    1717= Reserving necessary resources =
    18 Tango GENI has diverse compute resources that are connected over multiple OpenFlow switches. In order to be able to reserve all the needed resources, we should first draw a detailed topology of our experiment. [wiki:TangoGENI Tango GENI] has two backbone VLANs (3715, 3716) each providing a different topology. For this example we are going to use VLAN 3715.
    19 
    20 So using the topology maps of Tango GENI, along with diagrams from [http://groups.geni.net/geni/attachment/wiki/NetworkCore/OF-INT-BB%2025-May-2011.png NLR core], [http://groups.geni.net/geni/wiki/GeniAggregate/GpoLabOpenFlow GPO lab] and
    21 [http://groups.geni.net/geni/wiki/GeniAggregate/ClemsonOpenFlow Clemson lab], we can draw this detailed topology for this simple example :

    4140== Reserve an IP subnet ==
    42 In Tango GENI, if an experiment is a layer 3 experiment, it would need it's own separate IP subnet so that it is able to control all traffic for this subnet without interfering with traffic from other experiments. GPO has set aside 10.42.0.0/16 as a pool of IP subnets for this. These subnets aren't provided by an aggregate, and thus can't be reserved via the GENI AM API. Please DO NOT use an IP subnet that you have not reserved, just request for one to assigned to you.

    6463== Create slivers ==
    65 For each aggregate we would need to create a sliver that will contain the necessary resources. For all aggregates it is important to now the AM url for requesting the resources. The best place to get the information is at [wiki:GeniAggregate the Aggregate's wiki page].  At [wiki:TangoGENI] there is also a list of URLs of active aggregates. If there is an aggregate whose URL you can't find, please email [mailto:help@geni.net].

The best place to get the information is at [wiki:GeniAggregate the Aggregate's wiki page].  Also the example [source:trunk/wikifiles/hello-geni/omni_config] file has a list of all the AMs along with assigned nicknames. If you include a similar section in your omni_config file then you can refer to AMs using their nicknames. If there is an aggregate whose URL you can't find, please email [mailto:help@geni.net].
