40 | 40 | A portal denotes the interface—graphical, programmatic, or both—that defines an “entry point” through which users access GENI. A portal is likely implemented by a combination of services. Different user communities can define portals tailored to the needs of that community, with each portal defining a different model for slice behavior, or support a different experimental modality. For example, one portal might create and schedule slices on behalf of researchers running short-term controlled experiments, while another might acquire resources needed by slices running long-term services. Yet another portal might be tailored for operators that are responsible for keeping GENI components up and running. |
