Loom with a View (Beta)

This is an experimental, auto-generated dashboard of the dataplane of the FABRIC testbed. Data and graphs for this dashboard are generated using Patchwork, which is invoked every few days across the whole of FABRIC to gather a snapshot of its network activity.
See our paper on Patchwork if you'd like to find out how the whole process works.

See the top-level dashboard that shows historical data.


Beta release: Please send feedback and data/visualization requests to Nik Sultana. You're also welcome to get in touch to contribute code or other improvements. All the code that generated this data (and this page) is open source.

The data that was used to generate this page was gathered on 19 Sep 2025.

Follow-up Note

(Follow-up Notes are manually added to the dashboard to explain some aspect of this Patchwork run that stood out to us.)
On this day we noticed that all instances ended in an "inprogress" state. This happened because a long-lived authentication token used by Patchwork expired, which left Patchwork unable to complete the data gathering. We're looking into how to renew this proactively in the future.

On that day, Patchwork ran continuously for a 12-hour window, during which time:


Distribution of frame sizes in FABRIC's dataplane: This graph shows a histogram of frame sizes. This distribution can hint at the type of workloads that were crossing the network at the time the sample was collected.


Frequently-occurring protocol headers on FABRIC: This graph shows a histogram of the most frequently-occurring protocols that were found in the analyzed sample. This graph complements the previous graph by telling us more about the workloads that were crossing the network at the time the sample was collected.


Variety of application/protocol headers across FABRIC site ports: (anonymised) For different (physical) network ports that are sampled (across different FABRIC sites), this graph shows the variety of different protocols/applications that were observed during the time the sample was collected.
