* Introduction
Hello, I'm (Speaker) from (organization), I work at the CONFINE project and
I'm going to talk you about Community-Lab, a community networking testbed for
the future Internet. *##*
** Community networks
- Infrastructure deployed by organized groups of people for self-provision of
broadband networking that works and grows according to their own interests.
- Like some Free software projects: based on open participation, open and
transparent management, distributed ownership (a big step beyond private and
state-owned infrastructures).
- These also translate into open, free (as in freedom) and neutral networks,
values akin to the Free software movement. Some have mutual agreement texts
similar to Free software liceses.
- The EU in its Digital Agenda regards CNs as fundamental for the
universalization of broadband networking. *##*
** The CONFINE project
- EU-financed project with several partners: CNs, research institutions and
supporting NGOs.
- Mission: support the sustainable growth of CNs by providing the means to
conduct experimentally driven research.
- Supports other projects advancing or extending CNs via financed Open Calls
(now closed).
- Provides a testbed and associated tools and knowledge for researchers to
experiment on real CNs. *##*
** Community-Lab
- CONFINE's testbed: an environment built with real hardware taking part in
real community networks to allow realistic experimental research on network
technologies and services.
- Mostly like PlanetLab: global scale, with experiments sharing resources on a
best effort basis, and as few hardwired management mechanisms as possible.
- Supporting the peculiarities of CNs: distributed ownership, fairness between
users, diversity but also instability.
- All Community-Lab's software and documentation is “free as in freedom” so
you can use it to setup your own CONFINE testbed. *##*
** Community-Lab as community infrastructure
- CONFINE can help physically extend CNs with new Community-Lab nodes.
- Nodes can also host services like web servers, video broadcast
stations, etc.
- Nodes can also be used as infrastructure for cloud infrastructure provided
and managed by the community for the community: 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.
................................................................................
- 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 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
................................................................................
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 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 kind 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.

* Introduction
Hello, I'm (Speaker) from (organization), I work at the CONFINE project and
I'm going to talk you about Community-Lab, a community networking testbed for
the future Internet. *##*
** Community networks
- For those of you who are new to the term, CNs are infrastructure deployed by
organized groups of people for the self-provision of broadband networking
that works and grows according to their own interests.
- Like some Free software projects, they are based on open participation, open
and transparent management, and distributed ownership. This is a big step
beyond private and state-owned infrastructures.
- The previous characteristics translate into open, free (as in freedom) and
neutral networks, values in consonance with the Free software movement.
Some CNs even have mutual agreement texts similar to Free software liceses.
- Atypical as it may seem, the EU in its Digital Agenda regards CNs as
fundamental for the universalization of broadband networking. *##*
** The CONFINE project
- Under the umbrella of the Digital Agenda, CONFINE is a EU-financed project
with several partners: CNs, research institutions and supporting NGOs.
- Its mission is to support the sustainable growth of CNs by providing the
means to conduct experimentally driven research.
- It also supports other projects advancing or extending CNs via financed Open
Calls (which are now closed).
- Last but not least, CONFINE provides a testbed and the associated tools and
knowledge for researchers to experiment on real CNs. *##*
** Community-Lab
- Community-Lab is that testbed: an environment built with real hardware
taking part in actual community networks to allow realistic experimental
research on network technologies and services.
- Mostly like PlanetLab, it is global scale, with experiments sharing
resources on a best effort basis, and having as few hardwired management
mechanisms as possible.
- However, it supports the peculiarities of CNs: their distributed ownership,
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. *##*
** Community-Lab as community infrastructure
- Besids supporting experimentation, CONFINE helps physically extend CNs with
new Community-Lab nodes.
- These nodes can also host services like web servers, video broadcast
stations, etc. for 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.
................................................................................
- 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.

- 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
