Policy Framework Project Proposal (5/11/17)

Project Name:

• Proposed name for the project: Policy Framework
• Proposed name for the repository: 
  • • • • • policy/api - Policy CRUD and PEP enforcement client code
          • policy/common - common shared modules
          • policy/pdp - Policy Decision Engines
          • policy/pap - Policy Administration (Backend)
          • policy/gui - Policy Administration GUI (Frontend)
          • policy/docker - Policy docker image

Project description:

The Policy subsystem of ONAP maintains, distributes, and operates on the set of rules that underlie ONAP’s control, orchestration, and management functions. Policy provides a centralized environment for the creation and management of easily-updatable conditional rules. It enables users to validate policies and rules, identify and resolve overlaps and conflicts, and derive additional policies where needed. Policies can support infrastructure, products and services, operation automation, and security. Users, who can be a variety of stakeholders such as network and service designers, operations engineers, and security experts, can easily create, change, and manage policy rules from the Policy Manager in the ONAP Portal.

Scope:

• Deliver points of interoperability within ONAP for VNF and network service On-boarding to capture policy/rule expressions, VNF vendor specific policies and network service policies.
  

  • The following areas are identified as places where Policy is currently supported and/or potentially needed in the ONAP Platform for R1 and beyond.

    	Current Seed Support	ONAP Project Dependencies	R1
    Placement	Yes	SNIRO	Continue support for SNIRO. Work to be done for Policy Driven VNF Orchestration via Alex Vul.
    Resource Allocation	No
    Remediation Actions (eg Scaling)	Yes – limited	SO A&AI	If SO and A&AI make API changes Policy will be impacted. Otherwise we anticipate being able to deliver this functionality.
    Compliance Checking (eg. Security)	No
    SLA	No
    Health	No
    Control Loops	Yes	APP-C SO VF-C A&AI	Will need to work with teams to support control loops. Will be impacted on any API changes to SO, APP-C and A&AI. Will need to develop VF-C interface.
    Platform Level Policies	No
    Governance for Users/Customers	No

  • Deliver where/how Policies are expressed
    • Policy Domain Specific Language(s) (DSL) - work with the Modeling project to define how policy expressions are captured
    • Policy Design GUI - work with SDC project to integrate the Policy Design GUI during VNF/Service design for capturing Policy Expressions
  • Deliver requirements for Policy Conflict Detection and mitigation
  • Deliver requirements for capturing vendor-embedded policy (Stretch)
• Deliver points of interoperability within ONAP in which captured policies are translated into enforceable actions/outcomes
  • Deliver architecture flow for identify how translation of DSL will work in the following ONAP scenarios:
    
    • Instantiation
    • Orchestration
    • Remediation
    • Controllers
    • Control Loop (Release 1)
      • DCAE Analytics, Collectors and Micro services: 
        • Design configuration policies and required models for the 3 Use Cases
      • CLAMP
        • Design operational policies for responding to Control Loop events for the 3 Use Cases
      • Controllers
        • Design, build and integrate required code to support 3 Use Cases for needed controller(s)
  • Identify how policy translation works
    
    • Design architecture for a common framework for the decision engines/languages used
    • The translation tools needing development
  • Identify the Enforcement points within ONAP to support the Use Cases
    • Common API design to support enforcement
  • Deliver points of interoperability for Day2Day Operations.
    • Identify architecture, flow and API's for how operations teams can update/deploy/un-deploy Policies
  • Deliver points of interoperability to support Adaptive Policy (Stretch)
    • Reverse planning, inference rules, machine learning
  • Deliver architecture and points of interoperability for Policy Distribution. The current seed code is limited in how policies are distributed, work needs to be done. (Stretch for R1)
    • Deliver architecture flow diagram on how Policy Decision Engines are deployed/un-deployed.
    • Define requirements as to which policies are supported in the various Decision Engines.
    • Deliver Swagger/DMaap API specification for PDP engines to communicate with PAP backend for policy distribution.

Architecture Alignment:

• How does this project fit into the rest of the ONAP Architecture?
  • Architecture Diagram

• • What other ONAP projects does this project depend on?
    • Modeling - provide input for Policy Expression
    • VNF SDK
    • SNIRO
    • SDC
    • ONAP Operations Manager
    • ONAP Extensibility
    • Control Loop
    • CLAMP
    • DCAE
    • Orchestration
    • Controllers
    • Basically every component in ONAP should be policy-enabled
• How does this align with external standards/specifications?
  • APIs/Interfaces
  • Information/data models
• Are there dependencies with other open source projects?
  • XACML (github.com/att/xacml)
  • Drools (drools.org)

Deliverables for R1

• PAP + Console (ONAP Portal app)
  • Policy CRUD and Deployment API
  • GUI for viewing and managing policies/PDP's
• Policy YAML SDK
  • For building Control Loop Operational Policies
• XACML PDP
• Drools PDP
• Nexus Repository
  • The repository for Drools Policy Rules and support code
• Database (MariaDB)
  • The repository for XACML Policies, templates, PDP Grouping and PDP Policy Deployment.
