Overview

Scope

What is this release trying to address?

CLAMP want to consolidate Casablanca achievement by

1. achieve the Casablanca S3P requirement for Casablanca in the limits the available resources permit.

2. making the support of new micro-service generic(no code development needed to support new mS)
   by implementing policy-models concept (together with DCAE-DS/SDC, Policy-engine).

Use Cases

The existing use cases are still going to be supported and additional use cases will be supported for the Casablanca Release (as defined by the Control loop sub committee: auto-scale out use case, BBS use case is a stretch goal depending on resources committed by interested companies)

Minimum Viable Product

The minimum viable product that we aim to reach within R4 is to have the CLAMP application Casablanca(R3) features at least running with, the new policy-model and blueprint template, as artifact exchanged between CLAMP and DCAE-D.

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.

Longer term Roadmap

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

The long term goal is to reach a common platform for managing control loops within ONAP :

CLAMP is a platform for designing and managing control loops.  It is used to design a closed loop, configure it with specific parameters for a particular network service, then deploying and undeploying it.  Once deployed, the user can also update the loop with new parameters during runtime, as well as suspending and restarting it.

It interacts with other systems to deploy and execute the closed loop.  For example, it pushes the control loop design to the SDC catalog, associating it with the VF resource.  It requests from DCAE the instantiation of microservices to manage the closed loop flow.  Further, it creates and updates multiple policies in the Policy Engine that define the closed loop flow.  

The ONAP CLAMP platform abstracts the details of these systems under the concept of a control loop model.  The design of a control loop and its management is represented by a workflow in which all relevant system interactions take place.  This is essential for a self-service model of creating and managing control loops, where no low-level user interaction with other components is required.

At a higher level, CLAMP is about supporting and managing the broad operational life cycle of VNFs/VMs and ultimately ONAP components itself. It will offer the ability to configure, test, deploy and update control loop automation - both closed and open. Automating these functions would represent a significant saving on operational costs compared to traditional methods.

Another Key long term goal is to provide a better user experience by having more flexibility to add mico-service without code development.

A Dashboard has been introduced to allow the user to get a quick overview of the status of running control loops.

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.

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.

Architecture

• Below we show how the CLAMP application fits into ONAP.  The red figure below shows the CLAMP application components.  There is a design portion and an operations component, which are both deployed within ONAP portal.

Open

•CLAMP is separated in 3 areas, which are currently (in seed code) both supported by a single application:

1. Design Time(Cockpit/UI to Configure the received templates)

2.  

   1.  SDC will distribute a CSAR, for a service, the part of the CSAR that CLAMP will use are:

      1.   the Control Loop flow Templates(e.g: blueprint) are defined in DCAE-D(sub-component of SDC) and distributed to CLAMP by SDC. The templates format is TOSCA. The blueprint is also pushed, by SDC, to DCAE platform orchestration engine.

      2. The policy-models defining the DCAE µS used inside the blueprint. note that policy-engine will also receive this SDC distribution and so should be also aware of those policy-models.

   2. policies (configuration and operational policies) are pushed/provisioned towards the Policy Component of ONAP. (those policies will be triggered by DCAE during Closed Loop operations).

      1. The DCAE team needs to provide models to Policy team in order for the Configuration policy to be built. 

3. Run time(DCAE-Policy, grabbing events and triggering policies based actions)

   1. the triggering to deploy(and then effectively start the closed loop)  a blueprint will be manual (via CLAMP cockpit) an automatic deployment based on an event will come in future release.

   2. The CLAMP cockpit will support the following action at runtime:

      1. start (start the provisioned Closed Loop on DCAE)

      2. stop (stop a provisioned Closed loop on DCAE)

4. Dashboard (ELK based)

   1. CLAMP also provides (as a separate components) an ELK stack (with specific configurations for the elk components) that listen to Control Loop events published on DMAAP on specific dmaap topics. 

CLAMP will thus control the typical following control loop flow within ONAP :

Platform Maturity

Refering to CII Badging Security Program and Platform Maturity Requirements, fill out the table below by indicating the actual level , the targeted level for the current release and the evidences on how you plan to achieve the targeted level.

API Incoming Dependencies

List the API this release is expecting from other ONAP component(s) releases.
Prior to Release Planning review, Team Leads must agreed on the date by which the API will be fully defined. The API Delivery date must not be later than the release API Freeze date.

Prior to the delivery date, it is a good practice to organize an API review with the API consumers.

API Outgoing Dependencies

API this release of CLAMP is delivering to other ONAP Component(s) releases.
