  stations, etc. to be used by the community. *##*
- In a more sophisticated approach, nodes can also be used to implement cloud
  infrastructure provided and managed by the community for the community.
  This is the mission of the Clommunity project. *##*

* Architecture and technologies
** Testbed architecture

- Community-Lab consists of a set of nodes (managed by CN members) that follow
  the configuration in a set of servers (managed by testbed operators).
- All components in the testbed become reachable via a dedicated management
  network implemented as an IPv6 overlay.
- Researchers define experiments (so called slices) in a server.
- Nodes use a REST API to get those definitions from servers and run several
  of them simultaneously as VMs (so called slivers).
- Slivers can access the CN via NAT, natively at the network layer, or in an
  isolated VLAN for routing experiments. *##*

** Technologies

- Nodes are connected via Ethernet to normal community devices.
- Nodes are moderately powerful computers running OpenWrt with a control
  daemon written in Lua.  Slivers are implemented as Linux containers.  We are
  working on safe node upgrade using kexec.

- The GUI and REST API in servers are implemented as Django applications.
- The IPv6 overlay used for the management network is a tinc mesh VPN.
- We use Git, Redmine, Jenkins and our Virtual CONFINE Tesbed (VCT) package
  for development and testing. *##*

* Collaborations
- CONFINE actively collaborates to the development of several Free software
  projects: the OpenWrt router distro, the BMX6 and OLSR mesh routing
  protocols, the DLEP protocol for collecting link characteristics, the NodeDB

  This is the mission of the Clommunity project. *##*

* Architecture and technologies
** Testbed architecture
- How does the Community-Lab testbed work?
- It consists of a set of nodes (managed by CN members) that follow the
  configuration in a set of servers (managed by testbed operators).
- All components in the testbed become reachable via a dedicated management
  network implemented as an IPv6 overlay.
- Then researchers define experiments (the so called slices) in a server.
- And nodes use a REST API to get those definitions from servers and run
  several of them simultaneously as VMs (the so called slivers).
- Slivers can access the CN via NAT, natively at the network layer, or in an
  isolated VLAN for routing experiments. *##*

** Technologies
- Nodes are moderately powerful computers (like this barebone computer)
  connected via Ethernet to normal community devices (i.e. routers). *##*

- Nodes run OpenWrt with a control daemon written in Lua.  Slivers are
  implemented as light Linux containers.  We are working on safe node upgrade
  using kexec. *##*
- The GUI and REST API in servers are implemented as Django applications.
- The IPv6 overlay used for the management network is a tinc mesh VPN. *##*
- We use Git, Redmine, Jenkins and our Virtual CONFINE Tesbed (VCT) package
  for development and testing. *##*

* Collaborations
- CONFINE actively collaborates to the development of several Free software
  projects: the OpenWrt router distro, the BMX6 and OLSR mesh routing
