I wouldn't claim to know "how freenet works".
They do healing, so maybe there is something to be gained by understanding how their system works. >Longer HTLs mean the data gets > closer to the keyspace focus, which means it is MUCH more findable, and > improves routing. I think the effect of the data being inserted from many different points in the network is more important than the insertions htl. If you make the default htl too high people won't re-insert at all. >Low HTL reinserts just make it replicate a bit, > generally where it shouldn't be. >Of course I'd defer to Oskar here, but > that's my assessment. > > > --gj > > > > > > > Ian. > > > > > > > > -- > > > > * David 'Bombe' Roden > > > > ---------------------------------------- > > Content-Type: application/pgp-signature; charset="us-ascii"; > > name="Attachment: 1" > > Content-Transfer-Encoding: 7bit > > Content-Description: > > ---------------------------------------- > > > > _______________________________________________ > > devl mailing list > > devl at freenetproject.org > > http://hawk.freenetproject.org/cgi-bin/mailman/listinfo/devl ---------------------------------------- Content-Type: application/pgp-signature; charset="us-ascii"; name="Attachment: 1" Content-Transfer-Encoding: 7bit Content-Description: ---------------------------------------- _______________________________________________ devl mailing list devl at freenetproject.org http://hawk.freenetproject.org/cgi-bin/mailman/listinfo/devl
