Success is defined as:

  1. TBD - documentation created ? test suites defined ? test suites executed ?
  2. TBD
  3. TBD

To-Do (In General)

This is a comprehensive list of work that can be done. A subset of the list below will go into  Baldy (and will be saved in the release notes for Baldy).

A: To be included in Baldy Release.

B: Nice to include in Baldy Release.

C: Low Priority for Baldy Release.

Comments
0A: ms RM cleanup (ch content complete 80%, issue closure)

1
  • B: 1.x Various: May need to be rationalized w/ new Tech Steering document

  • A: 1.9 Roadmap: This section needs perpetual maintenance (strongly consider moving the roadmap out of the RM, altogether)

  • A: RA Compliance/traceability methodology 

  • A: Still needs a crisp executive summary identifying the problem statement, and the two key methodologies employed to address them (VNF Abstraction and a common NFVI)


RM-Ch01 - Intro

  • A: RA Compliance/traceability methodology 
    • Needs to be Chapter 8 content (move to)
2
  • B: Needs a community aligned list of workloads the platform is intended to support and their priority, which can then be used as a basis for resource allocation and for weighting “suggestions” (notably “The public cloud does it this way, so we should too.”; understood, but we need an objective basis. Right now, it becomes a subjective debate)
  • A: Align and execute on Prague proposal to park the Compute Intensive flavor, and supplement it by removing "over-subscription?" from the Basic flavour
  • C: Flesh out quantitative details about supported workloads. (nice to have)

RM-Ch02 - VNF Requirements & Analysis
3
  • A: Needs tighter coupling w/ Container paradigm (i.e. decoupling from VM-based VNF)
    • flavours for example might not be applicable to containers(CPU and memory, disc we want to find a way for containers) - possibly Ch04
    • harmonisation of template in Model.
  • C: Needs a general review. Given the experience we’ve gained, can be made more succinct and more usable by a VNF developer
  • C: Need to clearly explain slicing (and contrast to Tenant) from CNTT perspective
  • B: Template attributes should be vetted w/ underlying capabilities, rationalized for duplication (i.e. CNTT value add, vs. what’s already in HEAT) and expanded to integrate Container paradigms
  • B: Data Model - Create actual schema(s) and data model(s) for CNTT-specific information (potentially in an appendix)
  • A: ms Shared w/ RM-Ch4: Need to define virtual networking strategy and related attributes/parameters (workload level)

RM-Ch03 - Modelling

Pankaj Goyal Flavours/Flavors are not mentioned in RM Ch03. The term "virtual resource" is used and that includes resources that result from both hardware (server) and Operating System virtualisation. Typically, VNFs and CNFs are  mentioned together; there is an exception that should be corrected.


4
  • A: Integrate more Container paradigms/support
  • C: ms Flesh out Generic Fabric Model (Fabric, Underlay and Overlay level (i.e. Infra, not workload)
  • C: Research and enhance storage performance extensions using performance per unit of storage model (i.e. IOPs/GB)
  • A) Hardware Profiles and Performance.
    • Objectives/
    • Guidelines
    • What level of granularity.
    • Validation/Auditing.
    • Proposals or white paper on how we plan to achieve deterministic performance from the reference model w/o having to specify hardware to down to a very granular level (e.g. w/o SKUs, clock speeds, etc.)
  • A: Clarify diagrams and language around T-Shirts, Flavors and IT relationships
  • A: ms Policies for Non-Conforming Technologies // assumes supporting frameworks are ratified
    • SRIOV policy
    • SmartNIC policy*
    • Live Migration policy
    • *includes Tomas’ concept of driving SmartNIC industry to standard, cloud-friendly ABI
  • A: Shared w/ RM-Ch3: Need to define virtual networking strategy and related attributes/parameters (workload level).
    • 4.2.2: need to consider aggregate network bandwidth instead of per Interface bandwidth.
  • TBD: VNF Evolution / VNF Profile Generations
  • TBD: Simplify VNF Profile Naming

RM-Ch04 - Infrastructure Capabilities, Measurements and Catalogue






Pankaj Goyal suggest that the White Paper be not priority A.

Generic Fabric Model → Focus on terminology for Baldy.

5
  • A: Integrate cloud native concepts w/ sw profile (i.e. how abstraction and workload portability is maintained)
  • A: Update s/w profile, pending parking of Compute Intensive IT
    • Rationalize s/w profile to IT mapping after removal of third IT
    • Audit chapter alignment w/ RM-Ch4
  • A: Incorporate VNF Profile Generations/Evolution (once ratified), designing and describing linkage/relationship to h/w profiles

RM-Ch05 - Feature set and Requirements from Infrastructure
6
  • B: Flesh out initial Enabler Services

RM-Ch06 - External Interfaces (APIs and Interfaces)
7
  • A: ms Worthy of review by SMEs for suggestions of areas to incorporate and/or refine
19 Feb 2020

RM-Ch07 - Security

Added Security Requirements PR#1118

8
  • Cleanup to Ch08
    • A: Generic  qualification model (i.e. NFVI and VNF)
      • Badging types (requirements in RC)
      • Methodology to support N-3 VNF Rls Profiles
    • A: Overview of badging methodology
      • Base-lining testbed before VNF qualification
      • VNF testing without prior knowledge
      • Plumbing testbed for supplier testing of VNF functionality, after VNF badging.
    • A: ms Overview of novel VNF-related concepts
      • Reference VNF (aka Golden VNF)
      • NFVI characterization, and correction coefficients for normalizing performance
    • A: What is out of scope for CNTT (e.g., VNF functional testing, performance, scalability, HA, etc.)

