Comment:

Component definition was too processor centric, added optical links to make it better.

    88  A ''clearinghouse'' is a, mostly operational, grouping of a) architectural elements including trust anchors for Management Authorities and Slice Authorities and b) services including user, slice and component registries, a portal for resource discovery, a portal for managing GENI-wide policies, and services needed for operations and management.  They are grouped together because it is expected that the GENI project will need to provide this set of capabilities to bootstrap the facility and, in general, are not exclusive of other instances of similar functions. There will be multiple clearinghouses which will federate. The GENI project will operate the NSF-sponsored clearinghouse. One application of ‘federation’ is as the interface between clearinghouses.

    10  Components::
    11   ''Components'' are the primary building block of the architecture. For example, a component might correspond to an edge computer, a customizable router, or a programmable access point.  A component encapsulates a collection of resources, including physical resources (e.g., CPU, memory, disk, bandwidth) logical resources (e.g., file descriptors, port numbers), and synthetic resources (e.g., packet forwarding fast paths). These resources can be contained in a single physical device or distributed across a set of devices, depending on the nature of the component.  Each component runs a component manager that implements a well-defined interface for the component.  In addition to describing physical devices, components may be defined that represent logical devices as well.
