{{{
|
|
|
|
- The Netsukuku mesh network is: distributed, not hierarchic, and higly
|
|
scalable. The design of Netsukuku prioritises the stability of net.
|
|
For this reason, it isn't specifically suitable for mobile nodes.
|
|
However if the mobile nodes are inside an area covered by static Netsukuku
|
|
nodes, there aren't any problems. It is also possible to use other mesh
|
|
network protocols designed for mobility in conjunction with Netsukuku (f.e.
|
|
see olsrd.org), in the same way they are used in conjunction with the
|
|
Internet.
|
|
|
|
- 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.
