From what I've seen, Windows operating systems do not allow multiple
connections to
the internet to be active at once, which means that only one such
connection can be reachable
from BOINC at any one time.

Hello gyus,
Maybe it would be preferably to let user choose the connection BOINC uses
for download/upload?
So in this case BOINC need to detect all available connections and make a
checkbox list where user can choose which connection should be used when
available?
Because doind automated testing of connection speed is not good for these
purposes.
Thanks
Best regards,

We have had this discussion before -- back in the days when dialup was
common. Without doing an end to end test of the connection there is no way
to tell what the connection speed is. Dialup is still the way things are
in some places in the world. Based on dialup with a router and a switch, I
can have a 1Gb connection locally but only a 1.3Kb connection to the
outside world, and the computer cannot know without doing an end to end
test. With ADSL links (much more common at the moment) it is possible to
have a 1Gb connection locally and a 5Mb connection to the outside world.
Running a check like this against some BOINC BOINC projects could tip them
over into congestion where nothing gets through.
So, it would require:
A selection for what high speed meant.
A checkbox to indicate if enabled.
An end to end check to see what the connection speed was.
Some idea of when to use it as doing an end to end connection check when
there was only a few hundred bytes to transfer does not seem reasonable.
At the time it was decided that this was not something we wanted to
pursue. Of course, this can change.

Hi Charles,
With the increasing prevalence of mobile computing devices then having the
system (scheduler) doing the test is not really scalable as people move
their devices.
It would be much easier if the clients did this. My Mac for example is
able to tell me the latest network bandwidth if has for any of its
interfaces.

Boinc could just download a test file from the Oxford website 5 times and
average the times. If the average was above a limit deemed the minimum
acceptable speed, the user would be permitted to proceed. OW, the Oxford
website would post a very polite, very detailed, and very well written
message to Boinc/the user explaining why a high bandwidth connection is
necessary for the user's progress and enjoyment of Oxford's project.
One of the Boinc GPU projects, as I recall in Spain, does this now WRT the
capacity of the user's GPU(s). It is no fun for, or use to, anyone if the
user processes a work unit on an older GPU, the GPU overheats, and the WU
fails 3/4 of the way through. It is annoying though.

Hi,
We would be interested in an additional BOINC preference, a tickbox on
the 'Network' tab, with something like 'Download only when connected to a
high bandwidth connection'. Ticking the box of this preference would
prevent download of the application and supporting files when the machine
(for example: a laptop) was connected only to WiFi and not connected to a
higher bandwidth networking cable. Would it be possible for this to be
scheduled to be added as an item to be included in a later release?
With regards,
What does "high bandwidth connection" mean, how could BOINC know if it's
connected to one?
