Why GENI? Science Issues We cannot currently understand or predict the behavior of complex, large-scale networks Innovation Issues Substantial barriers to at-scale experimentation with new architectures, services, and technologies Society Issues We increasingly rely on the Internet but are unsure we can trust its security, privacy or resilience Credit: MONET Group at UIUC These issues are becoming increasingly important with ubiquitous connectivity, Io.

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 Introduction www. geni. net 13

GENI as a Remote Lab Over 4500 students have used GENI in classes taught by 73 instructors Jennie Albrecht teaches a distributed systems class at Williams College, MA Last semester 638 students in 24 classes did labs on GENI Sponsored by the National Science Foundation Students using GENI in a wireless networking class in Greece GENI Introduction www. geni. net 15

Why use GENI for Education? • No need to acquire and maintain expensive lab facilities – 24 x 7 access from almost anywhere • Enables new lab exercises – Exercises based on expensive and uncommon resources • 4 G wireless base stations, long haul network links, programmable switches Wide area experiment on GENI • Promotes exploratory learning – 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 Sponsored by the National Science Foundation GENI Introduction One of many wireless resources available for GENI labs www. geni. net 16

GENI: Terms and Definitions Slice Abstraction for a collection of resources capable of running experiments – An experiment uses resources in a slice – Slices isolate experiments – Experimenters are responsible for their slices Sponsored by the National Science Foundation GENI Introduction www. geni. net 21

Clearinghouse and Aggregates Create & Register Slice credentials user s project s slice s clearinghouse Aggregate Manager API Researcher Tool - list. Resources - create. Sliver … Aggregate Manager Aggregate Resources • Clearinghouse: Manages users, projects and slices – Standard credentials shared via custom API or new Common CH API – GENI supported accounts: GENI Portal/CH, Planet. Lab CH, Proto. GENI CH • Aggregate: Provides resources to GENI experimenters – Typically owned and managed by an organization – Speaks the GENI AM API – Examples: Planet. Lab, Emulab, GENI Racks on various campuses Sponsored by the National Science Foundation GENI Introduction www. geni. net 22
