Performance Monitoring (PM) Profile
Performance Monitoring (PM) profile is used for the traffic statistics of all ONUs (ONTs)
collected by an OLT. The ONT conceptually has only two storage bins: a current accumu-
lator and a history bin. The current accumulator is used to store data collected for the cur-
rent 15-minute interval. The history bin is used to store data for the previous 15-minute in-
terval. At the end of the current 15-minute interval, they switch roles: the previous accu-
mulator bin becomes the new history bin, while the content of the history bin is discarded
and the bin itself is initialized as the new accumulator.The ONT performs no calculations
upon the collected data nor does it keep an archive of collected data beyond the previous
15-minute interval. All calculations based on collected data and archiving of past intervals
is performed by the OLT.
