  • 1.  Passing resource number from TMF639 to TMF641

    Posted Feb 09, 2021 08:16
    Hi,

    We @MTS, are trying to align our platform APIs based on TMF633, TMF634, TMF638, TMF639 for our business use cases.

    When selling the product, we gave the physical device (physical resource saved in TMF639) to the customer. Next, we order the service (TMF641) and want to pass the serial number (or generated resource ID from TMF639) of the issued device in the serviceOrder. This is because we want to activate the service on exactly this device. To transmit a number, we have to use the serviceCharacteristics (which is the only one that has a attribute "@value" in TMF641), but it seems that this is not the most appropriate place, since the serial number of the issued device does not look like the characteristics of the service. This value is more similar to the associated activation parameters of the service, rather than its characteristics.

    How is it more correct to pass such values?

    Hi Victor
    The Service entity has an array attribute supportingResource of type Resource. You could use this to point to the resource entity(ies) that you had created in the inventory.
    Does this make sense?
    Hope it helps

    Thanks you, Jonathan. That makes sense, sure!

    But it leads to ordering instances of RFSS. We see following comment in JSON on supportingResource :
    >Note: only Service of type RFS can be associated with Resources 

    Does it mean that TMF641 is for ordering of RFSS along with CFSS? 
    Previously I believed that the RFSS should be under CFSS in TMF633 and the serviceOrder contains only references to CFSS.

    Hi Victor
    As an OSS novice, I don't see why 641 couldn't be used for ordering RFS as well as CFS.
    But I'll defer to the experts, tagging them here: @Johanne Mayer @Ludovic Robert @Vance Shipley​​​​

    Hello,
    Within Orange we use the ServiceOrder (TMF641) for CFS but also for RFS. We consider RFS as service.
    We expose a TMF641 (CFS granularity) at the 'northbound' of the Product system. The ServiceOrderManagement system receive this CFS-Based service order and compute the RFS to be applied. If the 'resource domain' in charge of this delivery could manage the RFS itself we send it via a TMF641 (RFS granularity). This is our 'preferred' way of interact because it allows decoupling between the SOM and resource domain.

    This is probably a good topic to be discussed in ODA and in particular for E2E process....I'm sure we'll have distinct fair perspectives.

    Hope it helps

    Thank you for your reply!

    I just want to eliminate or understand the contradiction in  TMF641_Service_Ordering_Management_API_User_Guide_v4.0.1

    I see comment for supportingResource

    supportingResource

    A list of resource references (ResourceRef [*]). A list of supporting resources (SupportingResource [*]).Note: only Service of type RFS can be associated with Resources.


    but there is an example below:

    {
        ...
        "serviceOrderItem": [{
                "id": "1",
                "action": "modify",
                "state": "acknowledged",
                "service": {
                    "id": "456",
                    "@type": "Service",
                    "href": "http://serverlocation:port/serviceInventoryManagement/v4/service/456",
                    "state": "active",
                    "serviceType": "CFS",
                    "serviceCharacteristic": [{
                            "id": "452-gh6",
                            "name": "InputPort",
                            "valueType": "string",
                            "value": "456/7"
                        }
                    ],
                    "supportingResource": [{
                            "id": "3456_DFG5-H690",
                            "href": "http://serverlocation:port/resourceInventoryManagement/v4/resource/3456_DFG5-H690",
                            "@referredType": "CloudResource"
                        }
                    ]
                },
                "@type": "ServiceOrderItem"
            }
        ]
    }
    ​

    And in this JSON we see that supportingResource are applied to CFSS, not RFSS, in attribute "serviceType": "CFS"

    My questions are:
    1) can we use supportingResource in CFS ?
    2) can we order RFSS in serviceOrders  OR  they must be decomposed from CFSS on the SOM side?

    Indeed a good topic to discuss.

    There are indeed different approaches possible. We tend to use TMF641 only for CFS. The ServiceOrderManagement is then responsible for updating CFS in the ServiceInventory. It will then do service design: this is the decomposition of the CFS in the required RFS. which will also be stored in the ServiceInventory.
    In the reservation phase the ServiceOrdermanagement will update the RFS with the supportingResources (devices, but also IP addresses, phone numbers, VLAN, ...)
    When all supportingResources are available the RFS can be activated by calling the TMF640 Service Activation & Configuration for a single RFS.
