Hello,
I've read a couple of times that Freenet has a problem with node discovery .
However this interpreted much to broadly, All you need to use Freenet is one
initial node and the discovery after that is actually handled pretty
elegantly using the actual datasource as a reference not the node the
request was ent to.
(I remeber it well when Ian pointed out this feature). So you'll accumalate
a list of nodes as you use the network. No problem there.
The problem Freenet has with node discovery is that 'new' nodes don't get
incorporated into the network, as in no requests will be routed towards
them. This means all the juicy resources the new nodes offer aren't used.
That is what the Inform.php is for, to 'anounce' new nodes. Not to discover
nodes in the network.
I think this could be addressed by tweaking the way Freenet chooses the
refernce in the datastore a bit.
When servicing a request the node knows of 4 locations the data can be
found.
- node 1 the datasource
- node 2 the node the reply is comming from
- node 3 the node itself
- node 4 the node it forwarded the reply to.
We already implemeted a random possibillity that the first and the seccond
node are the same this done by node 2 by resetting the datasource to itself.
I suggest we remove this and move this functionallity from where it resets
the datasource to where the reference is set (DataSend.java?).
The possibillities could be something like 90% node 1 8% node 2 and 2% node
4; (I guess we need to simulate)
This would mean that there is a 2% chance your node will be 'discovered' if
you make a request so all you need to do to get incorperated into freenet is
make enough requests.
Neil
