The search range is delimited by a left and right rate (expressed as a % of line rate per direction).
+The load_epsilon configuration parameter defines the accuracy of the result as a % of line rate.
+The default value of 0.1 indicates for example that the measured NDR and PDR are within 0.1% of line rate of the
+actual NDR/PDR (e.g. 0.1% of 10Gbps is 10Mbps). It also determines how small the search range must be in the binary search.
+
The recursion narrows down the range by half and stops when:
- the range is smaller than the configured load_epsilon value
- or when the search hits 100% or 0% of line rate
