  1. == Netsukuku and ICT infrastructure in the Developing World ==
  2. {{{
  3. Netsukuku network: enabled self-made and self-sustained ICT infrastructure
  4. for developing countries.
  5. The end-users, in order to connect their PC to the rest of the World
  6. through the Internet, have to make a subscription with an Internet Operator.
  7. The Domain Names, as well, are the unique way by which a network attached
  8. device (which could consist of a computer, a file server, a network storage
  9. device, a fax machine, a cable modem, etc.) is known on the Internet,
  10. and are literally sold through the centralised system of the Domain
  11. Name System (DNS). Netsukuku, an Open Source software, downloadable
  12. from http://netsukuku.freaknet.org makes possible the creation of a
  13. new distributed global Net, expandable to an unlimited number of users,
  14. alternative, independent and totally apart from the Internet.
  15. The Netsukuku particular routing system, created by some members of the
  16. "Freaknet" group of Catania (Italy), allows the Net to be self-sustained,
  17. thanks to all the Net users, that share a small part of their own PC
  18. resources. Anybody has the chance to join the Net and, at the same time, to
  19. let other users do the same.
  20. In those countries and areas of the globe where Internet facilities are still
  21. not available, a public Net can be created and developed in a very simple way
  22. (i.e. through a wi-fi coverage), without depending on any Internet Operators.
  23. In the same way, all the contents holder will be able to share any documents
  24. simply from their PC, since a maximum of 256 hostnames can be recorded and
  25. automatically supported by each PC (i.e. node of the Net).
  26. Last but not least, inside Netsukuku Net all the users will have the chance to
  27. get through the Internet: in fact any user can get the connectivity to
  28. Internet from other users that share and devolve into the net the bandwidth
  29. they don't use at the moment.
  30. Netsukuku routing system differs from all the other protocols and algorithms:
  31. the existing dynamic schemes are solely utilised to create small and medium
  32. nets.
  33. The routers of Internet are also managed by different protocols as the OSPF,
  34. the RIP or the BGP, all based on different classical algorithms.
  35. These algorithms are able to find out the best path to reach a node in the
  36. net, but require a very high waste of CPU and memory. That's why inside
  37. Internet, all the routers are powerful computers specifically dedicated to
  38. this purpose. On the contrary, when a node hooks to Netsukuku, the net
  39. automatically rewrites itself, while all the other nodes, using a very small
  40. part of the CPU and of the memory resource (a few kb), recognised which are
  41. the fastest and more efficient routes to communicate with the new arrived.
  42. The nodes don't have privileges or limitations: when compared to other nodes,
  43. they are part of the net and give their contribution to its expansion and
  44. efficiency. The more they increase in number the more the net grows and
  45. becomes stable. In Netsukuku there is no any difference between private and
  46. public nets and talking about LAN become meaningless.
