    55This page illustrates an !OpenFlow (OF) example for the [wiki:HowToUseOmni Omni How-to] page. OpenFlow is used for the control of the network resources in the GENI backbone and at Meso-scale campus locations.  Experimenters can use GENI resources without learning !OpenFlow. Experimenters can choose to control the network switching fabric in their slices by running an !OpenFlow controller. Many experimenters use existing !OpenFlow controller code as-is, some use controllers with relatively simple modifications, and some experimenters have written their own controller.  The GPO is available to help design your controller and plan your experiment configuration.  Feel free to contact us at [mailto:help@geni.net].

    7 The experiment in this page uses Omni from the gcf 1.6.1 package to reserve resources.  If you are using gcf 2.0 or higher, note that you '''must''' specify the AM API version option ''' ''-V 1'' ''' for all Omni commands that are executed at !OpenFlow and MyPLC aggregates, these aggregates support AM API V1. The example in this page uses credentials from the GPO ProtoGENI Clearinghouse (pgeni.gpolab.bbn.com) to set up a 3 Meso-scale sites !OpenFlow experiment. The sites are  BBN, Wisconsin and Clemson each with a MyPLC compute resource. If you are interested in using PG resources, see the [http://groups.geni.net/geni/wiki/HelloGENI HelloGENI] experiment page for an !OpenFlow experiment using PG nodes.

If you are using gcf 1.X you do not need to specify ''' ''-V 1'' ''', as the AM API version 1.0 is the default for gcf 1.x packages.

    712712Remember, to renew the slice and slivers reservation time, as the default time is 8 hours. You may find out the current expiration time by using Omni sliverstatus commands. Following are the commands to determine the current sliverstatus along with the expiration times at each aggregate:
