-# Axel: Introduce scenario: CNs, nodes, admins.

-- A testbed consists of a set of nodes managed by the same server. *##*
+Here you see two CNs with several nodes connected to them, all managed by
+their respective admins.

+- A testbed consists of a set of nodes managed by the same server.
   - Server managed by testbed admins.
   - Network and nodes managed by CN members.
   - Node admins must adhere to testbed terms and conditions.
-  - This decouples testbed management from infrastructure ownership & mgmt. *##*
+  - This decouples testbed management from infrastructure ownership & mgmt.
 - Testbed management traffic uses a tinc mesh VPN:
   - Avoids problems with firewalls and private networks in nodes.
   - Uses IPv6 to avoid address scarcity and incompatibility between CNs.
-  - Mgmt connections are short-lived to tolerate link instability. *##*
+  - Mgmt connections are short-lived to tolerate link instability.
 - Gateways are entry points to the mgmt network.
   - They help extend it over multiple CNs by external means (e.g. FEDERICA, the
     Internet).
-  - They can also route the management network to the Internet. *##*
+  - They can also route the management network to the Internet.
 - Researchers run experiments in slices spread over several nodes (as
   slivers). *##*
 
 ** Slices, slivers and nodes
 # Axel: Reverse, from PoV of researcher: select nodes, run as slivers, gruop in slices.
