Frame Loss Configuration

The objective of this test is to find the percentage of frames that are lost

due to lack of resources. Starting at full media speed, the test is performed

for a specific frame size and for the specified duration (Test Time). The test

is repeated by decreasing the throughput by the specified granularity (Test

granularity), then the test is repeated again until there are two successive

trials in which no frames are lost. The test performs the defined number of

trials (Nb of trials to average). At the end, the results are validated the

number of times specified (Final result validation). The test is performed

for each defined frame size.

Press Main, Test, RFC 2544, Configuration, and Frame Loss.

Note: Frame Loss must be enabled from Global Configuration on page 252.

Configuration

 Test Time (MM:SS): Select the test time value. Possible values are 1

second to 30 minutes. The default setting is 1 second (00:01).

 Test Granularity (%): Select the test granularity. The test granularity is

the percentage interval between each throughput value used for the

test. For example, 10% granularity means that the test will be

performed for 100%, 90%, 80%... of the throughput value. Choices are 1

to 10% (RFC). The default setting is 10%.
