Debugging failure of a service validation test
The present disclosure generally discloses a testing capability related to service testing in a communication network. The testing capability may be configured to support debugging of failures identified during service validation testing of a service in a communication network. The testing capability may be configured to support debugging of failures (e.g., transmission failures or the like) associated with a failed service validation test (e.g., a transmission verification test or the like). The testing capability may be configured to support debugging of failures identified during service validation testing of an Ethernet service. The testing capability may be configured to support debugging of failures (e.g., frame loss or the like) identified during service validation testing of an Ethernet service where the service validation testing of the Ethernet service is performed based on International Telecommunication Union (ITU)—Standardization (ITU-T) Y.1564, which is an Ethernet-based service activation test methodology.

receive, by the first device from the second device, the test traffic sent from the first device toward the second device for performing the service validation test.
9. The apparatus of claim 1 , wherein the first device comprises a test headend for the service validation test and the second device comprises a test loopback for the service validation test.
10. The apparatus of claim 1 , wherein the service comprises an Ethernet service, wherein the service validation test comprises an ITU-T Y.1564 test.
11. A method configured to support a service validation test for validating a service between a first device and a second device, the method comprising:
sending, from the first device toward the second device before initiation of the service validation test, a first statistics request message configured to request statistics from the second device; and
sending, from the first device toward the second device after completion of the service validation test, a second statistics request message configured to request statistics from the second device.
12. An apparatus configured to support a service validation test for validating a service between a first device and a second device, the apparatus comprising:
a processor and a memory communicatively connected to the processor, the processor configured to:
receive, at the first device from the second device before initiation of the service validation test, a first statistics request message configured to request statistics from the first device; and
receive, at the first device from the second device after completion of the service validation test, a second statistics request message configured to request statistics from the first device.
13. The apparatus of claim 12 , wherein the processor is configured to:
collect, at the first device based on the first statistics request message, a first set of statistics of the first device; and
send, from the first device toward the second device, a first statistics response message comprising the first set of statistics of the first device.
14. The apparatus of claim 12 , wherein the processor is configured to:
collect, at the first device based on the second statistics request message, a second set of statistics of the first device; and
send, from the first device toward the second device, a second statistics response message comprising the second set of statistics of the first device.
15. The apparatus of claim 12 , wherein the processor is configured to:
send, from the first device toward the second device based on the first statistics request message, a first statistics response message comprising a first set of statistics of the first device; and
send, from the first device toward the second device based on the second statistics request message, a second statistics response message comprising a second set of statistics of the first device.
16. The apparatus of claim 15 , wherein the first set of statistics of the first device comprises a first set of loopback debug statistics, wherein the second set of statistics of the first device comprises a second set of loopback debug statistics.
17. The apparatus of claim 12 , wherein the processor is configured to:
receive, at the first device from the second device, test traffic sent by the second device for performing the service validation test; and
send the test traffic from the first device toward the second device based on loopback of the test traffic by the first device.
