Abstract
GENI is a federated infrastructure that provides GENI experimenters with access to multiple different testbeds, enabling networking and distributed systems research. Although GENI resources are owned and operated by different organizations from a users perspective GENI appears as a unified virtual laboratory. An experimenter can instantiate custom Layer 2 topologies that include a variety of compute and network elements. This ability is achieved through the use of tools, as well as common APIs and shared authentication and authorization procedures across the federation.

Notes
- 1.
Through common APIs and policy agreements, GENI users can actually access resources from around the globe.
- 2.
Network slicing is done by VLAN with the appropriate bandwidth limits and there is no over-provisioning of network capacity. Some resource providers may over-provision compute resources by allocating more virtual machines on a server than available cores or memory. GENI also provides a limited number of bare metal machines that users can reserve in their experiments.
- 3.
GENI’s architecture supports multiple Slice Authorities. For example GENI currently has three Slice Authorities that can register slices used in the federation: The GENI Slice Authority operated by the GPO and the PlanetLab and Emulab Slice Authorities.
