Just wondering when you do your statistics if you condition your rates on
"new" attempts.  For users that it works, it will continue to work and these
users will form multiple connections and for users that is does not work,
they will not try to form more connections..basically, if you just looked at
connection formation rates it will be unfairly weighted.  However, I too do
believe even "new" connection rates in the 90+ percentile is possible if you
use a variety of techniques.

Hi Alex,

I do care, but, sorry, can't share. It is not 99% though, I can tell you
this much. At some point I made a comment on this list, that 97-98% should
be achievable. Since then we added TCP NAT traversal and a handful of UDP
traversal tricks. On other hand Hamachi's userbase profile has changed.
Specifically, the percentage of home users (behind dumb routers) declined in
favor of people behind proxies and other funny devices (e.g. load
balancers). We got more people connecting from far places (hop count and
latency-wise) as well. So the number works out to be about the same as it
was before. With just the home users I suspect we would've been in 95-97%
range, though I might be off.


Do you mean 95-97% for both TCP and UDP? 

UDP mostly. TCP tunnels account for under 2% in our system, and the number
should be even lower if we are looking at the home users only.

 

Alex
