EPIC:

  1. SDN-C support BBS Usecase

Story:

  1. Depends on the Data Model definition to expose the API for the resource in SDN-C

  2. Develop the new DGs for the PNF configuration during the PnP and Nomadic ONT.

Tasks:

  1. Until the DM defined. (Both Design Time and Runtime)

Sub-UC1: Topology Discovery and Synchronization

CCSDK/SDNC-C Diagram

Flow Discription

1.User registers 3rd party controller information in ESR.

2. ESR triggers a 3rd party controller registration event to DMAAP

3. SDNC subscribes to the event and gets event ntification

4. SDNC queries topology from 3rd party Controller

5. SDNC decomposes and save topology to AAI

New Development

  1. Adapt existing DGs for sync topology to make a new BBS type, Each vendor will have a different API call and so we need a switch flag inside DG code to choose specific vendor sub-DG for the call

  2. Topology data model definition (optional, depends on whether we follow CCVPN model for topology). If new model is required, we need to adapt saving data to AAI DG.

  3. Make token authentication more generic

Sub-UC2: Service Creation and Activation

CCSDK/SDN-C Diagram

Flow Description

  1. Access SDN M&C notify ONT Register Event to DCAE

  2. DCAE Publishes an ONT Registration Event(pnf_registeration) to SO via DMaaP 

  3. SO Calls Generic Resource APIs of SDNC to trigger Access/Edge SDN M&C

  4. SDNC calls Access SDN M&C to configure RFS ONT

  5. SDNC calls Edge SDN M&C to configure IPAM and AAA

  6. Access SDN M&C notify RG Activated Event to DCAE

  7. DCAE Publishes an RG Activated Event to SO via DMaaP

New Development(Depends on the Modeling definition)

  1. Addition of new enumerations to generic-resource-api.yang for CreateAccessConnectivity, CreateInternetProfile.

  2. Addition of new resource to GenericResourceApiProvider.java (review it later)

  3. New DGs for the service creation

  4. Extending respective template for restapicall plugin in Network Adapters. We need to manually put the new template files for each vendor inside the SDN-C container

Sub-UC3: Nomadic ONT Service

CCSDK/SDN-C Diagram

Flow Description

1.Access SDN M&C notify ONT Register Event to DCAE
2.DCAE notify SO ONT registration
3.SO Calls Generic Resource APIs of SDNC to trigger Access SDN M&C
4.SDNC calls Access SDN M&C to delete old RFS ONT;SDNC calls Access SDN M&C to configure new RFS ONT
5.SDNC calls Edge SDN M&C to configure  AAA

New Development

  1. Addition of new enumerations to generic-resource-api.yang forDeleteAccessConnectivity, DeleteInternetProfile.

  2. Addition of new resource to GenericResourceApiProvider.java (review it later)

  3. New DGs for the service deletion

  4. Extending respective template for restapicall plugin in Network Adapters. We need to manually put the new template files for each vendor inside the SDN-C container

  5. Creation DGs/templates/additions are mentioned in the Sub-UC2.
