| JnxRpmMeasurementType |
|
| For each individual probe, several different measurements can be
made. These include the following (all measurements are provided
in units of microseconds):
roundTripTime -- this is the delay between the the transmission of
a probe and the arrival of its response.
rttJitter -- this is the difference between the current round trip
time measurement and the previous one.
rttInterarrivalJitter -- An estimate of the statistical variance
of a packet's interarrival time. Defined in rfc1889 as:
J=J+(|D(i-1,i)|-J)/16
where J is the interarrival jitter and D(i-1, i) is the current
round trip jitter measurement.
egress -- this is the delay beween the transmission of a probe and
its arrival at its destination.
egressJitter -- this is the difference between the current egress
delay the previous measurement.
egressInterarrivalJitter -- similar to rttInterarrivalJitter, but
applied to egress jitter measurements.
ingress -- this is the delay between the transmission of a probe
response and its arrival at its destination.
ingressJitter -- this is the difference between the current ingress
delay and the previous measurement.
ingressInterarrivalJitter -- similar to rttInterarrivalJitter, but
applied to ingress jitter measurements.
Note, not all types of measurements will be performed for every
probe. The jitter measurements are available only for those RPM
entries that employ hardware timestamps. Further, the ingress &
egress measurements are available only for those probe types that
measure one-way delays or where hardware timestamps are
employed and the one-way-hardware timestamp knob is enabled.
In either case, the one-way delays must be less than the round
trip times, otherwise they are discarded.
Also note, due to clock synchronization artifacts, many one-way
jitter measurements & calculations may include signifacant variations,
in some cases orders of magnitude greater than the round trip times.
Because of this, one-way jitter measurements will only be performed
on samples which are less than 10 seconds apart. |

over a single collection of probes. For each RPM entry, there
are several collections maintained: the current test, the
most recently completed test, a configurable number of the most
recent probes (aka 'moving average'), and a global collection
representing all the probes. Each entry in this table summarizes
the results for one of these collections. |

1.3.6.1.4.1.2636.3.50.1.4 |
| This table provides measurements for individual RPM probe samples.
In addition to the last completed sample, a configurable number of
the most recent samples are available as well. Within each sample,
the specific measurement type is identified by
jnxRpmHistSampleType. Note, if probe was unsuccessful, no
measurement types will be available for that history entry.
See the definition of JnxRpmMeasurementType for details on
the types of measurements available. |