RM-Ch08 - Compliance, Verification, and Certification

Should the RM content be VNF/CNF agnostic?


9
  • C: Create Generic Installer Model

RM-Ch09 - Infrastructure Operations and Lifecycle Management
A
  • C: Needs a strategy/purpose review and new commitment from original or new contributors to continue on it.

1A: RI-1 cleanup (ch content complete 80%, issue closure)

2C: Resolve Continuous Software Deployment Errors
(MikeF add) - Not clear what that is. → MikeF:  Automatic deployment of OpenStack via the CICD Pipeline using AirShip fails.  Manual intervention is needed to resolve issues with erroneous port 80 references, incorrect NOVA versions, and end-point URLs which do not work.  (to name a few).  
3C: Document & Perform Repeatable CICD Deployment
(MikeF add) - some of it need to be documented in cookbook and some of it needs to be taken care of by OPNFV.
4A: Document how to Perform Repeatable Compliance Validations (post deployment)
(MikeF add) - some of it need to be documented in cookbook and some of it needs to be taken care of in OPNFV.

C: Close Gaps in Cookbook

[RC1 Ch9 - Snezka F2F] RC Cookbook Enhancements #945 

[RI1 Ch07] User Manual initial content #408

User-Execution

  • Common Failure codes, description, and resolutions
  • Test Framework Clean-Up Utility, Process, and Support Expectations

Process / Version Mgmt

  • Process for version control
  • Process for bug fixes and patches
  • Containers Tagged
  • Playbooks grab the tagged version

(MikeF add)
6C: Conduct Friendly Cookbook Trial

(MikeF add) - That is not for RI team to worry about.  → MikeF:  How/who will own this item as there needs to be a friendly trial of the cookbook with feedback/improvement?  This is about lab procurement, h/w and s/w validations, software installs, etc.  All pertaining to RI WS. 

Rabi: Michael Fix (AT&T) i will send you an invite to the weekly adoption meeting where we are getting those vendors for the trials. I think it should be handled in there and I think you should get involved as per your role in RI & OPNFV

7A: Select Vendor Candidates for RI installs
(MikeF add) - That is not for RI team to worry about.  → MikeF:  Can RI WS handle the handoff to the appropriate WS?  The ask is for parallel/multiple RI installs.  Who will identify & support these candidates?
8A: Identify Target Labs for RI installs
(MikeF add) - That is not for RI team to worry about.
9B: Outline Trial Partner Expectations & Establish Contact
(MikeF add) → → MikeF:  Can RI WS handle the handoff to the appropriate WS?  The ask is for parallel/multiple RI installs.  Who will identify & support these candidates?

B:  Descriptor File - finalize & perform PoC

Refer to: 

  • [RI 1 Core]: Work with OPNFV Infra WG for the evolvment of PDF to fit into need for CNTT RI #526
  • [RI 1 Labs] Tooling to Generate a PDF matching Airship Internal Data Structure #525

(MikeF add) - That is OPNFV issue not CNTT. need to discuss who should own this. off course CNTT team needs to be part of the discussion, but someone from OPNFV has to take ownership of this and lead that discussion.   → MikeF: Agree.  RI WS is managing this today.  Need handoff from RI WS to OPNFV.  Should keep this open through the handoff.
11
  • A: 1.3 scope: clarify scope as per Prague discussion.

  • A: 2.4 Diagram is not relevant: This should be removed or moved to Chapter 4 (Lab requirement) and improve diagram as it is low quality. Do we need an example section?

Ch02
15
  • A: 3.1 clarify the intention of the chapter (to be able to create a PDF/IDF from the content of the chapter).
  • A: It will be better to simplify the presentation of the content here (metadata driven approach will be recommended)
    • To make it simple to create PDF/IDF from the chapter.
  • A: 3.4 it mixes requirement, with architecture with state. (need to clean up and remove any duplications). Remove any reference to functest or certification or test cases, this should be all about the state of NFVI.

Ch03
13
  • C: Need a Topology Diagram.

Ch04
14
  • B: 5.2 Add more installer general requirement (e.g. the need for it to be opensource, the result of it needs to be opensource).

Ch05
15

A: Create a Cookbook for Labs (how to access labs, types of labs available, etc)


Ch06
16

A:  lot of clean-ups needed.

  • Not mix labs with installation (Chapter 6 deals with labs)
  • 7.2, 7.3, 7.4 will need to move to Chapter 6 since they are lab related.
  • 7.6, 7.7 (clarify difference between deployment validation and development validation).
  • This should be sanity check and not extensive testing.

Ch07
17

C: Need some initial content (are there no gaps? )


Ch08

Development

18B: Descriptor File - finalize & perform PoC
Work with OPNFV to agree on approach for handling Descriptor Fromat for various installers.
19A: Ensure RI-1 lab is installed / available for tests.

Confirm that the CI/CD Scripting works (Natural bi-product of lab install success) 

20A: Endure that funkiest is able to repeatedly validate the installation of RI.

21A: RI-1 passes the RC-1 sanity check
  • RI supports RC
  • Define pass criteria for sanity check
