Community-Lab introduction

#+title: Community-Lab: Exploring the Future Internet on Community Networks

* 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.
- 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 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
  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.

# Community networks (CNs)

- Broadband self-provision
- Similar to Free software:
    - Open participation & management,  
      distributed ownership
      <!--- private / public / community --->
    - Open, Free, neutral networks  
    - Mutual agreement texts
- Key for EU Digital Agenda

# The CONFINE project

- Partners:
    - CNs: guifi.net, Funkfeuer, AWMN
    - Research: UPC, FKIE, iMinds
    - NGOs: Pangea, OPLAN
<!--- logos --->
- Support sustainable growth of CNs via research  
  (technologies & services)
- Help other projects boost CNs (Open Calls)
<!--- OC1 & OC2 project listing --->
- Provide a testbed for CNs: Community-Lab

# Community-Lab

- A testbed built on community networks
- Like PlanetLab:
    - Global scale
    - Experiments sharing resources
    - Best effort
    - Unbundled management
- Heavily customized for CNs:
    - Some decentralization
    - Fair to other users  
      (no spying, no low-level, routing & above)
    - Simple, tolerant to network failures
- Free software: build your own testbed!

# Community-Lab as community infrastructure

- Extend CNs with Community-Lab nodes
