Y.1564 Test configuration (Service Performance ▶ Y.1564 ▶ Configuration)

ParameterDescription
Source deviceDevice that will be the source of the test.

When you click in this field, a dialog pops up. You can select a device from the Skylight orchestrator inventory

General

ParameterDescription
Test nameA name for the Y.1564 test profile.

A maximum of 28 characters is supported. Do not include spaces, forward slashes, or backslashes in the name.

Test descriptionA description to identify the Y.1564 test and its characteristics.
Delay measurement typeThe delay measurement type can be either one-way delay or two- way delay

Note: You must enable the SAT protocol in order to use one-way delay measurements.

Outgoing portThe port on which to send flow(s).
Device time SYNC mandatoryCheck box to enable or disable mandatory device sync time. When this option is enabled, the tests will be performed only if both devices performing the Y.1564 test are synchronized using one of the supported timing mechanisms.

When this option is disabled, the tests will be performed, but valid results will be displayed only if both devices performing the Y.1564 test are synchronized using one of the supported timing mechanisms. This type of test may be useful to test applications where delay is not important, but other parameters, such as CIR or EIR, are important.

Note: For one-way delay measurement only.

Duration

ParameterDescription
Configuration step duration (seconds)The duration, expressed in seconds, of each step during the configuration test.

Range: 1–60 seconds.

Note: This parameter is also used for the burst SLA Test.

Performance step duration (minutes)The duration of the performance test, expressed in minutes.

Range: 1–1,440 minutes

Enable configuration testCheck box to enable the configuration test allows use of the policing test and step test under each service (traffic flow) configured.

It allows you to run successive tests at rates of 25% CIR, 50% CIR, 75% CIR, and 100% of CIR, CIR+EIR, and Policing.

For Policing:

  • If EIR < 20 % x CIR, Policing Rate = (125 % x CIR) + EIR
  • If EIR ≥ 20 % x CIR, Policing Rate = CIR + (125 % x EIR)
Enable performance testCheck box to enable or disable the performance test.

You must configure at least one service when you enable performance test.

Note: The performance test is run at 100% CIR.

Enable parallel testCheck box to enable or disable the Parallel Service Configuration test.
  • Enable: All enabled services (traffic flows) are run simultaneously.
  • Disable: All enabled services (traffic flows) are run sequentially.
Enable burst SLA testEnable or disable the burst SLA test. (Default is disabled)

General far-end settings

ParameterDescription
Test typeThe type of test traffic:
  • Layer-2: Y.1731 LBM frames.
  • Layer-2 Accedian: Y.1731 LBM frames marked with the Accedian Ethertype.
  • Layer-2 generic: Special Y.1731 OpCode frames to be used only with loopback devices based on the MAC-address swap.
  • Layer-3: UDP segments to perform a test across a multilayered network.
Group reverse tests
  • Checked: Skylight orchestrator creates only one test for each remote unit that is featured in an enabled flow having the OW Reverse Path option checked.
  • Unchecked: Skylight orchestrator creates one test for each enabled flow of all remote units that have the OW Reverse Path option checked.
Note: Applies to Layer-3 tests only.
Near-end UDP portThe near-end UDP port number used to generate the test's PDU.

Note: Applies to Layer-3 traffic only.

Far-end UDP portThe far-end UDP port number associated with the IP address of the unit that will receive, process and display the traffic statistics and report.

Notes:

Applies to Layer-3 traffic only.

For reporting to work properly, you must set the port to a value in the range of 0–65535 but you cannot set the destination port value to 8793, since this is Accedian's proprietary port number. For information on destination ports default values, refer to.

General (flow parameters)

ParameterDescription
Service IDThe Y.1564 service identifier.

Values range from 1 to 8 and are not user editable.

Service nameName of the Y.1564 service.
Enable serviceEnable or disable the service for this Y.1564 test.
Policing testEnable or disable testing above the CIR:
  • If EIR < 20 % x CIR, Policing Rate = (125 % x CIR) + EIR
  • If EIR ≥ 20 % x CIR, Policing Rate = CIR + (125 % x EIR)
Step testEnables or disables running successive tests at a rate of 25% CIR, 50% CIR, 75% CIR, 100% CIR, and CIR+EIR.
AvailabilitySelectable check box to indicate availability.
Out-of-order percentageThis parameter can be enabled or disabled. When enabled, the Out of Order (OOO) frames/packets count is considered in the pass or fail of the network test.
Preserve DSCP and PCP VerificationWhen this option is enabled, the peer unit verifies that the DSCP/PCP values configured in the test traffic have not changed. If they have changed, the test will fail.

Note: Applies to one-way delay tests only.

Bandwidth (flow parameters)

ParameterDescription
CIRThe CIR value provided here can be interpreted as the maximum sustained information rate that the network has committed to transfer while meeting the performance level guaranteed in the Service Level Agreement (SLA).

The CIR and EIR values specified in the bandwidth profile are used by the Y.1564 tool to define the Configuration, Performance and Policing Tests to be executed.

EIRThe EIR value provided here can be interpreted as the maximum sustained information rate, over and above the CIR, at which traffic is carried though the network, if possible.
Frame Size TypeThe test will be performed with this type of frame size.
Packet SizeThe size of each frame for the test traffic.
User defineThe size of each user-defined packet for the test traffic.
Sequence of sizesFor the EMIX frame size type, the packet size values used in the test and the specific sequence in which they are sent.
Committed Burst SizeThe maximum number of kibibytes available for a burst of frames that are sent at the port's speed and remain CIR conformant. Range: 0 to 10,000 KiB.
Excess Burst SizeThis parameter is not currently used and is grayed out. This is for future implementation only.

The policing test will pass if IR-T ≤ CIR + EIR + M.

Where:

  • IR-T: Total Information Rate
  • CIR: Committed Information Rate
  • EIR: Excess Information Rate
  • M: M factor.
Default value: 1 Mbps
