Cloud Computing Testbed Chameleon Launches Third Phase with Focus on IoT and Reproducibility The third phase will add expanded tools for reproducible research, allowing easier publication and sharing experimental results so other scientists can replicate and build on it. Because integration with Jupyter notebooks proved popular with the Chameleon community, the team is developing a sharing portal integrated with Zenodo, where experiments can be easily published and discovered. Also, this phase will provide new options for programmable networking including software-defined networking (SDN), including compatibility with networking testbed projects, such as the NSF FABRIC, and new hardware and storage resources at the project’s primary two sites, UChicago, and the Texas Advanced Computing Center (TACC), and at a supplemental site at the International Center for Advanced Internet Research, co-located with the StarLight International/National Communications Exchange Facility in Chicago, which allows for large scale testbed federation and collaboration, including for data intensive science at global scale. That site supports specialized research capabilities including the P4 programming language, large flow appliances, 100 Gbps services, high performance Data Transfer Nodes (DTNs), and testbed integration, including with FABRIC.
The Global StarLight Software Defined Networking Exchange (SDX): A Novel Advanced International Communications Facility A five-year grant to develop an international Software Defined Networking Exchange (SDX) at the StarLight International/National Communications Exchange Facility was announced this week at the Global Lambda Integrated Facility (GLIF) Technical Working Group biannual meeting in Washington DC, co-located with the Open Grid Forum, the Global Environment for Network Innovations (GENI) Engineering Conference (GEC 22), and the US Ignite Applications Summit – “Beyond Today’s Internet: Experiencing a Smart Future.” A consortium of universities received funding to design, develop, and operate the StarLight SDX from the National Science Foundation (NSF) International Research Network Connections (IRNC) program.
