An Introduction to GENI and Your 1 st Experiment using GENI Violet R. Syrotiuk Arizona State University Based on a presentation by Sarah Edwards and Vic Thomas, GENI Project Office Sponsored by the National Science Foundation
Outline • What is GENI? • How is GENI being used? • An experimenter’s view of GENI • Two hands-on exercises 1. Create a simple topology and experiment with it 2. A routing exercise using an existing topology Sponsored by the National Science Foundation GENI Regional Workshop (GRW) at The University of Oregon – November 3, 2017 3
Why GENI? Science Issues We cannot currently Innovation Issues understand or predict the Substantial barriers to behavior of complex, at-scale experimentation with large-scale networks new architectures, services, and technologies Society Issues We increasingly rely on Credit: MONET Group at UIUC the Internet but are unsure we can trust its security, privacy or resilience These issues are becoming increasingly important with ubiquitous connectivity, IoT, cybercrime.

Mars Rover Game Students at a high school in Colorado learn math and programming using the Mars Rover game The Mars Rover has crash landed and the student must help the rover repair itself, build shelter, and prepare for colonists before they arrive. The game is designed to engage high school students, effectively teach and assess their critical thinking, math, and programming skills. - https://www.adlnet.gov/mars-game Sponsored by the National Science Foundation GENI Regional Workshop (GRW) at The University of Oregon – November 3, 2017 13

GENI as a Remote Lab Over 4500 students have used GENI in Jennie Albrecht teaches a distributed systems class at classes taught by 73 Williams College, MA instructors Last semester 638 students in 24 classes did labs on GENI Students using GENI in a wireless networking class in Greece Sponsored by the National Science Foundation GENI Regional Workshop (GRW) at The University of Oregon – November 3, 2017 15
Why use GENI for Education? • No need to acquire and maintain expensive lab facilities – 24x7 access from almost anywhere • Enables new lab exercises – Exercises based on expensive and uncommon resources • 4G wireless base stations, long haul network links, programmable switches • Promotes exploratory learning Wide area experiment on GENI – If student messes up a resource configuration, delete and start over • No instructor or administrator intervention needed • Shared community resource – Community developed course modules – Community supported mailing lists One of many wireless resources available for GENI labs Sponsored by the National Science Foundation GENI Regional Workshop (GRW) at The University of Oregon – November 3, 2017 16
