networks have been created in the laboratories of prominent universities and research centres to assess new optical communication technologies. A greater value and research impact can be obtained from these testbeds by making them available to other researchers through research infrastructure federations such as GENI and/or FIRE. This is a challenging task due to the limitations of programmability of resource management and virtualisation software in most experimental optical networks. Fed4FIRE is an EU research project that makes it possible to create complex testbed scenarios that interconnect heterogeneous testbeds distributed physically all over the world. In this paper, we present a practical approach for the federation of a next-generation optical access testbed created at Stanford University called UltraFlow Access. That testbed offers its users both packet-switched and circuit-switched services while remaining compatible with conventional PONs. Our approach facilitates experimentation on the UltraFlow Access testbed in the context of large virtual testbeds using Fed4FIRE protocols.The research of this paper was partially financed by the European Union’s FP7 grant agreement no. 318389 Fed4FIRE Project, the National Science Foundation (grant no. 111174), NSERC, the Spanish projects CRAMnet (grant no.

Integrating a smart city testbed into a large-scale heterogeneous federation of future internet experimentation facilities: the SmartSantander approach

For some years already, there has been a plethora of research initiatives throughout the world that have deployed diverse experimentation facilities for Future Internet technologies research and development. While access to these testbeds has been sometimes restricted to the specific research community supporting them, opening them to different communities can not only help those infrastructures to achieve a wider impact, but also to better identify new possibilities based on novel considerations brought by those external users. On top of the individual testbeds, supporting experiments that employs several of them in a combined and seamless fashion has been one of the main objectives of different transcontinental research initiatives, such as FIRE in Europe or GENI in United States. In particular, Fed4FIRE project and its continuation, Fed4FIRE+, have emerged as "best-in-town" projects to federate heterogeneous experimentation platforms. This paper presents the most relevant aspects of the integration of a large scale testbed on the IoT domain within the Fed4FIRE+ federation. It revolves around the adaptation carried out on the SmartSantander smart city testbed. Additionally, the paper offers an overview of the different federation models that Fed4FIRE+ proposes to testbed owners in order to provide a complete view of the involved technologies. The paper is also presenting a survey of how several specific research platforms from different experimentation domains have fulfilled the federation task following Fed4FIRE+ concepts.This work was partially funded by the European project Federation for FIRE Plus (Fed4FIRE+) from the European Union’s Horizon 2020 Programme with the Grant Agreement No. 732638 and by the Spanish Government (MINECO) by means of the projects ADVICE: Dynamic provisioning of connectivity in high density 5G wireless scenarios (TEC2015-71329-C2-1-R) and Future Internet Enabled Resilient Cities (FIERCE)
