| 1 | As an example experiment, we have set up a [http://geminiportal.uky.emulab.net/path_controller Path Controller] tool. Click on the link or goto http://geminiportal.uky.emulab.net/path_controller . Accept the self-signed certificate. |

| 8 | The tool consist of a web interface that connects to the slice's nodes and allows you to change the routing paths and generate traffic between selected nodes. |

| 11 | The interface has desktop-like windows that can be moved around and resized as you please. The first window we will examine contains the slice's topology. |
| 12 | [[[Image(topo_init_view.png)]] |
| 13 | Each circle represents a node in the network. The lines represent links. Note that the global node (GN) does not have links, it acts in the background. Left click and drag a link to rearrange them. For this tutorial arrange them so they match the geminiportal layout like so: |

| 16 | As you rearrange the nodes, note the window directly below the topology window. This is the information (Info) window. |
| 17 | [[[Image(info_window.png)]] |
| 18 | This window has some brief information about the node or link that the cursor is currently over. This case has information about VM-1. The icon represents a virtual machine. The hostname is pcvm63-2.uky.emulab.net. |

| 20 | This next case is for lan1. The icon represents a link. The ids are displayed for the two end points, along with each interface's ip address. |
