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.
