The minimum time
interval between the start of IP SLAs operations in a group operation is 1
second. Therefore, if the number of operations to be scheduled is greater than
the schedule period, the IP SLAs multiple operations scheduling functionality
schedules more than one operation to start within the same 1-second interval.
If the number of operations getting scheduled does not equally divide into
1-second intervals, the operations are equally divided at the start of the
schedule period with the remaining operations to start at the last 1-second
interval.

The following figure
shows the scheduling of operation 1 to operation 10 within operation group 3.
Operation group 3 has a schedule period of 5 seconds and a frequency of 10
seconds.

SLAs Operations Is Greater Than the Schedule Period—Even
Distribution

In this example, when
dividing the schedule period by the number of operations (5 seconds divided by
10 operations, which equals one operation every 0.5 seconds), the start time of
each IP SLAs operation is less than 1 second. Because the minimum time interval
between the start of IP SLAs operations in a group operation is 1 second, the
IP SLAs multiple operations scheduling functionality instead calculates how
many operations it should start in each 1-second interval by dividing the
number of operations by the schedule period (10 operations divided by 5
seconds). Therefore, as shown in the previous figure, two operations are
started every 1 second.

As the frequency is
set to 10 in this example, each iteration of operation group 3 will start 10
seconds after the start of the previous iteration. However, this distribution
is not optimal as there is a gap of 5 seconds (frequency minus schedule period)
between the cycles.

If the number of
operations getting scheduled does not equally divide into 1-second intervals,
then the operations are equally divided at the start of the schedule period
with the remaining operations to start at the last 1-second interval.

The following figure
shows the scheduling of operation 1 to operation 10 within operation group 4.
Operation group 4 has a schedule period of 4 seconds and a frequency of 5
seconds.

Figure 4. Number of IP
SLAs Operations Is Greater Than the Schedule Period—Uneven
Distribution

In this example, the
IP SLAs multiple operations scheduling functionality calculates how many
operations it should start in each 1-second interval by dividing the number of
operations by the schedule period (10 operations divided by 4 seconds, which
equals 2.5 operations every 1 second). Because the number of operations does
not equally divide into 1-second intervals, this number will be rounded off to
the next whole number (see the figure) with the remaining operations to start
at the last 1-second interval.
