the fairness between their users, and their diversity but also
their instability.
- It's important to note that all Community-Lab's software and documentation
is “free as in freedom” so you can use them to setup your own CONFINE
testbed. *##*

- 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). *##*

- 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. *##*
- Finally, 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
for describing CN nodes, the lower-level Wibed testbed, and the quick mesh
project distro.
- CONFINE also collaborates in events like the Wireless Battle Mesh and the
International Summit for Community Wireless Netwroks. *##*
* Future
- In the near future we plan to work further on the testing, stabilization and
documentation of the testbed to make it more maintainable and usable for the
long term.
- We will also start work on federating CONFINE testbeds between themselves
and with PlanetLab-like testbeds using the Slice-based
Federation Architecture.
- We will be gradually opening the Community-Lab testbed to all kinds of
external users in the networking and academic communities. *##*

* Participate!
- So this was a very schematic summary about community networks, the CONFINE
project and its Community-Lab testbed.
- For more information you can visit these links or meet us in person in the
CONFINE stand in the K building.
