Casablanca feature proposal Ludovic Robert

1/ Add notification for serviceOrder API

Relevance : ***

Complexity : Easy

Allow BSS (or any other) system to receive order/OrderItem update. BSS (or any other system) will not have to pool. We can allow several distinct notification (Nice to have: let subscriber specify notification contains). Minimum is to provide ServiceOrderStateChangeNotifications etc to HUB subscriber. After if we’re able to get a notification from SO it will be perfect but initial requirement is only at external API northbound

Prerequisite : nothing for basic deliver…SO notifications to have high performance (without SO notification, NBI will pool SO as of today)

Notifications related to ServiceOrder: - ServiceOrderCreationNotification - ServiceOrderAttributeValueChangeNotification - ServiceOrderStateChangeNotification - ServiceOrderInformationRequiredNotification - ServiceOrderRemoveNotification

2/update ServiceOrder to manage Service modification request UC

Relevance : ***

Complexity : Average to High depending on SO capability to handle service modification

This will allow BSS system to trigger service modification request. By modification we mean: characteristic value change, status change (other ?). Minimum could be to handle modification that can be managed in SO with a Delete Service and then Add service (this is a change up to nbi but remove/add down to nbi). This is not service order modification butt service modification on existing service instance in the inventory (new service order with action change)

Prerequisite : could require SO upgrade – Check if some use case can be handle by NBI only (triggering add/remove in SO) ?

Possibly related to CC VPN use case, explore other use cases

3/Add notification for serviceInventory API

Relevance : **

Complexity : Easy

Allow BSS (or any other) system to receive service state update.

Prerequisite : It requires to have a notification from AAI because NBI will not pool AAI

4/Add notification for serviceCatalog API

Relevance : **

Complexity : Easy

Allow BSS catalog function to receive service catalog notification as serviceSpec status change or characteristic change (new value in an enum list for example). Could be interesting to track these serviceSpec update to update accordingly productSpec

Prerequisite : It requires to have a notification from SDC because NBI will not pool AAI

5/Improve ServiceCatalog API for characteristic (Adrian suggestion)

Relevance : **

Complexity: ***

Expose from NBI json (or other format) file describing the serviceSpec characteristic (same type of file we can retrieve on MEF Git Hub to describe an UNISpec for example)

Prerequisite : Need SDC improvements

Convert YAML in CSAR to ONAP wide consistent JSON schema for Service Characteristic Input parameters and provide across the ServiceCatalog API

6/Improve ServiceInventory API

Relevance : ***

Complexity: ?

As of now we retrieve very few information from AAI – Perhaps digging more in the instantiated VNF or VF could allow us to have more information as service state or serviceCharacteristic for example.

Adrian has also some thoughts on that.

Prerequisite : Need AAI expertise

Need enhancement to AAI UI to see more topology details across API

7/Integrate External API/NBI within ONAP MSB

Relevance : **

Complexity: ?

Prerequisite : Work with MSB team

• May need to consider how External API agent functionality can be decoupled from MSB

• • 8/ Build End-to-End Use Case 

    Relevance : **

    Complexity: ?

    Prerequisite : 

  • Showcase External API from a complete Service Lifecycle perspective. Apply ONAP Use Cases.
• All agree that these 8 items are to be included into scope for Casablanca

...

• Casablanca Proposal: see: <link>
• API Logging possibly using a Log Processor like Apache Nifi
• Allows temporal flow analysis of API calls
• Looking for interest in contributing to this activity
• Logging message structure with JSON schema
• Demo next week
• Agree to add to Casablanca scope
• Share with Architecture Sub-committee (Jack and  Parviz)

...

• Casablanca Proposal, see: link
• Extend ExtAPI scope to include "southbound APIs" to External SDN Controller, Edge Orchestrators, Domain Orchestrators, Domain Controllers (also Legacy OSS)
• Need to explore relationship with MEF Presto NRP based on ONF TAPI
• Continue discussion next week

...

