Name of Use Case: Third Party Operational Domain Manager

Participants : Telstra

Description:

  • A standards-based approach that supports third party service management
    • Fixed Broadband Access Service from third party
    • Managed Network Service
    • Telco peers
    • Multiple Cloud Service Providers
    • Etc…
  • ONAP provides Operations Domain Management (ODM) and other complementary capabilities to ensure full automation of the E2E lifecycle management of the service
  • Services are exposed and consumable via Network as a Service (NaaS) which is an abstraction layer above the operational domains and exposes the services to BSS
  • Consistent way of consuming 3rd party services from Service Providers
  • LCM and assurance events are triggered by the 3rd party service, and remediation response are executed.
  • Substitutes multiple handovers between parties/teams and applications to enable zero touch automation

BUSINESS DRIVER 

This section describes Business Drivers for this Use Case.

Executive Summary - This use case will provide ONAP capability to be operational domain manager for third party services. Service providers will be able to use ONAP to provide end to end automation for composite or white labelled services which could be provided and managed by third parties. This use case will provide ONAP capability to support federated catalog and orchestration.

Business Impact - The use case provides a generic ability for seamlessly on-boarding partner domain catalog which can be leveraged by service providers using ONAP. Lack of this capability leads to manual creation of partner service catalogs which is time consuming and dependent on human intervention. With this capability, the partner catalogs will be available for placing orders for Partner Domain services very quickly. The future phase of this use case also plans to look at enhancing the operational domain manager capabilities for life cycle management and also managing assurance events  triggered by the third party service and execute remediation response.

Business Markets - 

  • Following can be potential candidates for Third Party (or Partner) Domains which can be managed by ONAP:

    1. National Broadband Network (NBN) [Ref: https://www.nbnco.com.au/] Fixed Broadband Service,
    2. Managed Network Service from Service Providers
    3. Telco peers
    4. Multiple Cloud Service Providers to support a hybrid cloud ecosystem of private and public clouds
    5. Etc.
  • This use case is also relevant to Single Operator environment (e.g. If an operator wants to move its catalog from test to production, it can use this import catalog capability to on board the catalog, without manually recreating it in the production ONAP instance.)
  • This will be very relevant for automation of digital services delivered via 5G Ecosystem (B2B2X Models)

Funding/Financial Impacts -

  • This use case capability, once developed, can be used by any service provider deploying and using ONAP.  
  • Third Party Domain manger will play a significant role in on-boarding partner domains in a uniform manner.
  • The Service Catalog of the Partner Domain will be made available to the Service Provider in few hours, consumable via an abstraction layer (NaaS in Telstra context). 
  • Once catalog is on-boarded ONAP can publish the Service details to BSS and it can be used for ordering Partner Domain services by the Service Provider.

All this will essentially bring down time to market significantly for partner services.

Organization Mgmt, Sales Strategies - There is no additional organizational management or sales strategies for this use case outside of a service providers "normal" ONAP deployment and its attendant organizational resources from a service provider.

PNF/VNF : Preference will be to use Fixed Broadband Access Service and associated network functions as reference for this use case. Clearwater IMS will be the backup option

Work Flows:

The use case is being divided into sub use cases in order to limit the scope of changes for E release.

Sub Use Case 1 (targeted for E Release)

Import Service Catalog

Submit Order

Interaction Flow

  • Third Party Catalog import
  • Publish Catalog
  • Submit an O2A order
  • Fulfill the order

This sequence diagram depicts external catalog sync into SDC followed by order request from BSS

The flow steps

Catalog Sync Summary

1 – External Third party domain exports it service catalog details to Telstra. Telstra orchestrator ONAP exposes TMF Open API 633 Service Catalog API via ONAP Ext API component. Third Party Domain leverages the API 633 to POST the Service Catalog payload.

POST nbi/api/v3/serviceSpecification

Request body –ONAP compatible Service CSAR / (json ??)

CSAR contents:

RFSS for Partner Domain Service

2 – ONAP Ext API updates SDC catalog by invoking internal SDC API

POST sdc/v2/catalog/services

3 – Ext API notifies Third party after successful update within ONAP

4 – Service Decomposition happens in SDC (any manual updates e.g. creating composite service)

SDC updates other ONAP components (which have registered with SDC DMaaP) with catalog details

5a – SO pulls SDC catalog details

5b – AAI pulls inventory details

Ext API also notifies northbound systems (BSS/NaaS) after successful import of the service catalog into ONAP.

5c - BSS retrieves catalog information from ONAP

Order Activation Summary

6 – BSS submit order using TMF 641 Service Ordering API, that is exposed by ONAP Ext API

7 – ONAP Ext API submits the request to ONAP SO

8 – ONAP SO decomposes the service and submits the request by invoking Ext API (This is similar to what is being proposed for CCVPN use case as well. This maintains that only Ext API interacts with outside world and other ONAP components do not)

9 – ONAP Ext API invokes the Third Party Ordering API

Sub Use Case 2 (planned for G release)

Automated VNF Life Cycle Management – to cater for change management, incident management and version/configuration management

Service Assurance enablement for Third Party Domains’ exposed services

Control Automation:

Following items for VNF LCM and Service Assurance for Third Party Domain are being considered for the next phase of the use case for F release

  • The service life cycle management action can trigger for:
    • CM: change management (capacity increase to meet scaling demands);
    • IM: incident management (problem identification and fix); and
    • VM: version/config. management (VNFs’ adaptation to topology/config changes during run time of the service)
  • Remediation actions are executed automatically using ONAP as ODM


Project Impact:

Projects impacted as part of sub use case 1

  • SDC
    • In order to import the Service Catalog, Service load will have to be sent to SDC from Ext API.
    • JSON representation of the Service load needs to be identified and agreed with SDC team
  • Ext API
    • TMF 633 POST needs to be implemented in Ext API
    • Invoking the Third party Ordering API

A&AI (change to A&AI will be analyzed as part of next phase of the use-case, for cross domain inventory management)

Work Commitment:

Telstra team will work on SDC and Ext API changes. We welcome partner contributions into this usecase.

The details of changes are being discussed with the PTLs
