Due to a ransomware attack, the wiki was reverted to a July 2022 version. . We apologize for the lack of a more recent valid backup.

The application has three different modes for three different type of paths:
- shortest were : highlights the shortest paths between the source and the destination are highlighteddisjoint were the
- disjoint: highlights the disjoint paths between the source and the destination are highlighted
- geoPath where the highlights the geographically shortest path is highlighted.
Application Key bindings
While in the PathPainter application there are different key mappings and buttons for different functionalities.
| Button | Key | Functionality |
|---|---|---|
 | [ | Set source device |
 | ] | Set destination device |
 | 3 | Swap source and destination device |
 | 4 | Set the path computation to shortest |
 | 5 | Set the path computation to disjoint |
 | 6 | Set the path computation to geoData |
 | Right arrow | Go to the next path in the set of paths from source and destination |
 | Left arrow | Go to the previous path in the set of paths from source and destination |
Usage
In order to use the PathPainter application you need to have onos installed and configured. In the ONOS console you should first
First step is to start the gui:
| Code Block |
|---|
$: onos-gui gui |
Once the GUI is stated up in your browser you should activate the pathpainter app by opening the left-side panel, going to applications, findin finding org.onosproject.pathpainter and cliking clicking the activate button on the upper-right side corner.
You can than then return to the topology view and open the toolbar panel in the bottom left side of the screen by pressing the dot key.
Once you have the toolbar open you should see the pathPainter Icon:
(todo insert top icon). Clicking on the Icon will activate the application GUI overlay. While in the PathPainter application there are different key mappings and buttons for different functionalities.

Once you have the overlay active you can select an element and set it, through the button or the 1 key, as the source from which you want to see the paths. The selected element should now have a "Src" badge. Afterwards you should select another host and set it as the the destination. A "Dst" badge will appear and you will see some highlighted paths. If you have not changed previously the mode it will be shortest by default.
The paths will be highlited in two colors, yellow for the current primary path and green for all the others paths between the two elements. Now you can circle between the paths with the correct buttons or the keyboard arrows.
When you select a different mode you can see that the highlighted paths change, in this case we selected disjoint paths mode.