• Example Modify CIR for E-Access Service instantiated in a Partner Domain
• Flows showing how Interlude works for the Elastic E-Access service
• Potential Casablanca definition

...

• Cover registration, "visual range" of service as external 

...

• HOMEWORK: Which APIs have business impact; Put together PPT on proposed Casablanca API functionality.
• Use Cases for Interlude; End to end flows 
• Code to parse YAML from Service Catalog. Work with SDC on TOSCA toolset. Parse YAML within SDC once and create inputs once Service Definition is finalized.
• Service Qualification / Servicability (pre-order) (is capacity and topology available supporting the specific set of service parameters; do policies permit instantiation, mapping of Service requirements to capabilities provided by the platform; checking against of service constraints and characteristics from Service catalog (or via catalog exposure to BSS), Service compatibility with other services instantiated within the customer's service group )
• License Accounting
• A&AI Customer (Possible removal of customer info from ONAP)
• Enhancements for complex input types (transition from name-value pair to JSON structures-blob ) (e.g., MEF Bandwidth Profiles, L2 Connectivity as a Use Case)

...

• Sync up with A&AI on JIRA issues (Jenny Huang; Ludovic Robert) Next time
• Document API style used for External API at Legato interface reference point 
• Casablanca use cases for External API
• Modeling of external facing APIs for ONAP and other ONAP projects (e.g., CLI)
• Alignment on API styles for ONAP external APIs
• Slide updates for MEF meeting on External API and Legato  (Wednesday Morning) Andy Mayer; Ludovic Robert; Bithika; Mehmet Toy; Abinash Vishwakarma; mark gibson; Neil Thayer

• Proposal for Casablanca Manoj Nair
  
  • Presented proposal for Casablanca for hybrid service orchestration
    • Support for TMF 640 (or TMF 641); and  TAPI 2.0 and SOL002 for Customer Configuration to Partner Domains (Interlude)
    • Discussion: 
      • Could TMF 641 be used instead of TMF 640
      • Interactions with Partner Domain (Interlude) should be at Service Level not the Resource Level
      • Need to define flows based CCVPN use case to define function interactions and Service Level information
      • Relationship to ONAP Service Information Modeling effort
• Next Time:
  • Additional Casablanca Proposals
  • Proposal for Casablanca Manoj Nair
  • Interlude discussion Mehmet 

Last time

• R3+ Interlude discussion Mehmet Toy
  • Elastic EVC use case impacts on Legato and Interlude

  • Action: Andy Mayer to send Mehmet invite to modeling discussion
  • Explore possible inclusion of future ONAP use case for Elastic Connectivity Service Mehmet Toy, Andy Mayer, Parviz Yegani
  • Relationship with IETF L2 & L3 SM?
• Need for End to End use case within the ONAP Context  Mehmet Toy; Andy Mayer (review with arch team)
  • ACTION: Recommend end-to-end interactions based on LSO Operational Threads  Mehmet Toy; mark gibson; Jack Pugaczewski;  Andy Mayer (review with arch team); Include scope of Presto wrt ONAP
  • ACTION: Possible application of External API at PRESTO with SDNC interactions with domain controllers (VOLTE use case) Possibly Jack Pugaczewski? 
  • Could possibly be part of R3 Casablanca scope

Working:

• Continue ExtAPI Design for Beijing Ludovic Robert
  • Update: Removed VNF creation from scope and notification feature from scope
  • Utilizing the ExternalAPI/NBI repo for Beijing code
  • Making good progress for 29 March milestone
  • Documentation
  • Repo committs
  • ACTION: Need to schedule meetings with SDC, SO, and A&AI to discuss API mapping; Also Run-time Catalog.
  • ISSUE: Is SDC Providing CSAR from Catalog API? Could SDC provide a simple service view with input parameters of the service?
  • ISSUE: Does SO require customer on instantiation requests? Is A&AI really keeping Customer (or Consumer) information?
• Begin Interlude Use Case discussion
• Dana Bobko will present an API Versioning proposal (NEXT WEEK )
