2. Delay statistics are provided by means the point-to-point, Ethernet frame transfer
delay (FTD): current, minimum, maximum, and mean values. FTD statistics follow
definitions given in ITU-T Y.1563
3. Delay variation statistics are provided by the following statistics: standard devia-
tion of the FTD, peak FDV (difference between maximum FDV and minimum
FDV), current jitter (smoothed value of the jitter following RFC 1889 and
RFC 3393), maximum jitter, mean jitter.
4. Frame reordering and duplication statistics (RFC 5236): Out-of-order frames, Out-
of-order frame ratio, duplicated frames, duplicated frame ratio.
5. Frame loss statistics to be used is the lost frames count and the 2-way Ethernet
Frame Loss Ratio (FLR).
6. Availability statistics: Severely Errored Seconds (SES) count, Percent Ethernet
service Unavailability (PEU), Percent Ethernet service Availability (PEA).
A.12.6.Service Disruption Time
1. Simultaneous per port statistics. Analysis carried out over flow 1 statically.
2. Service Disruption test based on the analysis of the SLA pattern carried by a syn-
thetic traffic flow.
3. Resolution is 1 ms.
4. Statistics are service disruption events count. Total disrupted time. Average, mini-
mum and maximum time in a service disruption event. Time in the last disruption
event.
A.12.7.BER
1. Simultaneous per port statistics. Analysis carried out over flow 1 statically.
2. Bit error count, seconds with errors, bit error ratio (BER).
3. Pattern losses, pattern loss seconds.
A.12.8.Network Exploration
1. Simultaneous per port results for a single search field.
2. Top talkers statistics: Displays the 16 most common source MAC addresses
(Ethernet Endpoint mode) or source MAC / IPv4 / IPv6 addresses (IP Endpoint
mode).
3. Top VID (IEEE 802.1Q) statistics: Displays the 16 most common VID tags.
4. Top S-VID (IEEE 802.1ad) statistics: Displays the 16 most common S-VID tags.
5. Automatic setup of the eight available filtering blocks to match the items found in
the top talkers list.
