1 n2n is a layer-two peer-to-peer virtual private network (VPN)
2 which allows users to exploit features typical of P2P
3 applications at network instead of application level.
4 This means that users can gain native IP visibility (e.g. two
5 PCs belonging to the same n2n network can ping each other)
6 and be reachable with the same network IP address regardless
7 of the network where they currently belong.
8 In a nutshell, as OpenVPN moved SSL from application (e.g. used
9 to implement the https protocol) to network protocol, n2n moves
10 P2P from application to network level.
12 The main n2n design features are:
14 - An n2n is an encrypted layer two private network based on a
15 P2P protocol.
16 - Encryption is performed on edge nodes using open protocols
17 with user-defined encryption keys: you control your security
18 without delegating it to companies as it happens with Skype
19 or Hamachi.
20 - Each n2n user can simultaneously belong to multiple networks
21 (a.k.a. communities).
22 - Ability to cross NAT and firewalls in the reverse traffic
23 direction (i.e. from outside to inside) so that n2n nodes are
24 reachable even if running on a private network. Firewalls no
25 longer are an obstacle to direct communications at IP level.
26 - n2n networks are not meant to be self-contained: it is possible
27 to route traffic across n2n and non-n2n networks.
