In a Netsukuku network each node can have more than one link towards more than one neighbor
node. Usually you start with a link with a neighbor, and this is enough for a good experience.
But at any moment, you can upgrade your connectivity, for instance by mounting more antennas
on your roof which connect to more nodes. Your node will, in many occasions, exploit all the
capacity of all the links.

This is mostly unseen in Internet today. Due to its centralized architecture, you get only one gateway
and it is very hard to setup a solution where one can effectively sum up the capacity of, say, two separate
Internet DSL lines.

In netsukuku, when you are already connected and you setup a direct connection with a new
neighbor, you are helping your neighbor. But at the same time you are helping the whole
network to grow, and you are helping yourself too. In fact, you are setting up another path
for your computer and that path could become in future a precious link for you to exploit.
