= Module C Design and Setup = == 1. Obtain resources == This experiment is an extension of the experiment described in [wiki:GEC20Agenda/LabWiki/ModuleA Module A] We use this experiment to demonstrate how an existing project can be easily scaled up. For this experiment we will need: * 6 VMs (NodesA-F) with images that come with pre-installed GIMI tools. For more details on what is installed on these images go [http://groups.geni.net/geni/wiki/GIMIv3/Documentation#Images here] (Type A) * 2 VMs (Switch1 and Switch2) with images that come with pre-installed GIMI tools and OVS. (Type B) The Type A nodes represent regular end systems while the Type B nodes are used as a software-based OpenFlow (OVS) switch. The resulting slice topology for this experiment is shown in the screenshot below. [[Image(flack-extended-topo.png, 70%)]] You can use any reservation tool you want to reserve this topology: * For Omni or Flack you can use the [wiki:GENIExperimenter/RSpecs RSpec] that is published at: http://emmy9.casa.umass.edu/GEC-20/gec20learningswitchextended-eg.rspec for ExoGENI and http://emmy9.casa.umass.edu/GEC-20/gec20learningswitchextended-ig.rspec for InstaGENI * At the [https://portal.geni.net GENI Portal] there is a public RSpec called "'''EG-learning-switch-extended'''" that you can use for ExoGENI resources and "'''IG-learning-switch-extended'''" for InstaGENI resources. Look at the [wiki:GEC20Agenda/LabWiki#Prerequisites Prerequisites] for Tutorials about reserving resources. === 1.1 Login to Nodes sender and Receiver === ==== 1.1.1 Find your Aggregate ==== Click on your Slice name in the GENI Portal and scroll to the aggregate where you reserved your resources.
