This document describes an alternative to throughput in "Benchmarking 
Methodology for Network Interconnect Devices" (RFC 2544) by defining a new 
methodology called Multiple Loss Ratio Search (MLRsearch). MLRsearch aims to 
minimize Search Duration, support multiple loss ratio goals, and improve result 
repeatability and comparability.

MLRsearch is motivated by the pressing need to address the challenges of 
evaluating and testing the various data plane solutions, especially in 
software-based networking systems based on Commercial Off-the-Shelf (COTS) CPU 
hardware vs. purpose-built Application-Specific Integrated Circuit (ASIC) / 
Network Processing Unit (NPU) / Field-Programmable Gate Array (FPGA) hardware.

This document is a product of the Benchmarking Methodology Working Group of the 
IETF.
