Tsumiki: A Meta-Platform for Building Your Own Testbed
Bibliographic record
Abstract
Network testbeds are essential research tools that have been responsible for valuable network measurements and major advances in distributed systems research. However, no single testbed can satisfy the requirements of every research project, prompting continual efforts to develop new testbeds. The common practice is to re-implement functionality anew for each testbed. This work introduces a set of ready-to-use software components and interfaces called Tsumiki to help researchers to rapidly prototype custom networked testbeds without substantial effort. We derive Tsumiki's design using a set of component and interface design principles, and demonstrate that Tsumiki can be used to implement new, diverse, and useful testbeds. We detail a few such testbeds: a testbed composed of Android devices, a testbed that uses Docker for sandboxing, and a testbed that shares computation and storage resources among Facebook friends. A user study demonstrated that students with no prior experience with networked testbeds were able to use Tsumiki to create a testbed with new functionality and run an experiment on this testbed in under an hour. Furthermore, Tsumiki has been used in production in multiple testbeds, resulting in installations on tens of thousands of devices and use by thousands of researchers.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
