            Simple Two-Way Direct Loss Measurement Procedure
                draft-gandhi-ippm-simple-direct-loss-00

Abstract

   This document defines Simple Two-Way Direct Loss Measurement (DLM)
   procedure that can be used for Alternate-Marking Method for detecting
   accurate data packet loss in a network.  Specifically, DLM probe
   packets are defined for both unauthenticated and authenticated modes
   and they are efficient for hardware-based implementation.

1.  Introduction

   Many Service Provider Service Level Agreements (SLAs) depend on the
   ability to measure performance loss metric experienced by the
   Customer data traffic flow.  The accurate Customer data packet loss
   can be measured by using the Direct Loss Measurement (DLM)
   procedures.  Currently there is no efficient active measurement
   procedure available for accurate data packet loss detection in IP
   networks.  Note that an approach for conducting packet loss
   measurement in IP networks is documented in [RFC7680].  This approach
   requires clock synchronization between the measurement points and
   lacks support for accurate data packet loss measurement.
