Yeah, I know. I wanted to compare a 'normal' TCP/IP connection
with a 'normal' Protocoll ('http' - could have been FTP, edonk...)
with the freenet protocoll.
With my assumptions I have calculated a percentage, that is lost
by using http over tcp/ip compared to the total bandwidth.
And got that I can use 80%, thus loose 20% to routing, commands
-- overhead.
Next I tried to do the same with freenet, with the knowledge I have
about it.
Since I (and the others) do not have a direct connection to the host,
they must use the bandwidth of the other freenet users. Thus the ratio
compared to the http over tcp/ip must be much less. Because if I use
bandwidth from others, they will use mine, too - And most of the time
at the same ratio.
So now I tried to figure out, how much band-width is lost and got with my
assumptions something around 20% - where you say I'm wrong.
Has somebody done a calculation - experiment figuring out, how good the
actual routing is (like take a netto traffic of 5 MB data and calculate the
brutto amount of data for routing) - next calculate how much bandwidth it
consumes for each node, the calculate the percentage between the total
bandwidth and the netto Bandwidth for data.
Have you a better assumption for freenet ? It is very hard to make an
assumtion from 'varies very much'. Varies very much with an average of 7 hops
is more helpfull...
