3. Utilisation. As above, but both the
preamble and inter-packet gap (IPG, 12
bytes) are included.

Include Tags

Where packets are tagged, the tag bytes may
be included or excluded for IR purposes.
Separate controls are available for c-tags, s-
tags and tags that are to be added by
external equipment.

9.1.3 Performance Parameters

FLR

Frame Loss Ratio

FLR specifies the maximum acceptable
number of packets that are not delivered, as
a percentage of the total packet count.

FTD

Frame Transfer Delay
(Latency)

FTD specifies the maximum acceptable
delay that is placed on the packet as it
passes over the service.

IFDV

Inter-Frame Delay
Variation (Jitter)

IFDV specifies that maximum acceptable
variation in the FTD between adjacent
packets passing over the service.

Availability

Availability specifies the amount of time (as a
percentage of the total) that the service is
'available'. The available status is derived
from the SES performance (see below) using
a filtering algorithm. The other performance
parameters only relate to available time.

9.1.4 Others

SES
Threshold

Severely-Errored
Second Threshold

In order to determine the availability status
(see above), Severely-Errored Seconds must
be identified. These are defined as 1-second
intervals where the FLR exceeds the
specified threshold value.
