E-GENI

From OpenFlow Wiki

Enterprise-GENI represents the control software stack that enables network programmability. As shown in the figure, it is composed of four main entities:

• OpenFlow-based Substrate: The switches that communicate using the OpenFlow protocol to a controller application
• FlowVisor: A custom-build OpenFlow controller that isolates control traffic of individual experiments.
• OptIn Manager: The application used by the network administrator to allow experiments to be hosted in an OpenFlow-based network. It interacts with the FlowVisor to push needed slice definitions.
• Expedient: The experimenters' portal for creating experiments and describing the required resources. It features a web-based GUI as its interface to the experimenter.

A centralized Expedient may be used to manage several aggregates (substrates), using either the GENI API with the individual Expedient instances or directly to the individual Opt-in Managers. This provides experimenters with a global view.
