Feature Description
The SMF extends support to the Geo Redundant (GR) version of the Cisco Common Data Layer (CDL). When the primary CDL endpoint fails, the SMF attempts the same operation on the next highly rated secondary endpoint thus providing a non-disrupted N7 or Diameter message handling. If the next rated endpoint is unavailable, then the SMF reattempts the operation on the subsequent endpoint that has the highest rating and so on.
In case of specific errors or failures from CDL to SMF, the retry mechanism is used for the Create, Find, and Delete requests as well along with the earlier supported Update requests. The number of retries are as per the SLA.
When the SMF receives the successful response during the retries, then the retries are stopped and the response is sent to the application.
