+NDR/PDR Binary Search
+=====================
+
+Algorithm Outline
+-----------------
+
+The ServiceChain class is responsible for calculating the NDR/PDR for all frame sizes requested in the configuration.
+Calculation for 1 frame size is delegated to the TrafficClient class.
+
+Call chain for calculating the NDR-PDR for a list of frame sizes:
+
+- ServiceChain.run()
+ - ServiceChain._get_chain_results()
+ - for every frame size:
+ - ServiceChain.__get_result_per_frame_size()
+ - TrafficClient.get_ndr_pdr()
+ - TrafficClient.__range_search() recursive binary search
+
+The search range is delimited by a left and right rate (expressed as a % of line rate per direction).
+
+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
+
