Bin groups are templates that are referenced by the session. Three types of binnable statistics are available: FD, IFDV, and FDR, all of which are available in forward, backward, and round trip directions. Each of these metrics can have up to ten bin groups configured to group the results. Bin groups are configured by indicating a lower boundary. Bin 0 has a lower boundary that is always zero and is not configurable. The microsecond range of the bins is the difference between the adjacent lower boundaries. For example, bin-type fd bin 1 configured with lower-bound 1000 means that bin 0 will capture all frame delay statistics results between 0 and 1 ms. Bin 1 will capture all results above 1 ms and below the bin 2 lower boundary. The last bin to be configured would represent the bin that collects all the results at and above that value. Not all ten bins must be configured.
Each binnable delay metric type requires their own values for the bin groups. Each bin in a type is configurable for one value. It is not possible to configure a bin with different values for round trip, forward, and backward. Consideration must be given to the configuration of the boundaries that represent the important statistics for that specific service.
As stated earlier in this section, this is not a dynamic environment. If a bin group is being referenced by any active test the bin group cannot shutdown. To modify the bin group it must be shut down. If the configuration of a bin group must be changed, and a large number of sessions are referencing the bin group, migrating existing sessions to a new bin group with the new parameters can be considered to reduce the maintenance window. To modify any session parameter, every test in the session must be shut down.
Bin group 1 is the default bin group. Every session requires a bin group to be assigned. By default, bin group 1 is assigned to every OAM-PM session that does not have a bin group explicitly configured. Bin group 1 cannot be modified. The bin group 1 configuration parameters are as follows:
