Overview of SDNC Actor
-#############################
+######################
+ONAP Policy Framework enables SDNC as one of the supported actors.
+SDNC uses a REST-based interface, and supports the following operations:
+*BandwidthOnDemand*, *Reroute*.
+
+Each operation supported by the actor is associated with its own java class, which is
+responsible for populating the request structure appropriately. The operation-specific
+classes are all derived from the *SdncOperation* class, which is, itself, derived from
+*HttpOperation*. Each operation class implements its own *makeRequest()* method to
+construct a request appropriate to the operation.
+
+
+Request
+#######
+
+A number of nested structures are populated within the request. The following table
+lists the contents of some of the fields that appear within these structures.
+
++----------------------------------+---------+----------------------------------------------------------------------+
+| Field Name | Type | Description |
++----------------------------------+---------+----------------------------------------------------------------------+
++----------------------------------+---------+----------------------------------------------------------------------+
+| top level: | | |
++----------------------------------+---------+----------------------------------------------------------------------+
+| *requestId* | string | Inserted by Policy. Maps to the UUID sent by DCAE i.e. the ID |
+| | | used throughout the closed loop lifecycle to identify a request. |
++----------------------------------+---------+----------------------------------------------------------------------+
++----------------------------------+---------+----------------------------------------------------------------------+
+| sdnc-request-header: | | |
++----------------------------------+---------+----------------------------------------------------------------------+
+| *svc-action* | string | Set by Policy, based on the operation. |
++----------------------------------+---------+----------------------------------------------------------------------+
+| *svc-request-id* | string | Generated by Policy. Is a UUID. |
++----------------------------------+---------+----------------------------------------------------------------------+
++----------------------------------+---------+----------------------------------------------------------------------+
+| request-information: | | |
++----------------------------------+---------+----------------------------------------------------------------------+
+| *request-action* | string | Set by Policy, based on the operation. |
++----------------------------------+---------+----------------------------------------------------------------------+
++----------------------------------+---------+----------------------------------------------------------------------+
+| network-information: | | Applicable to *Reroute*. |
++----------------------------------+---------+----------------------------------------------------------------------+
+| *network-id* | string | Set by Policy, using the |
+| | | "network-information.network-id" property |
+| | | found within the enrichment data provided by DCAE |
+| | | with the ONSET event. |
++----------------------------------+---------+----------------------------------------------------------------------+
++----------------------------------+---------+----------------------------------------------------------------------+
+| vnf-information: | | Applicable to *BandwidthOnDemand*. |
++----------------------------------+---------+----------------------------------------------------------------------+
+| *vnf-id* | string | Set by Policy, using the |
+| | | "vnfId" property |
+| | | found within the enrichment data provided by DCAE |
+| | | with the ONSET event. |
++----------------------------------+---------+----------------------------------------------------------------------+
++----------------------------------+---------+----------------------------------------------------------------------+
+| vf-module-input-parameters: | | Applicable to *BandwidthOnDemand*. |
++----------------------------------+---------+----------------------------------------------------------------------+
+| *param[0]* | string | Set by Policy, using the |
+| | | "bandwidth" property |
+| | | found within the enrichment data provided by DCAE |
+| | | with the ONSET event. |
++----------------------------------+---------+----------------------------------------------------------------------+
+| *param[1]* | string | Set by Policy, using the |
+| | | "bandwidth-change-time" property |
+| | | found within the enrichment data provided by DCAE |
+| | | with the ONSET event. |
++----------------------------------+---------+----------------------------------------------------------------------+
++----------------------------------+---------+----------------------------------------------------------------------+
+| vf-module-information: | | Applicable to *BandwidthOnDemand*. |
++----------------------------------+---------+----------------------------------------------------------------------+
+| *vf-module-id* | string | Set by Policy to "". |
++----------------------------------+---------+----------------------------------------------------------------------+

+
+Examples
+########
+
+Suppose the *ControlLoopOperationParams* were populated as follows:
+
+.. code-block:: bash
+
+ {
+ "actor": "SDNC",
+ "operation": "Reroute",
+ "context": {
+ "enrichment": {
+ "service-instance.service-instance-id": "c7c6a4aa-bb61-4a15-b831-ba1472dd4a65",
+ "network-information.network-id": "2246ebc9-9b9f-42d0-a5e4-0248324fb884"
+ }
+ }
+ }
+
+An example of a request constructed by the actor using the above parameters, sent to the
+SDNC REST server:
+
+.. code-block:: bash
+
+ {
+ "input": {
+ "sdnc-request-header": {
+ "svc-request-id": "2612653e-d946-423b-96d9-a8d5e8e39618",
+ "svc-action": "reoptimize"
+ },
+ "request-information": {
+ "request-action": "ReoptimizeSOTNInstance"
+ },
+ "service-information": {
+ "service-instance-id": "c7c6a4aa-bb61-4a15-b831-ba1472dd4a65"
+ },
+ "network-information": {
+ "network-id": "2246ebc9-9b9f-42d0-a5e4-0248324fb884"
+ }
+ }
+ }
+
+
+An example response received from the SDNC REST service:
+
+.. code-block:: bash
+
+ {
+ "output": {
+ "svc-request-id": "2612653e-d946-423b-96d9-a8d5e8e39618",
+ "response-code": "200",
+ "ack-final-indicator": "Y"
+ }
+ }
+
+
+Configuration of the SDNC Actor
+###############################
+
+The following table specifies the fields that should be provided to configure the SDNC
+actor.
+
+=============================== ==================== ==================================================================
+Field name type Description
+=============================== ==================== ==================================================================
+clientName string Name of the HTTP client to use to send the request to the
+ SDNC REST server.
+timeoutSec integer (optional) Maximum time, in seconds, to wait for a response to be received
+ from the REST server. Defaults to 90s.
+path string URI appended to the URL. This field only applies to individual
+ operations; it does not apply at the actor level. Note: the
+ *path* should not include a leading or trailing slash.
+=============================== ==================== ==================================================================
-This is a place-holder for the actor documentation.
+The individual operations are configured using these same field names. However, all
+of them, except the *path*, are optional, as they inherit their values from the
+corresponding actor-level fields.
