For a quick Demo: Click on "Demo" and
select one of the protocols. The simulation starts automatically.
- Black nodes are called "physical nodes" and represent
routers or hosts. Black edges represent ("physical") links at the network layer.
- Yellow nodes and edges represent nodes and edges of the
- Note: It is possible to add and remove overlay
nodes or modify the physical network, while the simulation is running.
Controlling a Running Simulation:
- Click on buttons: "Stop",
"Run", "Next Event", "Next Frame",
- Controlling the Display:
- Click on "View" and select/deselect
one of the display option.
- The routing trees in the overlay network are shown by
selecting "Show Routing Trees" and clicking on an overlay node.
- Drawing a Topology:
- Add or Remove Physical Nodes:
Click on "Add/Remove Physical Nodes".
Generate new physical nodes by clicking (with the left mouse button) in
Remove physical nodes, by clicking on a physical nodes in the canvas.
- Add Physical Edges:
Click on "Add Physical Edges".
Generate a new edge by clicking on one physical node and by dragging the mouse to
another physical node.
- Remove Physical Edges:
Click on "Delete Physical Edges".
Click on physical edges in the canvas
- Add or Remove Overlay Nodes:
Click on "Add/Remove Overlay Nodes".
Generate a new overlay node by clicking on a physical node.
Remove an overlay node by clicking on an existing overlay node.
- Show Routing Tree.
Click on an existing overlay node".
- Clear the canvas:
Click on "Clear All".
- Once the topology is drawn, click on
"Protocol" to select an overlay protocol. Then, select "Run" to start the simulation.
- Clicking the right mouse button switches between the
drawing options, e.g., "Add/Remove Physical Nodes", "Add
Physical Edges", and so on.
