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.
