Experiment Control using OMF
OMF functions - deploy and configure experiment - initiate and control experiment - measure and collect data
Experiment description - written in Ruby
OMF is used by many different testbeds

Wireless Testbed at NYU Poly
Today we will run our experiments at NYU Poly
Sponsored by the National Science Foundation 8GENI WiMAX Tutorial – 19 September 2015 www.geni.net
Testbed at NYU
12 “Yellow Nodes”
Testbed console - Experimenter logs in to submit
experiment script - Experiment controller uses aggregatemanager to find nodes for experiment - Aggregate manager gives relevantportions of script to node resourcecontrollers - Resource controllers translate script to OS commands
