Paradyne 9123 manual Average round trip latency is measured every SLV sampling

Operation and Maintenance

Table 5-12. Service Level Verification Performance Statistics (2 of 2)

Statistic

What It Indicates

H Above EIR *	H The number of frames transmitted by the far-end device that
	were above the excess information rate and were dropped
	in transit.
Inbound Dropped	Total number of bytes transmitted by the far-end device that
Characters *	were dropped in transit.
	The counts continue to increment until the maximum value is
	reached (232 ±2), then the count starts over.
	The SLV Delivery Ratio option (see Table 3-2, Service Level
	Verification Options) must be enabled for these statistics to
	appear. NA appears instead of a statistical count if FDR/DDR
	(Frame Delivery Ratio/Data Delivery Ratio) information is not
	being received from the far-end device .
H Above CIR *	H The number of bytes transmitted by the far-end device that
	were above the committed information rate and were
	dropped in transit.

HWithin CIR *

HThe number of bytes transmitted by the far-end device that were within within the committed information rate, but were dropped in transit.

HBetween CIR&EIR *

HThe number of bytes transmitted by the far-end device that were between the committed information rate and excess information rate, and were dropped in transit.

H Above EIR *	H The number of bytes transmitted by the far-end device that
	were above the excess information rate and were dropped
	in transit.
Latest RdTrip Latency	Current round trip latency, measured in milliseconds, between
	the FrameSaver unit and the device at the other end of the
	multiplexed DLCI connection.
	Unknown appears if communication with the far-end device is
	not successful.
Avg RdTrip Latency	Average round trip latency, measured in milliseconds, between
	the FrameSaver unit and the device at the other end of the
	multiplexed DLCI connection.
	Average round trip latency is measured every SLV sampling
	interval and the average is computed (using packets with the
	configured SLV Packet Size (bytes), Table 3-2, Service Level
	Verification Options) over the previous 15-minute period. If
	SLV Packet Size is changed, a new average is not available
	until a new sample has been received.
	Unknown appears if communication with the far-end device
	over the last 15 minutes has not been successful.
Max RdTrip Latency	Same as average (Avg RdTrip Latency), but storing the
	maximum value of latency over the previous 15-minute
	interval.
	Unknown appears if communication with the far-end device
	over the last 15 minutes has not been successful.

*Only appears for FrameSaver units when the SLV Delivery Ratio option is enabled.
