N2N community vpn

• N2N node membership is rather static. Nodes usually register with a N2N community and stick with it as long as the node is operational. In other networks such as Gnutella or Napster the membership change rate is much higher and can lead to issues as the network topology might need to be changed in order to handle new members.• N2N nodes themselves do not store, cache, replicate or manage any content. This is because N2N connects network peers rather than content and consumers.• The goal of N2N is not to share files but rather to allow peers to communicate generically  in a secure way and to locate each other  by consistent addressing regardless of their physical network location.  Data sharing is accomplished by higher layer protocols as the Internet design intended.3. N2N Architecture and ImplementationEdge nodes run on a host that can be placed in a private or public LAN. Supernodes are used to introduce edge nodes and relay packets to an edge behind symmetrical NAT (which prevents it from being directly reachable by peers). With symmetric NAT all requests from the same internal IP:port to a specific IP destination:port are mapped to an external IP:port. If the same internal host sends a request with the same source address and port to a different destination, a different external mapping is used.
