DRAFT PROPOSAL FOR COMMENTS

The content of this template is expected to be fill out for M1 Release Planning Milestone.

Overview

Scope

What is this release trying to address?

The Beijing Release will be focusing on Platform Maturity as a priority. Additional LCM actions will be added to the scope of APIs supported. These additional LCM actions have already been developed and validated by AT&T and will be contributed to ONAP. 

More specifically, APPC will focus on the following areas in Beijing.

• Remove references and use of openecomp and replace  with onap 
• Address Platform Maturity requirements to the extent possible to comply with minimum requirements requested for Beijing.
• Support AAF (Authentication and Authorization Framework) for API access
  • Dependency on AAF project to provide feature (AAF-91) to enable AAF security on the web server level (jetty level).
• Upgrade ODL version to Nitrogen (driven by CCSDK dependency)
• Replace MySQL with MariaDB (driven by SDNC dependency)
• Increase Code Coverage to 50%
• Provide support for the following new LCM actions:
  • Following Actions in support of In-place software upgrade
    • QuiesceTraffic
    • ResumeTraffic
    • UpgradeSoftware
    • UpgradePreCheck
    • UpgradePostCheck
    • UpgradeBackup
    • UpgradeBackout
  • Additional LCM actions including:
    • ActionCancel
    • ActionStatus
    • AttachVolume
    • DetachVolume
• Contribute CDT Tool - an APP-C Design Tool enabling VNF owners to create templates and other artifacts used by APP-C Configure actions (used to apply a post-instantiation configuration) as well as other life cycle commands.
• Documentation updates for Beijing

Use Cases

Describe the use case this release is targeted for (better if reference to customer use case).

The use cases supported in Amsterdam release will continue to be supported as part of regression assuming all other components do likewise.

At this writing, APPC will not be contributing to any new use cases .

The Change Management use case is working with SDNC for an L3 device firmware upgrade; however, note that APPC will be adding capability to do an in-place software upgrade for a VNF)

Discussions are still taking place around the manual Scaling use case; however, no definitive outcome at this stage due to lack of resources.

Minimum Viable Product

Describe the MVP for this release.

• Northbound REST Layer - This layer is responsible for interfacing with APPC clients such as SO, SDC, etc... via YANG-based API vis REST HTTP, message bus (DMaaP) and exposes APPC APIs enabling performance of lifecycle operations.
• APPC Provider - responsible for validating the YANG Remote Processing Call (RPC) input and for rejected when malformed. Upon successful validation, the APPC Provider call the Dispatcher to continue the request processing.
• APPC Dispatcher - responsible for processing requests received by the Request Handler and, if valid, selects the correct Directed Graph (DG) workflow for execution. Upon DG execution completion, the Dispatcher informs the initiator of results of the execution and updated data in AAI.
• Service Logic Interpreter (SLI) - responsible for executing the DGs. The Dispatcher invokes the SLI framework to execute a specific DG based on the input action. The SLI executes the DG and the sub-DG and returns a success or failure response to the Dispatcher.
• AAI Interface - APPC uses AAI as a source of VNF data, including status, topology, and operational data. It also makes updates to AAI as a result of a lifecycle operation.
• Southbound Layer - plugin architecture, uses several adapters to communicate to VNFs
  • Restcont adaptor
  • Netconf
  • SSH (XML/CLI)
  • IaaS - Interface as a Service, which is part of the OpenDaylight platform, which provides the framework for APPC
  • Chef
  • Ansible
• Components that operate across all the APPC modules, including Logging, Security, KPI Service, data access service for access to internal DB (MySQL in R1, MariaDB planned in R2)

Functionalities

List the functionalities that this release is committing to deliver by providing a link to JIRA Epics and Stories. In the JIRA Priority field, specify the priority (either High, Medium, Low). The priority will be used in case de-scoping is required. Don't assign High priority to all functionalities.

Epics

Stories

Longer term roadmap

Indicate at a high level the longer term roadmap. This is to put things into the big perspective.

The long term road map is to achieve all the goals outlined in the approved project proposal; to be fully model and standards driven, be agnostics and make no assumptions about the network. Support configuration and lifecyle management of VNF/VNFC in a generic fashion so that on-boarding any new VNF/VNFC is just a matter of configuration and data. Longer term items include:

• Automated scaling
• Support beyond Openstack and move to an adaptor type architecture so that multiple types of clouds can be supported with little effort
• Align to the controller architecture proposed as part of ONAP by the architecture team.

Release Deliverables

Indicate the outcome (Executable, Source Code, Library, API description, Tool, Documentation, Release Note...) of this release.

Sub-Components

List all sub-components part of this release.
Activities related to sub-components must be in sync with the overall release.

Sub-components are repositories and are consolidated in a single centralized place. Edit the Release Components name for your project in the centralized page.

ONAP Dependencies

List the other ONAP projects you depend on.

APPC depends on the the following components as part of the general ONAP architecture:

• SDC: Rest based interface exposed by SDC. APPC receives notifications from SDC on VNF information. SDC team provides an SDC Listener, which is used by APPC.
• AAI: APPC retrieves and updates VNF data from/to AAI.
• DMaaP: Message bus for communication with other components in the solution (SDC, DCAE, MSO, Portal, OOM)
• CCSDK - APPC currently gets ODL & DB package from CCSDK; CCSDK and APPC currently must align on ODL version. 
• AAF - AAF is used for authentication of APIs
• MultiVIM - APPC can access Openstack via MultiVIM or CPD-PAL. MultiVIM is optional for APPC at this stage.

For the Beijing release, APPC has dependencies on the following three projects for specific deliverables:

• CCSDK - - Nitrogen ODL docker
• SDNC -  MariaDB docker
• AAF - feature AAF-91 - needed to address API level security

Architecture

High level architecture diagram

At that stage within the Release, the team is expected to provide more Architecture details describing how the functional modules are interacting.

Indicate where your project fit within the ONAP Archiecture diagram.

Block and sequence diagrams showing relation within the project as well as relation with external components are expected.

Anyone reading this section should have a good understanding of all the interacting modules.

For details on the APPC architecture, refer to the APPC User Guide.
