Key GENI Concepts

This page introduces GENI concepts and terms you will need to know before you use GENI. For a glossary of GENI terms, see


A project organizes research in GENI, containing both people and their experiments. A project is led by a single responsible individual: the project lead. A project may have many experimenters as its members. An experimenter may be a member of multiple projects. The project lead is is ultimately accountable for all actions by project members in the context of the project.

The following figure illustrates a situation where a professor is a lead for two GENI projects Alpha and Beta. Each project has a research assistant as one of its members. The professors and his post-doc are members of both projects.

GENI is a shared testbed i.e. multiple experimenters may be running multiple experiments at the same time. This is possible because of the concept of a 'slice' in GENI. A slice consists of reserved resources and the set of GENI experimenters entitled to act on those resources.

  • Experiments live within slices i.e. they use resources reserved by their slice.
  • Slices isolate experiments. GENI is a shared testbed and slices ensure experimenters do not interfere with one another.
  • Experimenters are responsible for their slice and will be held accountable for any adverse behaviors by experiments in their slices.
