The values on the Rate Test tab report the processing results of a test executed during PCRF Nodal testing.
In the default view, the Reports tab displays the Summary view, which summarizes the measurements for the test session. If your test includes multiple test cases, you can view the report for a single test case by changing the report view...
Unless otherwise noted, cumulative values report the number of occurrences or rates calculated since the start of the test, and per-interval values report the number of occurrences or rates calculated during the interval. You can view either by changing the measurement values...
Elapsed Time is the first measurement on every tab. It reports the amount of time between the start of the test and the end of the report interval.
Test Iteration reports the current iteration in a repeating test session. It is only displayed when a Number of Iterations is defined for the test session.
The following measurements display the test definitions in effect during the report interval and session errors, connections, and disconnections from the previous test run.
Interval Start Time — The start time for the current session loading run.
Current Hold Time — The effective hold time for the current session loading run. The hold time may be decreased by the Hold Backoff Amount for each test run depending on the errors encountered during the previous run and the error threshold defined in the test.
Current Pending Time — The effective pending time for the current session loading run. The pending time may be adjusted for each test run depending on the errors encountered during the previous run and the error threshold defined in the test.
Error Count of Previous Interval — The number of errors encountered during the previous session loading run. See the protocol report tabs for specific error measurements.
Connects in Last Interval — The number of sessions successfully established in the previous session loading run.
Disconnects in Last Interval — The number of sessions successfully disconnected in the previous session loading run.
Actual Rate of Previous Interval — The actual aggregate rate achieved for all session connects and disconnects in the previous session loading run. This rate is calculated by dividing the sum of Connects in Last Interval and Disconnects in Last Interval by the Session Loading Run Time. Assuming an error-free session loading run, this rate should match the Target Session Loading Rate displayed during the previous session loading run.
Target Session Loading Rate — The target aggregate rate of all session connects and disconnects that will be attempted in the current session loading run, taking into account the total number of MN sessions, Activation Rate, Deactivation Rate, Current Hold Time, and Current Pending Time. ExampleExample:
Assuming the following test configuration:
The defined run, hold, and pending times allow 5 full session loading cycles — the 100 sessions will be connected 5 times and disconnected 5 times for a total of 500 connects and 500 disconnects during the session loading run. The Target Session Loading Rate for the first session loading run is 3.33 sessions/second: (500 connects + 500 disconnects) / 300 seconds.
In the second session loading run, the hold and pending times are reduced to 25 seconds, allowing for 6 full session loading cycles and a total of 600 connects and 600 disconnects during the session loading run. Therefore, the Target Session Loading Rate for the second session loading run is 4 sessions/second: (600 connects + 600 disconnects) / 300 seconds.
Assuming that the session errors do not exceed the defined threshold, this rate will increase in each session loading run as the backoff amounts are applied to the hold and pending times.
Cumulative values report the number of sessions that are active at the end of the interval.
Per-interval values report the difference in the current number of active sessions and the number of sessions in the previous interval. A negative number represents the number of sessions disconnected during the interval.
Block Error Rate — The percentage of errors encountered in the previous activation or handoff run.
Block Test Rate — The activation or handoff rate, in sessions per second, used for the previous run.
