What’s New With FABRIC?

An update from Ilya Baldin, FABRIC Principal Investigator

The FABRIC team is continuing to build out the testbed footprint. After many vendor logistics-related delays we now have firm dates for the delivery of the remaining Phase 1 sites at Clemson, UCSD, FIU, GPN/UMKC, while completing the orders for Phase 2 site hardware. Release 1.2 of the FABRIC software stack is being readied for production deployment in the upcoming days. This release will include new experimenter features like ‘Facility Ports’ to create experiment slices that include resources external to FABRIC, ‘Mirror Ports’ that allow mirroring traffic from the dataplane into a slice and a number of others. Be sure to check the Release Notessection for detailed updates when they become available. 

We are working with our partners at Open Cloud Testbed (University of Massachusetts and Northeastern University) to create FPGA-based P4 experiment workflows usable on FABRIC, stay tuned for more updates on it this summer. We expect to deploy Tofino-based P4 switches in FABRIC in the fall. 

In lieu of a Spring KNIT workshop, the FABRIC team hosted a KNIT Spring ‘22 Webinar. Additionally, we are continuing to onboard new early experimenters using monthly tutorial webinars, which are now open to the public. You can find more information about accessing materials from these events and attending future iterations below.


Recording from KNIT Spring ‘22 Webinar

April 28, 2022

Thank you again to those who attended the KNIT Winter ’21 Workshop, and helped us make it a success! The FABRIC team enjoyed hearing all the thoughts and feedback based on the sessions and information shared.

The FABRIC testbed leadership team used the hour to provide site installation status updates, share new features on the testbed, and introduce tutorial sessions and videos. Additionally, the team discussed how the platform enables novel approaches to distributed and network systems control and management by integrating artificial intelligence (AI), and how users can utilize the AI capabilities in their proposals, papers, workshops and more.

FABRIC In The News

A Reimagined Internet

When the internet launched in the last century it was an amazing feat of science and technology. But it was not designed for the massive data sets, machine-learning tools, advanced sensors and Internet of Things devices that have become central to many research and business endeavors and our homes.

Funded with a $20 million grant from the National Science FoundationFABRIC (Adaptive Programmable Research Infrastructure for Computer Science and Science Applications) is exploring ways to replace an internet infrastructure that’s been showing its age for the last 20 years.

NCSA is one of 13 collaborating institutions helping create a platform for testing novel internet architectures that could enable a faster, more secure internet better suited for today’s users and future needs. One that’s also able to do things not possible now. The FABRIC project is led by the Network Research and Infrastructure Group at RENCI at the University of North Carolina at Chapel Hill.

FABRIC: A Testbed of Testbeds

Participating Testbeds and Facilities

FABRIC is a testbed of testbeds, helping users experiment using multiple testbeds. Like Lego blocks, users can get accounts on several testbeds and build an experiment using all of them. Additionally, testbeds can be powered by FABRIC. FABRIC can support testbeds as an underlying infrastructure, while not necessarily exposing the FABRIC interfaces to their users. 

The list of participating testbeds and facilities is growing and currently includes  and currently includes over twelve members. Testbeds and facilities can be added to the page using this form.
