It is a revolution in network based systems. NSF is the immediate funding for community prototyping and experiments. Through this system researchers will be able to build their own new versions of the "net" or to study the "net" in ways that are probably impossible in the present day. It is also important to note that compatibility, with the Internet is not necessary. The principle of GENI is to give researchers the opportunity to experiment freely by assumptions or requirements and to support those experiments at a large scale with real user populations (gpogeni.net n. pag 2007).
The GENI concept is being explored by the US computing community with support from the National Science Foundation. The GENI will aid in networking and distributed systems, and to speed up the application of research into products and services that will in turn enhance the economic competitiveness and secure the Nation's future. It is expected that research performed on GENI will lead to capabilities beyond the Internet as we know it today. Or in other words it can be said that it will be the future of post internet. In fact GENI planning efforts are presently organized around multidusiblinary area, basically linked with architecture, the backbone network, distributed services, wireless/mobile/sensor subnetworks, and research coordination amongst these (Wikipedia n. pag 2007).
In recent decades, the focus of interest in computer science and computing systems has shifted to very large distributed systems. This is mainly because of the realization that this area has much stored income potential and can generate various opportunities. For instance, these systems may include web services, Grid services, content distribution systems, overlay multicast trees, wide area storage systems, and distributed hash tables. These society-scale systems provide exceptional challenges and opportunities for the present world, and rise fascinating new research questions.
Network systems are primarily communication systems, and therefore their emergent behaviors often emerge in human interactions. The scale of a network system where behaviors emerge is not only a scale in terms of number of nodes, but also a scale in terms of number of people utilizing the system. To take a simple example, spam is a phenomenon that only emerges when a large number of people use a networked system. In the same way, peer-to-peer file transfer or an online classified system such as eBay or any other online networking systems only demonstrate interesting properties when a large number of users become attached to the system. In order to study large-scale systems with large numbers of users, an experimental field station where long-running services can be deployed and used by real-world users is required. This is the sole reason for the emergence of GENI.
GENI is intended to play three principal roles for the networking and distributed systems research community in the United States, as a laboratory, as an observatory and as a field experiential station. GENI as a lab is a facility for controlled, repeatable, reproducible experiments under safe conditions which should provide specific, precise, guaranteed conditions for the conduct of experiments, and mutual protective guarantees for facility users and third parties.
