                  Precise Network Measurement Protocol
                        draft-yang-ippm-pnmp-00

Abstract

   PNMP, precise network measurement protocol, is used for out-of-band
   network measurement.  As 5G is continuously evolving, there become
   many more time sensitive services which require high precision of
   measurements.  In addition, in order to better simulate the
   transmission of packets of monitored services, the length and
   priorities of the measurement packets SHOULD be customized,
   especially for some network that is inclined to get congested.  PNMP
   can not only support PTP, precise time protocol, but also allow some
   customization on packet payload.  It only introduces a little
   overhead by adding an extendable header over IP header.

1.  Introduction

   The precision of some conventional ways used to measure the one-way
   or round-trip delay and jitter, including ICMP (ping command) and
   Iperf, a measurement tool, is highly dependent on
   NTP[RFC5905]precision which is between millisecond and second.  As 5G
   has arisen and it is still continuously evolving, many industrial
   scenarios, such as internet of vehicles, and other time sensitive
   services have new requirements for time precision which is in
   microsecond and even in nanosecond.  With the growing support of
   Precision Time Protocol (PTP) [IEEE.1588.2008], in many industrial
   scenarios, such as industrial control network and video transmission
   network, devices can be synchronized in very high precision that is
