= Module A Design and Setup = == 1. Obtain resources == For this experiment we will need: * 4 VMs with images that comes with pre-installed GIMI tools. (Type A) * 1 VM with images that comes with pre-installed GIMI tools and OVS. (Type B) The Type A nodes represent regular end systems while the Type B node is used as a software-based OpenFlow (OVS) switch. The resulting slice topology for this experiment is shown in the screenshot below. [[Image(Toposetup.png, 60%)]] The various parts of the diagram are as follows: - sender. This node will run a layer 2 ping client which we will instrumentize - receiver. This node will run a simple layer 2 ping Server aka !PingPlus 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-19/layer2ping.rspec and any ExoGENI AM * At the [https://portal.geni.net GENI Experimenter Portal] there is a public RSpec called "'''GEC19GIMI'''" that you can use, and either of the ExoGENI AMs Look at the [wiki:GEC19Agenda/GIMI/Procedure#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.
