Rfc2544ThroughputProfile Object


Description:

Defines throughput parameters for asymmetric test configurations. These parameters override parameters in the Config object for the streamblocks that are associated with it.

Rfc2544ThroughputProfile Writable Attributes

Attribute Description
Common Writable Attributes Active, Name
AcceptableFrameLoss

Maximum frame loss you want Spirent TestCenter to allow before stopping the test. This value represents the aggregate loss from all flows averaged across each all ports in the test.

Type: double

Default: 0

Range: 0.0 - 100.0

Backoff

Percentage by which the transmission rate will be lowered if the test fails at the current rate.

Type: double

Default: 50

Range: 0.001 - 99.999

EnableMaxLatencyThreshold

Whether the search algorithm uses the maximum latency per stream to determine the throughput.

Type: bool

Default: FALSE

Possible Values:

Value Description
TRUE

Search algorithm uses the maximum latency per stream to determine the throughput.

FALSE

Search algorithm does not use the maximum latency per stream to determine the throughput.

EnableOutOfSeqThreshold

Select this field to enable the Out of Sequence Threshold field.

Type: bool

Default: FALSE

Possible Values:

Value Description
TRUE

Enable the Out of Sequence Threshold field.

FALSE

Disable the Out of Sequence Threshold field.

IgnoreMinMaxLimits

Enable the application to automatically define a Min Rate /Max Rate range that successfully yields throughput.

Type: bool

Default: FALSE

Possible Values:

Value Description
TRUE

Continue beyond minimum or maximum.

FALSE

Restricted between minimum and maximum.

LoadSpecMode

Load for this profile.

Type: enum

Default: PER_PORT

Possible Values:

Value Description
PER_PORT

Total load per port.

PER_STREAMBLOCK

Total load for each streamblock.

LoadUnits

Unit of measurement for the load parameter, applied to all ports and streams in the test.

Type: enum

Default: PERCENT_LINE_RATE

Possible Values:

Value Description
PERCENT_LINE_RATE

Load expressed in a percentage.

FRAMES_PER_SECOND

Load expressed in frames per second.

MEGABITS_PER_SECOND

Load expressed by megabits per second.

KILOBITS_PER_SECOND

Load expressed by kilobits per second.

BITS_PER_SECOND

Load expressed by bits per second.

MaxLatencyThreshold

Maximum (in uSec) of all the average latencies determined on each receive port in the test. If the threshold is reached, then the test iteration fails.

Type: double

Default: 30

Range: 0.01 - 4294967295.0

OutOfSeqThreshold

Number of out-of-order frames on each receive port that, if exceeded,will cause the test iteration to fail.

Type: u32

Default: 0

Range: 0 - 2147483647

RateInitial

Transmission rate for the first iteration of the test. This is a percentage of the full wire rate.

Type: double

Default: 10

RateLowerLimit

Lowest transmission rate at which the application will send traffic during any test iteration, as a percentage of the total wire rate.

Type: double

Default: 1

RateStep

Percent by which Spirent TestCenter will increase the current transmission rate, as a percentage of the total wire rate. The transmission rate increases until the maximum rate is reached, even if there is frame loss.

Type: double

Default: 10

RateUpperLimit

Maximum rate at which Spirent TestCenter will send traffic during the test,as a percentage of the total wire rate.

Type: double

Default: 100

Resolution

Minimum allowable delta between the highest passed transmission rate and the lowest failed transmission rate.

Type: double

Default: 1

Range: 0.001 - 100.0

SearchMode

Mode used to find the throughput rate.

Type: enum

Default: BINARY

Possible Values:

Value Description
BINARY

Test searches for the throughput value by using a binary search algorithm.

STEP

Test load increases with each iteration by the percentage specified by step load.

COMBO

Mode begins in Step mode, then changes to Binary mode when the step adjustment causes failure.
