Resilient, Scalable, IPv6 Network application
---------------------------------------------
:Author: Nexedi <re6stnet@erp5.org>
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 very large networks
- give ipv6 addresses to machines with only ipv4 available
HOW IT WORKS
============
A re6stnet networks consists of at least one server ( re6st-registry ) and many
clients or nodes ( re6stnet ). The server delivers certificates for secure
authentification in establishing tunnels, and - for now - store the complete
list of nodes running.
re6stnet detects and take into accounts nodes present on the local network.
Resilience
----------
re6stnet can guarantee that if there exists a route between two machines,
traffic will be correctly routed between these two machines.
Since the destination of established connection are random, there can be no
guarantee that such a route exists given which tunnels are established, but
for big enough networks ( more than a hundred nodes ), the probability that
the network isn't connected is very low.
Scalability
-----------
Since each node has very few data about the network, re6stnet is easily
scalable to tens of thousand of nodes
Requirements
============
- Python 2.7 or later
- OpenSSL binary and development libraries
- OpenVPN
- Babel ( http://www.pps.univ-paris-diderot.fr/~jch/software/babel/ )
