4.4.4. Calibration
Section 3.7.3 of [RFC7679] provides a means to quantify the
systematic and random errors of a time measurement. In-situ
calibration could be enabled with an internal loopback that includes
as much of the measurement system as possible, performs address
manipulation as needed, and provides some form of isolation (e.g.,
deterministic delay) to avoid send-receive interface contention.
Some portion of the random and systematic error can be characterized
this way.
When a measurement controller requests a calibration measurement, the
loopback is applied and the result is output in the same format as a
normal measurement with additional indication that it is a
calibration result.
Both internal loopback calibration and clock synchronization can be
used to estimate the *available accuracy* of the Output Metric Units.
For example, repeated loopback delay measurements will reveal the
portion of the Output result resolution which is the result of system
noise, and thus inaccurate.

5.4.4. Calibration
Section 3.7.3 of [RFC7679] provides a means to quantify the
systematic and random errors of a time measurement. In-situ
calibration could be enabled with an internal loopback that includes
as much of the measurement system as possible, performs address
manipulation as needed, and provides some form of isolation (e.g.,
deterministic delay) to avoid send-receive interface contention.
Some portion of the random and systematic error can be characterized
this way.
For one-way delay measurements, the error calibration must include an
assessment of the internal clock synchronization with its external
reference (this internal clock is supplying timestamps for
measurement). In practice, the time offsets of clocks at both the
source and destination are needed to estimate the systematic error
due to imperfect clock synchronization (the time offsets are
smoothed, thus the random variation is not usually represented in the
results).
time_offset The time value of the result is expressed in units of
seconds, as a signed value of type decimal64 with fraction digits
= 9 (see section 9.3 of [RFC6020]) with resolution of 0.000000001
seconds (1.0 ns), and with lossless conversion to/from the 64-bit
NTP timestamp as per section 6 of RFC [RFC5905]
When a measurement controller requests a calibration measurement, the
loopback is applied and the result is output in the same format as a
normal measurement with additional indication that it is a
calibration result. In any measurement, the measurement function
SHOULD report its current estimate of time offset as an indicator of
the degree of synchronization.
Both internal loopback calibration and clock synchronization can be
used to estimate the *available accuracy* of the Output Metric Units.
For example, repeated loopback delay measurements will reveal the
portion of the Output result resolution which is the result of system
noise, and thus inaccurate.

<Full bibliographic reference to an immutable doc.> <Full bibliographic reference to an immutable doc.>
Almes, G., Kalidindi, S., and M. Zekauskas, "A Round-trip Delay
Metric for IPPM", RFC 2681, September 1999.
<specific section reference and additional clarifications, if needed> <specific section reference and additional clarifications, if needed>
Section 2.4 of [RFC2681] provides the reference definition of the
singleton (single value) Round-trip delay metric. Section 3.4 of
[RFC2681] provides the reference definition expanded to cover a
multi-value sample. Note that terms such as singleton and sample are
defined in Section 11 of [RFC2330].
Note that although the definition of "Round-trip-Delay between Src
and Dst at T" is directionally ambiguous in the text, this metric
tightens the definition further to recognize that the host in the
"Src" role will send the first packet to "Dst", and ultimately
receive the corresponding return packet from "Dst" (when neither are
lost).
