   Probabilistic Loss Ratio Search for Packet Throughput (PLRsearch)
                     draft-vpolak-bmwg-plrsearch-01

Abstract

   This document addresses challenges while applying methodologies
   described in [RFC2544] to benchmarking software based NFV (Network
   Function Virtualization) data planes over an extended period of time,
   sometimes referred to as "soak testing".  Packet throughput search
   approach proposed by this document assumes that system under test is
   probabilistic in nature, and not deterministic.
