FITS includes tools that help users to easily collect measurements of both physical and virtual network elements.

FITS project provides a simple graphical interface to view its testbed network: http://fits.gta.ufrj.br.

Firstly, to access the interface you must sign on the OpenId identification system  with Smart Card.
Figure 1 shows the main screen of the interface.

Figures 1 and 2 show some available statistics and  accessible virtual routers.

Figure 2: Xen Statistics

Figure 3 shows the FITS network topology. The blue parallelograms represent physical routers with the name and IP address. They can be connected by a tunnel. Attached to them, virtual routers are represented by green cylinders.

In this menu, the operation Migration of virtual routers is available. To do the migration of virtual routers, you must drag a virtual router and drop it on a physical router destination. Wait a few moments and the interface will display the new connection desired.

Figure 4 shows the menu Create a new virtual network. 

Figure 4: Menu Create a new virtual network

To create a virtual network, click on a physical router and automatically will be created  the corresponding virtual routers. Select the virtual router and click the Toggle Link button  to create links between them. For example, with three selected routers and having a link between them, clicking this button twice, the connection is broken and two new connections are created. To commit, click the Create button.

Figure 5 shows the menu Status.  The status is updated hourly to all nodes registered in the interface.
