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 https://panther.gpolab.bbn.com/secure/glossary.html.
Project
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 the lead for two GENI projects Alpha and Beta. Each project has one of the professor's research assistant as a member. The professors and his post-doc are members of both projects.
Slice
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. A slice belongs to a single project, and can have multiple members. A project can have multiple slices.
- 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.
