Hi,
In udpif_revalidator(), the leader thread seems to adjust the datapath
flow_limit
in response to duration (which is the time taken to revalidate). It does this
with
some heuristic calculations that I have reproduced below. Not sure exactly why
it
is doing this or how the heuristics work as I would have assumed the flow_limit
would
be independent of revalidation time. Can anyone shed some light on that for me?
if (duration > 2000) {
flow_limit /= duration / 1000;
} else if (duration > 1300) {
flow_limit = flow_limit * 3 / 4;
} else if (duration < 1000 && n_flows > 2000
&& flow_limit < n_flows * 1000 / duration) {
flow_limit += 1000;
}
Thanks,
Mark
