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.

Figure 3. Number of IP 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.
