f0ddbe62f8 Netflow V5 is largely working. Still a few kinks to work out, but the exporter sends them out - and they are received correctly by my test ehnt setup. 2024-03-05 09:31:49 -06:00

1ac7a44355 Stage 1 of the revamp. Instead of modifying traverseNetwork directly, builds a layer per CPU in the network and then uses the previous code. 2024-03-01 14:28:36 -06:00

fcf07db112 On flat networks, read calculated LTS (or not) weights and apply them to the binpacking circuit weights if found. This makes binpacking more dynamic for flat networks, taking into account usual usage patterns. 2024-03-01 12:12:32 -06:00

370b65fa67 Compromise on 10ms sampling time for rate estimation. Giving pretty accurate results on my tests, and not hitting the CPU too hard. 2024-02-29 11:19:35 -06:00
Herbert Wolverson
23f2cfb9d8 Reduce the flow rate estimation frequency from 1 second to 1 ms.
This reduces round-error issues and is generally more accurate -
at the expense of slightly higher CPU usage and a "more bouncy"
rate - that is, for a widely variable flow such as Netflix it
jumps around a lot more. I remain unconvinced that 1ms is the
right number - will continue to test.

Thanks again to Simon Sundberg for this suggestion.

7d6cbd417a * Remove most code duplication by tracking rate_index and its reciprocal.
* Significantly nicer comments.
* I used a ternary operator. Please shoot me.

Thanks to Simon Sundberg for this recommendation.

393c3adc2a * Restore the tc_dissector, I didn't mean to remove that.
* Add SKB metadata support for pass-through and eliding the
  second LPM check if we can. Checks at run-time to see if
  it is possible.
