Overview

More information and current status can be found on the wiki for FEAT06NSPackage

Feature Prime	Bhumip Khasnabish (ZTE), Haibin Chu (Ericsson) and Yaoye Zhang (Huawei)
Feature description	An NS Package is an archive including the meta-model descriptors NSD and other files (scripts, security materials, possible rules, policies, NS over multi-tenants, etc.), that are required to manage an NS from design to test/verification to validation/certification to runtime management; the holistic end-to-end NS lifecycle, as discussed in NFV(17)000247.
Target Release	Release 3 drop 1 (2018-06)
Impacted WIs	IFA010, IFA012 (TBC), IFA013, and IFA014. Note-1: We identify the impacted specifications in IFA WG only. The impacted specifications in other WGs (e.g. SOL, TST, SEC, REL, etc) needs to be addressed separately and the chairs of SOL and TST WGs have been informed. We will follow up the impacts on SEC and REL WGs. Note-2: The impact on IFA012 is dependent on the ISG's decision whether IFA012 is released as GS or GR by the end of Y2017.

Issues

List of issues raised based on the feature implementation.

- All topics can start from the beginning but the progress needs to be managed on the action IDs (e.g. individual mega CRs and new deliverable basis)
- The target dates are set according to the requirement categories in IFA022 (CRs for general, functional, reference point and information element, descriptor, or new deliverable)
- Discussion for IFA032 may take more time than CRs but finalise before the 1st drop of Release 3.

Issues

List of issues raised based on the feature implementation.
With regards to specific planning action:

• Action 004: description is deemed complete, but needs to be checked with some additional clarification or references to possible informative flows are needed.
• Action 007: main content is available and approved, but some editor's notes need to be resolved (see action 013).
• Action 008: main content is available and approved, but some editor's notes need to be resolved (see action 013).
• Action 010: main content is available and approved, but some editor's notes need to be resolved (see action 013).
• Action 004/006/008/010/011: need to analyze and define the relationship of NFV-MANO Service and interfaces.
• Action 009: main content is available and approved, but some editor's notes need to be resolved (see action 013).
• Action 009: the "heartbeat" functionality was deleted in the approved FM interface and IE contribution (see NFVIFA(18)000215r2). It needs to be resolved how the heartbeat functionality relates to fault management, or whether it needs a specific interface for it.

Other issues:

• (Jan. 2018) At IFA#84 F2F meeting: discussed the possibility of having some informative information flows to show examples on how the interfaces can be used. An Annex could be added.

Security Considerations

List of security considerations implied by the feature.

• As captured in some editor's notes in clause 6: Editor’s Note: actors in the operations are “consumer” and “NFV-MANO functional entity”. The consumer is intended to be an authorized consumer, thus, not all possible consumers may be authorized to access all operations. Further description and analysis about this is expected to be part of the “Security Considerations” clause.

FEAT15: VNF Snapshotting

Overview

Feature Prime	Jörg Aelken (Ericsson LM)
Feature description	The VNF_PHOTO is a feature that has been investigated and described in the published ETSI GR NFV-TST 005. A VNF Snapshot is a replication of a VNF instance at a specific point in time with a corresponding VNF Snapshot Package which is collection of files representing a VNF Snapshot. The feature implementation enables operations on and management of VNF Snapshots and their corresponding packages.

NOTE: An alternative solution for a VNF Snapshot Notification Interface in IFA008 could be to add a new VNF Snapshot notification type to the VNF LCM interface. The final solution will be developed when working on the items for IFA008. After investigation of the alternative, it was decided to implement this alternative by re-using the VNF lifecycle notification interface and adding an operation to enable the VNF/EM to confirm the received notification concerning VNF snapshotting.

Issues

Background Information

According to its latest definition, the ETSI NFV Release 3 includes objectives:

• To specify requirements and enhancements to NFV Architectural Framework to support PaaS features.
• To specify non-functional parameters to classify and characterize VNF cloud-native implementations.

They are reflected in the following two features and corresponding work items:

Feature ID	Title	Work Item
R03.F19	NFV Architecture PaaS (NFVPAAS)	IFA029
R03.F20	Cloud-Native VNF (VNFCLOUD)	EVE011

During the work on the two work items it was discovered that both features are very much related and the envisioned solutions and implementations might overlap and will target the same impacted work items.
During discussions in IFA#73 it was further identified that EVE011, even though it is normative, should be considered as stage 1 requirements on cloud-native on a high abstraction level without taking the actual implementation into consideration. It was further identified in this meeting that IFA029 as a GR looks at architectural aspects of both Cloud Native and PaaS.

Feature implementation approach

This feature implementation plan proposes to implement both features, VNFCLOUD and NFVPAAS, together. It is proposed to delay the feature implementation and aim for ETSI NFV Release 3 drop 2 with the following approach:

• Finalize EVE011 and get it approved
• Analyze EVE011 for potential architectural impacts and evolve them in IFA029
• Get IFA029 in a stable stage
• Implement both features based on recommendations from IFA029 and recommendations from EVE011 which could be directly implemented
