========== re6stnet ========== --------------------------------------------- Resilient, Scalable, IPv6 Network application --------------------------------------------- :Author: Nexedi Overview ======== re6stnet creates a resilient, scalable, ipv6 network on top of an existing ipv4 network, by creating tunnels on the fly, and then routing targeted traffic through these tunnels. re6stnet can be used to: - guarantee connectedness between computers connected to the internet, for which there exists a working route (in case the direct route isn't available). - create large networks - give ipv6 addresses to machines with only ipv4 available HOW IT WORKS ============ A re6stnet network consists of at least one server (re6st-registry) and many nodes (re6stnet). The server is only used to deliver certificates for secure authentification in establishing tunnels, and to bootstrap new nodes. re6stnet can detect and take into account nodes present on the local network. Resilience ---------- re6stnet guarantees that if there exists a route between two machines, traffic will be correctly routed between these two machines. Even if the registry node is down, the probability that the network isn't connected is very low for big enough networks (more than a hundred nodes). Scalability ----------- Since each node has very few data about the network, re6stnet is easily scalable to tens of thousand of nodes Requirements ============ - Python 2.6 or 2.7 - OpenSSL binary and development libraries - OpenVPN - Babel_ - python-miniupnpc for UPnP support (optional) - for the demo: miniupnpd_, Graphviz, Screen, Nemu_ See also `setup.py` for Python dependencies. .. _Babel: http://www.pps.univ-paris-diderot.fr/~jch/software/babel/ _Nemu: http://code.google.com/p/nemu/ _miniupnpd: http://miniupnp.free.fr/ Installation ============ re6stnet is distributed as an Python egg, and is also packaged for Debian. See `re6stnet-registry` to set up a re6st network and `re6stnet-conf` to join an existing network.
