The n2n architecture is based on two components:Įdge nodes: applications installed on user PCs that allow the n2n network to be build. n2n networks are not meant to be self-contained: it is possible to route traffic across n2n and non-n2n networks.Firewalls no longer are an obstacle to direct communications at IP level.

from outside to inside) so that n2n nodes are reachable even if running on a private network.

Ability to cross NAT and firewalls in the reverse traffic direction (i.e.

Each n2n user can simultaneously belong to multiple networks (a.k.a.

Encryption is performed on edge nodes using open protocols with user-defined encryption keys: you control your security without delegating it to companies as it happens with Skype or Hamachi.

An n2n is an encrypted layer two private network based on a P2P protocol.

used to implement the https protocol) to network protocol, n2n moves P2P from application to network level.

In a nutshell, as OpenVPN moved SSL from application (e.g. two PCs belonging to the same n2n network can ping each other) and be reachable with the same network IP address regardless of the network where they currently belong. This means that users can gain native IP visibility (e.g. N2n is a layer-two peer-to-peer virtual private network (VPN) which allows users to exploit features typical of P2P applications at network instead of application level.
