| | 18 | == Step 1. Obtain resources == |
| | 19 | |
| | 20 | This tutorial can use compute resources from InstaGENI racks that support stitching. For a list of available InstaGENI racks that support stitching see the [wiki:GeniNetworkStitchingSites] page. The experiment will need: |
| | 21 | * 1 Xen VM with a public IP to be an OpenFlow controller |
| | 22 | * 1 Xen VM to be the !OpenFlow switch |
| | 23 | * 3 Xen VMs as hosts |
| | 24 | |
| | 25 | [[Image(GENIExperimenter/Graphics:OVSOpenFlowTutorialTopology.jpg,40%)]] |
| | 26 | |
| | 27 | |
| | 28 | If you are attending a Tutorial, the resources might have been reserved for you, check with your instructor and skip this step. |
| | 29 | You can use any reservation tool you want to reserve this topology. We will need two slices for this tutorial: |
| | 30 | * A slice with a single VM that runs your !OpenFlow controller |
| | 31 | * An slice the reserves your compute resources including a VM with OVS installed. |
| | 32 | |
| | 33 | To reserve resources use your favorite resource reservation tool (Omni, Portal, jFed): |
| | 34 | 1. In your slice that will run the !OpenFlow controller: Reserve a VM running the controller using the request RSpec [http://www.gpolab.bbn.com/exp/OpenFlowOVS/pox-controller.rspec]. This RSpec is available at the Portal and is called "XEN VM POX Ctrl" |
| | 35 | 2. In the slice that will run your hosts do the following to reserve your topology: |
| | 36 | i. In Jacks, load this rspec [http://www.gpolab.bbn.com/experiment-support/OpenFlowOVS/openflowovs-all-xen.rspec.xml]. This RSpec is available at the Portal and is called "OpenFlow OVS all XEN" |
| | 37 | ii. Add a new site |
| | 38 | iii. Drag one of your hosts (NOT THE OVS SWITCH) to the new site |
| | 39 | iv. Assign a specific aggregate to each site |
| | 40 | v. Hit reserve |
| | 41 | |
| | 42 | === iMinds Testbed === |
| | 43 | The topology for the iMinds testbed is very similar but it uses |
| | 44 | * 1 raw PC as an OVS switch |
| | 45 | * 3 raw PCs as hosts |
| | 46 | |
| | 47 | You can use any reservation tool you want to reserve this on iwall2 using this rspec: |
| | 48 | http://www.gpolab.bbn.com/exp/OpenFlowOVS/openflowovs-pcs-iwall2.rspec |
