4. Tmix Realistic Traffic Generation
Input: anonymized TCP packet header trace
Output: synthetic traffic in GENI that is statistically equivalent to the measured traffic

5. What works? Students love real-world hands-on assignments. Tmix
Tmix Calibration tutorial at GEC20 worked very well! All students successfully ran Tmix on GENI.

6. What doesn’t work? Setup takes too long! Need more Consistency
Setup time is more than half the time required for most modules.
Need more Consistency
Some aggregates seem to work better than others
There are too many options for novice users.

7. Suggestions Can anything be done to decrease wait times?
Can we create a barebones image for shorter image/boot times?
Is there any way to speed up instrumentation?
Why must I wait after deleting resources?
Can we have an “I don’t care which aggregate” option?
Load balancing, and giving only resources from aggregates that are currently working well.
or at least have a dynamic list?
