FESTIVAL: heterogeneous testbed federation across Europe and Japan

FESTIVAL is an H2020 EU-Japan collaborative project that aims to federate heterogeneous testbeds, making them interoperable and building an “Experimentation as a Service” (EaaS) model. Going beyond the traditional nature of experimental facilities, related to computational and networking large scale infrastructures, FESTIVAL testbeds have heterogeneous nature and in order to be federated they have been clustered in four categories: “Open Data” (i.e. open datasets), “IoT” (i.e. sensors and actuators), “IT” (i.e. computational resources) and “Living Labs” (i.e. people). Considering that every testbed category provides specific resources, the main challenge for FESTIVAL is to develop a platform that can allow experimenters to access very different assets in an homogeneous and transparent way, supporting them in the phases of the experiments. The FESTIVAL architecture, based on a multi-level federation approach, proposes a solution to this problem providing also a set of functionalities to manage and monitor the experiments. FESTIVAL tools, also, include the possibility to access FIWAREGeneric Enablers allowing to deploy predefined components to address specific needs in the experimentation (e.g. data analysis, big data management etc.). The FESTIVAL platform will be tested on three different smart city domains across Japan and Europe: smart energy, smart building and smart shopping.This work was funded in part by the European Union’s Horizon 2020 Programme of the FESTIVALproject (Federated Interoperable Smart ICT Services Development and Testing Platforms) under grant agreement no. 643275, and by the Japanese National Institute of Information and Communications Technology

FIWARE Lab: managing resources and services in a cloud federation supporting future internet applications

Real-world experimentation facilities accelerate the development of Future Internet technologies and services, advance the market for smart infrastructures, and increase the effectiveness of business processes through the Internet. The federation of facilities fosters the experimentation and innovation with larger and more powerful environment, increases the number and variety of the offered services and brings forth possibilities for new experimentation scenarios. This paper introduces a management solution for cloud federation that automates service provisioning to the largest possible extent, relieves the developers from time-consuming configuration settings, and caters for real-time information of all information related to the whole lifecycle of the provisioned services. This is achieved by proposing solutions to achieve the seamless deployment of services across the federation and ability of services to span across different infrastructures of the federation, as well as monitoring of the resources and data which can be aggregated with a common structure, offered as an open ecosystem for innovation at the developers' disposal. This solution consists of several federation management tools and components that are part of the work on Cloud Federation conducted within XIFI project to build the federation of cloud infrastructures for the Future Internet Lab (FIWARE Lab). We present the design and implementation of the solution-concerned FIWARE Lab management tools and components that are deployed within a federation of 17 cloud infrastructures distributed across Europe

An experimental study on latency-aware and self-adaptive service chaining orchestration in distributed NFV and SDN infrastructures

Network Function Virtualization (NFV) and Software Defined Networking (SDN) changed radically the way 5G networks will be deployed and services will be delivered to vertical applications (i.e., through dynamic chaining of virtualized functions deployed in distributed clouds to best address latency requirements). In this work, we present a service chaining orchestration system, namely LASH-5G, running on top of an experimental set-up that reproduces a typical 5G network deployment with virtualized functions in geographically distributed edge clouds. LASH-5G is built upon a joint integration effort among different orchestration solutions and cloud deployments and aims at providing latency-aware, adaptive and reliable service chaining orchestration across clouds and network resource domains interconnected through SDN. In this paper, we provide details on how this orchestration system has been deployed and it is operated on top of the experimentation infrastructure provided within the Fed4FIRE+ facility and we present performance results assessing the effectiveness of the proposed orchestration approach

5G-MEC Testbeds for V2X Applications

Fifth-generation (5G) mobile networks fulfill the demands of critical applications, such as Ultra-Reliable Low-Latency Communication (URLLC), particularly in the automotive industry. Vehicular communication requires low latency and high computational capabilities at the network’s edge. To meet these requirements, ETSI standardized Multi-access Edge Computing (MEC), which provides cloud computing capabilities and addresses the need for low latency. This paper presents a generalized overview for implementing a 5G-MEC testbed for Vehicle-to-Everything (V2X) applications, as well as the analysis of some important testbeds and state-of-the-art implementations based on their deployment scenario, 5G use cases, and open source accessibility. The complexity of using the testbeds is also discussed, and the challenges researchers may face while replicating and deploying them are highlighted. Finally, the paper summarizes the tools used to build the testbeds and addresses open issues related to implementing the testbeds.publishedVersio

Testbeds Support for Reproducible Research

International audienceIn the context of experimental research, testbeds play an important role inenabling reproducibility of experiments, by providing a set of services thathelp experiments with setting up the experimental environment, and collectingdata about it. This paper explores the status of three different testbeds(Chameleon, CloudLab and Grid'5000) regarding features required for, or relatedto reproducible research, and discusses some open questions on that topic

Building the Future Internet through FIRE

The Internet as we know it today is the result of a continuous activity for improving network communications, end user services, computational processes and also information technology infrastructures. The Internet has become a critical infrastructure for the human-being by offering complex networking services and end-user applications that all together have transformed all aspects, mainly economical, of our lives. Recently, with the advent of new paradigms and the progress in wireless technology, sensor networks and information systems and also the inexorable shift towards everything connected paradigm, first as known as the Internet of Things and lately envisioning into the Internet of Everything, a data-driven society has been created. In a data-driven society, productivity, knowledge, and experience are dependent on increasingly open, dynamic, interdependent and complex Internet services. The challenge for the Internet of the Future design is to build robust enabling technologies, implement and deploy adaptive systems, to create business opportunities considering increasing uncertainties and emergent systemic behaviors where humans and machines seamlessly cooperate
