    47     47   - It's important to note that all Community-Lab's software and documentation
    48     48     is “free as in freedom” so you can use them to setup your own CONFINE
    49     49     testbed. *##*

    55     55     stations, etc. to be used by the community. *##*
    56     56   - In a more sophisticated approach, nodes can also be used to implement cloud
    57     57     infrastructure provided and managed by the community for the community.

           62  +- Now, how does the Community-Lab testbed work? *##*
    63     63   - It consists of a set of nodes (managed by CN members) that follow the
    64     64     configuration in a set of servers (managed by testbed operators).
    65     65   - All components in the testbed become reachable via a dedicated management
    66     66     network implemented as an IPv6 overlay.
    67     67   - Then researchers define experiments (the so called slices) in a server.
    68     68   - And nodes use a REST API to get those definitions from servers and run
    69     69     several of them simultaneously as VMs (the so called slivers).
