D2forD1
Enable to use DMM/DMR packet to calculate one-way DM. If the option is enabled,
the following action will be taken. When DMR is received, two-way delay (roundtrip
or flow) and both near-end-to-far-end and far-end-to-near-end one-way delay are
calculated. When DMM or 1DM is received, only far-end-to-near-end one-way
delay is calculated.
Counter Overflow
Action
The action to counter when overflow happens.
Delay Measurement State
Tx
The accumulated transmit count - since last 'clear'.
Rx
The accumulated receive count - since last 'clear'.
Rx Timeout
The accumulated receive timeout count for two-way only - since last 'clear'.
Rx Error
The accumulated receive error count - since last 'clear'. This is counting if the frame
delay is larger than 1 second or if far end residence time is larger than the round
trip time.
Av Delay Tot
The average total delay - since last 'clear'.
Av Delay last N
The average delay of the last n packets - since last 'clear'.
Delay Min.
The minimum delay - since last 'clear'.
Delay Max.
The maximum delay - since last 'clear'.
Av Delay-Var Tot
The average total delay variation - since last 'clear'.
Av Delay-Var last N
The average delay variation of the last n packets - since last 'clear'.
Delay-Var Min.
The minimum delay variation - since last 'clear'.
Delay-Var Max.
The maximum delay variation - since last 'clear'.
Overflow
The number of counter overflow - since last 'clear'.
Clear
Set of this check and save will clear the accumulated counters.
Far-end-to-near-end
one-way delay
The one-way delay is from remote devices to the local devices. Here are the
conditions to calculate this delay. 1. 1DM received. 2. DMM received with D2forD1
enabled. 3. DMR received with D2forD1 enabled.
Near-end-to-far-end
one-way delay
The one-way delay is from the local devices to remote devices. The only case to
calculate this delay is below. DMR received with D2forD1 enabled.
Delay Measurement Bins
A Measurement Bin is a counter that stores the number of delay measurements falling within a specified
range, during a Measurement Interval.
Measurement Bins
for FD
Configurable number of Frame Delay Measurement Bins per Measurement
Interval.
The minimum number of FD Measurement Bins per Measurement Interval
supported is 2.
The maximum number of FD Measurement Bins per Measurement Interval
supported is 10.
The default number of FD Measurement Bins per Measurement Interval supported
is 3.
