Netsukuku features list

- The Netsukuku mesh network is: distributed, not hierarchic, and higly
  scalable. It isn't specifically designed for mobile nodes, since the
  stability of the net was prioritised. 
  However it can be used for them if they are inside an area covered by other
  Netsukuku nodes.

- Scalability: Netsukuku is specifically designed to handle an unlimited
               number of nodes with minimal CPU and memory resources.

        - The net isn't overloaded with discoveries packet
        
        - The size of the maps is fixed: about 4Kb for the int_map and 16Kb
          for  the ext_map.
          
        - Not all the nodes sends a broadcast discovery.
        
        - There are few floods for each discovery.
        
        - When a node receives a flood it has already the routes that can be
          used to reach all the nodes traversed by the flood. It doesn't need
          to calculate anything about them.
          
        - A flood is synchronized: the same flood starts at the same time for
          all the nodes.

- zeroconf: the network builds itself, without need of human intervention

- ANDNA: distributed and not hierarchic DNS

        - When the net becomes larger, ANDNA scales more because its DB will
          be distributed among the nodes.
          
        - Any node can register up to 256 hostnames.

        - The registration is secure: it is based on asymmetric cryptography,
          thus it is very difficult to take hostnames which has been already
          registered by other nodes.

        - Each hostname can be a string of maximum 512 bytes.
        
        - DNS compatibility: all the network programs are already compatible
          with ANDNA, because NetsukukuD comes with a DNS wrapper which
          converts DNS queries to ANDNA requests.
          
        -  All the resolved hostnames are kept, in the "resolved hostnames
           cache" to speed up the resolution process. 
           The rhcache is synchronized with ANDNA, therefore its stored
           entries will expire exactly when the registered hostnames expire
           in ANDNA.
        
        - Scattered Name Service Disgregation
          http://lab.dyne.org/Ntk_SNSD
          The SNSD is the ANDNA equivalent of the SRV Record of the Internet 
          Domain Name System, which is defined here:
          http://www.ietf.org/rfc/rfc2782.txt
          SNSD isn't the same of the "SRV Record", in fact, it has its own
          unique features.

- Internet compatibility
        - internet sharing
                * Multi-inet-gateways. 
                  The Netsukuku nodes will now automatically use multiple
                  inet-gateways to connect to the Internet, therefore their
                  Internet connection will be effectively load-balanced.
                  
                * Anti-loop multi-igw shield. 
                  The nodes which share their Internet connection will also
                  automatically use the shared connection of the other nodes.
                  Through a simple marking system, death loops are avoided.
                  
                * Traffic shaping.
                  The nodes which share their Internet connection can now
                  shape it, in this way they'll prioritize their local
                  outgoingtraffic and the lowdelay one (f.e. SSH).

- Routes based on bandwidth and latency
  http://lab.dyne.org/Ntk_bandwidth_measurement

- NetsukukuD:
        - low memory and CPU usage
                - it can run smoothly on a small Access Point
                
        - Support for multipath routes: to reach a destination node, the
          packets will use, at the same time, more than one route.
          
        - support for multi network interfaces
        
        - Multi interfaces multipath: if the node can reach a rnode trough
          multiple interfaces, it uses them all with a multipath route.
