NICT provides testbed facilities such as JGN, JOSE, RISE, and StarBED to promote research and development of information and communications technology. Recently, a trend to open networking has been accelerating, and many projects have been proposing innovative networking mechanisms utilizing programmable networking capabilities. Especially, data-plane programming with the P4 programing...
A growing number of scientific fields require the ability to analyze data in near real-time, so that results from one experiment can guide selection of the next—or even influence the course of a single experiment. The experiments are often tightly scheduled, with timing driven by factors ranging from the physical processes involved in an experiment to the travel schedules of on-site...
Modern data-centric applications are among the major
drives for next generation Internet and network infrastructure
innovation. These applications, often founded in broad societal
challenges such as overpopulation and diminishing natural
resources, cut across many different scientific domains and
require collection, transfer, and processing capabilities on data
from broad range of...
With the ever growing complexity of networks, researchers have to rely on test-beds to be able to fully assess the quality of their propositions. In the meanwhile, Mininet offers a simple yet powerful API, the goldilocks of network emulators. We advocate that the Mininet API is the right level of abstraction for network experiments. Unfortunately it is designed to be run on a single machine....
Network Function Virtualization (NFV), coupled with Software Defined Networking (SDN),
promises to revolutionize networking by allowing network operators to dynamically modify and
manage networks. Operators can create, update, remove or scale out/in network functions (NFs)
on demand, construct a sequence of NFs to form a so-called service function chain (SFC) and
steer traffic through it...
Unmanned aerial vehicles (UAV) or drone systems equipped with cameras are extensively used in different surveillance scenarios and often require real-time control and high-quality video transmission. However, unstable network situations and various transport protocols may result in impairments during video streaming, which in turn negatively impacts user’s quality of experience (QoE). In this...
Increased ubiquity of sensing via smart devices and IoT devices in smart homes and smart healthcare domains, for example, has caused a surge in sensitive and personal data generation and use from browsing habits to purchasing patterns to real-time location to personal health information. Unfortunately, our ability to collect and process data has overwhelmed our ability to protect that...

This document is a response to the GEFI 2019 call for position statements. This statement includes two major contributions that will be interesting to the GEFI community. First, is an...
With its national and international research partners, the International Center for Advanced Internet Research (iCAIR) at Northwestern University designs, develops, implements, and operates large scale, including world-wide, computer science testbeds. Generally, with its research partners, iCAIR operates between 25 and 30 national, international, and local testbeds. The majority have been...
5G-DIVE targets end-to-end 5G trials aimed at proving the technical merits and business value proposition of 5G technologies in two vertical pilots, namely (i) Industry 4.0 and (ii) Autonomous Drone Scout. Its design is built around two main pillars, namely (1) end-to-end 5G connectivity including 5G New Radio, Crosshaul transport and 5G Core, and (2) distributed edge and fog computing...
In this position paper, CTTC and University of Washington provide a status update regarding new protocol stacks for end-to-end and multi-RAT scenario simulations in the open source network simulator ns-3 (www.nsnam.org). Specifically, the recent advances enable network performance evaluation research in the emergent areas of 5G NR-U and IEEE802.11ax coexistence in unlicensed band. The work...
In this position paper, we focus on the NITOS testbed and the experimentally driven 5G activities around the established experimentation ecosystem it provides. NITOS is a highly heterogeneous testbed located in the premises of University of Thessaly, Greece. The testbed provides remote access to experimenters from around the globe, allowing repeatable experimentation with cutting edge...
Computational science today depends on complex, data-intensive applications operating on datasets from
a variety of scientific instruments. A major challenge is the integration of data into the scientist's workflow.
Recent advances in dynamic, networked cloud resources provide the building blocks to construct
reconfigurable, end-to-end infrastructure that can increase scientific...
Cloud testbeds are critical for enabling research into new cloud technologies - research that
requires experiments which potentially change the operation of the cloud itself. Several such
testbeds have been created in recent past (e.g., Chameleon, CloudLab, etc.) with the goal to
support the CISE systems research community. It has been shown that these testbeds are very
popular and heavily...
Computer Science experimental testbeds allow investigators to explore a broad
range of different state-of-the-art hardware options, assess scalability of their
systems, and provide conditions that allow deep reconfigurability and isolation so
that one user does not impact the experiments of another. Although the primary
purpose of those testbeds is to provide resources to users who would...
Reproducibilification, i.e., making experiments reproducible, is the
ultimate goal for successful scientific experiments. In this work, we
identify key challenges for the design of reproducible network experiments.
We present our approach for reproducible network research
which enforces an experiment workflow leading to inherently replicable
network experiments. Our approach realized in...
