Education modules using GENI Gives students hands-on experience with basic networking principles and protocols Target is Undergraduate Networking courses Ready for use in Fall 2014 courses Novice users! Simple tasks! geni.web.unc.edu

geni.web.unc.edu

Tmix Realistic Traffic Generation Input: anonymized TCP packet header trace Output: synthetic traffic in GENI that is statistically equivalent to the measured traffic http://groups.geni.net/geni/wiki/GeniTmix

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.

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.

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?
