Several representatives from the GENI Project Office will be visiting RENCI on July 7, 2009. As part of the visit Harry Mussman, GENI Senior Systems Engineer will give a talk to the Triangle networking research community titled "GENI: Overview & Plans".


Is there a science for understanding the complexity of our networks so that we can engineer them to have
predictable (or adaptable) behavior?  In response to this fundamental research challenge, the National
Science Foundation (NSF) Directorate for Computer and Information Science and Engineering (CISE),
and the research community, are developing a comprehensive strategy to advance research and
education in Network Science and Engineering.
In parallel, community planning for the suite of infrastructure that will support NetSE experiments has
been underway since 2005. This suite is termed the Global Environment for Network Innovations (GENI).
Although its specific requirements will evolve in response to the evolving NetSE research agenda, the
GENI infrastructure suite is being planned to allow researchers from diverse disciplines across computer
and information science and engineering, as well as from economics and the social sciences, to escape
today's Internet-circumscribed research environment.
The suiteís conceptual design is now clear, and includes the following core concepts:
*    Slice-based Experimentation ñ GENI experiments will run on a ìsliceî, an interconnected set of
reserved resources, or ìsliversî, on heterogeneous substrate platforms and networks. 
Researchers will remotely discover, reserve, configure, and program, debug, operate, manage,
and teardown resources on these platforms and networks to setup, utilize and then teardown the
slivers necessary to complete an experiment.
*    Virtualization ñ Whenever feasible, the substrate platforms and networks will be ìvirtualizedî to
allow multiple researchers to simultaneously share the infrastructure, and operate without
disturbing another experiment, or being disturbed.
*    Programmability ñ When a platform includes a host or other node, researchers will typically be
able to download software into the host or node to control the behavior of the resultant sliver.  In
the case of a network node, this will specialize the function of a node, i.e., provide a custom
routing function or even a software-defined radio transceiver.
*    Federation ñ Different parts of the GENI suite are owned and/or operated by different
organizations, and the NSF portion of the GENI suite forms only a part of the overall

As envisioned in these community plans, GENI will support a wide range of experimental protocols, and
data dissemination techniques running over facilities such as fiber optics with next-generation optical
switches, novel high-speed routers, city-wide experimental urban radio networks, high-end computational
clusters, and sensor grids.  GENI is envisioned to include extensive instrumentation that makes it easy to
collect, analyze, and share measurements.
