Members
NOTE - In order to make fast progress, we are looking to keep the group size to a minimum and consisting as much as possible of TOSCA SME's.

Assumptions
Objectives
- Establish TOSCA as the "normative", supplier/operator neutral way to package and describe (model) network service and functions in ONAP.
- Enable template reuse and orchestration outcome consistency across ONAP related on-boarding, design, instantiation and operation activities.
- Identify TOSCA adoption barriers/gaps and recommend closure actions.
Tasks
- Template use...
- Define when and how TOSCA templates are used across on-boarding, design, instantiation and operation time
- Define template versioning strategy.
- New versions of VNFDs inside VNF packages to be on-boarded
- Support for multiple VNF template versions (e.g.SOL001) inside ONAP (transcoding)
- Identify template gaps and recommend closure actions.
- Network service and function lifecycle orchestration...
- Define end-to-end component interactions and dependencies required for TOSCA based orchestration activities across on-boarding, design, instantiation and operation time.
- Identify interaction gaps and recommend closure actions.
- Define how TOSCA templates are used in conjunction with emerging encoding and packaging alternatives.
- Recommendations...
- Architecture Subcommittee
- Modeling Subcommittee
- Projects
TOSCA Task Force - Dublin Recommendations
Personas & NS/NF Template Lifecycle (Draft)
| Gliffy | ||||||
|---|---|---|---|---|---|---|

To Do's
- Initial list of gaps - Fred (Verizon)
- Initial persona definitions - Michela (Ericsson)
- Stage definitions - Alex
- Gaps with respect to VNF requirements - Thinh (Nokia)
- Versions of TOSCA grammar to be supported by ONAP for on-boarding and/or internal use
Initial Gaps
Model for describing VNF Application Configuration Data
SOL001 has VNF configurable_properties data type but no prescriptive definition of use
Currently being used for setting VNF Day 0/1 configuration, e.g. self IP, NTP server, DNS server, EMS IP, …
VNF KPI/Indicators are not well described
Need description of KPIs/indicators exposed by the VNF and access method for each
VES may be a possible model
VNF Rules (Policies)
Need default policies based on above KPIs that can be used to drive various Life Cycle operations
Persona Definition
Service Provider: The entity providing a service
Consumers: The entity requiring and consuming a service
Different actors can be involved in providing a service :
Developers: . The developer may create additional artifacts/templates/blueprint to be used during the lifecycle of the service in addition to the ones provided by the vendors (e.g. create a new SO flow).
Operations: the operation team is responsible of the status changes of a service. It operates and monitor the service status.
According to ETSI SOL004, VNF package shall support a method for authenticity and integrity assurance. The VNF provider creates a zip file consisting of the CSAR file, signature and certificate files. Manifest file provides the integrity assurance of the VNF package. The VNF provider may optionally digitally sign some or all artifacts individually, in particular software images. The security aspects of the package and its contents will be covered during the onboarding phase by the operation team. Some vendor VNF Managers use the signatures to verify that the package artifacts haven't been modified so the original package artifacts need to be passed to the VNF Manager
Designers: It is responsible to design new artifacts to be used at run time (e.g a microservice blueprint, a service template, a clamp blueprints).
The role of the actors can be more specific per use case/stage.
Pre-onboarding
A pre-onboarding phase is not included in the NS/NF templace lifecycle above .
During the pre-onboarding phase/validation phase, TOSCA descriptor is validated according to the Validation Program based on VNF SDK tools. Today this is applicable to NF only, it could be applicable to NS too in the future. ONAP Reference: VNF Test Platform (VTP)
Use Case: VNF package validation
Actors: Vendor or Operator
Role: They both can run the test cases/test flows Different validation tools options are provided where both a vendor or an operator as a 3rf parties lab testing can run test cases.
