FEAT12: Enhancement support for MEC in NFV deployments

Overview

Feature Prime Uwe Rauschenbach, Nokia
Feature description Update to selected NFV interfaces. The intent is to define extensions which can be used to specify how ETSI MEC can be deployed in an NFV environment, allowing to run MEC applications on the NFVI besides

VNFs, and re-using ETSI NFV MANO components to perform common MANO tasks on the MEC applications.

3 parts:

  • Small Os-Ma enhancements (to be started, waiting for MEC requirements)
  • Small Ve-Vnfm enhancements (finalized, can re-use LCM coordination interface that has been defined as part of updating FEAT15 in IFA008ed321)
  • Support for Non-MANO artifact sets in VNF package (finalized IFA011/SOL004 ed251)

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

Summary of decisions / agreed concepts

  1. Based on 3GPP's answer below, FEAT05 assumes that current NS LCM can be used by slicing to build slices and slice subnets.
  2. Based on 3GPP's answer below, FEAT05 can concentrate on analysing the use of NS priority only.
  3. Based on 3GPP's answer below, FEAT05 expects that a NS instance doesn't need to keep track of different consumers of a NS instance, but the existing multi-tenancy concept can be used by 3GPP.
  4. Based on 3GPP's answer below, FEAT05 closes the work on slice specific policies and multi-domain issues.

It is expected that Slice management functions can build the slices by using (instantiating) NS instances. NFV MANO is not aware of the network slices. Thus slice consumers / tenants are not known by MANO. Only the NS tenant is seen.

Depending on the use cases (contributed to an Annex for IFA010), it will be decided whether NS priorities need to be propagated to VNFM or VIM.

Overview Liaison Exchange

Specific Liaisons with 3GPP SA5 on Network Slicing

Summary of the answers:

  1. The definition of slice specific policies is not within the scope of ongoing Rel-15 work items
  2. Assurance data and Performance Management work item may have potential impacts on ETSI GS IFA027, but no detailed information
  3. 3GPP relies on the use of ETSI NFV NS concept. Current expectations are for the support of priorities at the NS level (e.g. expressed as attribute value in the NSD).
  4. Fixed mapping of slice tenant and NS tenant was not explicitly confirmed. Keeping track of multiple consumers doesn't seem to be necessary. 3GPP is aware of the NS tenants and will use the concept by some mapping between the slice consumer and the tenant of supporting NS(s).
  5. According to the answer, 3GPP is not planning to share NS instance between two slices if isolation is needed.
  6. 3GPP expects that slicing management will use Os-Ma-nfvo and Ve-Vnfm-em reference points only.

A second set of questions has been sent to 3GPP SA5:

Reply by SA5: NFV(18)000299_Reply_LS_from_3GPP_SA5_on_clarifications_topics_for_NFV_NS_i Main issues that could be clarified:

  • Priorities are meant for LCM operations and resolution of resource conflicts in case of shortage
  • MANO can act autonomously using the priority values
  • If priority values are the same, MANO should act “first come first served”
  • There should be a top priority, i.e. one that cannot be pre-empted.
  • SA5 prefers the priority as attribute in NSD-DF.

Open questions collected:

  1. 2.1.1: “3GPP will expect to receive a notification” might be understood that the consumer will receive the notification.
  2. 2.1.3: “For LCM actions on NFV NSs that potentially impacts 3GPP communication services, MANO should ask permission for such LCM actions the 3GPP management system and not use the provided NS priority” is unclear in the wording.
  3. What should MANO use instead if it shouldn’t use the priority?
  4. 2.1.3: It is unclear how NFV should know which NS would impact 3GPP communication services and not be allowed to use the priority.
  5. 2.1.4.1: 3GPP doesn’t acknowledge here that there might be other consumers for NS/resources that may use resources and need to be considered in the setting of priorities.
  6. 2.1.4.2: The wording allows also pre-emption in case a low priority NS instance is fully instantiated. Does 3GPP intend this or do they refer only to NS LCM operations being in execution at the same time concurrently?
  7. Should MANO use priority during autohealing and “kill” a low priority NS instance to be able to heal a high priority NS instance in a resource shortage situation?

IFA032 May-2018 Completed

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.

With regards to specific planning action:

  • CLOSED: Action 004: description is deemed complete, but needs to be checked with some additional clarification or references to possible informative flows are needed.
    • Status: completed. Additional content was added as part of action 013.
  • CLOSED: Action 007: main content is available and approved, but some editor's notes need to be resolved (see action 013).
    • Status: completed. Additional content was added as part of action 013.
  • CLOSED: Action 008: main content is available and approved, but some editor's notes need to be resolved (see action 013).
    • Status: completed. Contributions addressing the editor's notes have been approved.
  • CLOSED: Action 010: main content is available and approved, but some editor's notes need to be resolved (see action 013).
    • Status: completed. Contributions addressing the editor's notes have been approved.
  • CLOSED: Action 004/006/008/010/011: need to analyze and define the relationship of NFV-MANO Service and interfaces.
    • Status: completed. Additional content was added as part of action 013.
  • CLOSED: Action 009: main content is available and approved, but some editor's notes need to be resolved (see action 013).
    • Status: completed. Contributions addressing the editor's notes have been approved.
  • CLOSED: 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.
    • Status: contributions providing a new interface to handle the heartbeat functionality were available, but they were not discussed. The technical assessment and discussion would be postponed to later IFA031 releases, in order to make sure the completion of a stable version of IFA031 for the Rel. 3 drop #1 (1H2018).
  • CLOSED: Action 011: main content is available and approved, but some editor's notes need to be resolved (see action 013).
    • Status: completed. Contributions addressing the editor's notes have been approved.
  • CLOSED: Action 012: main content is available and approved, but some editor's notes need to be resolved (see action 013).
    • Status: completed. Additional content was added as part of action 013.

Other issues:

  • CLOSED: (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.
    • Status: completed. An annex has been added to add informative information flows. Refer to contribution NFVIFA(18)000449.

Security Considerations

List of security considerations implied by the feature.

  • CLOSED: 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.
    • Status: completed. Additional content was added as part of action 014, and in particular with contribution NFVIFA(18)000578r1.
  • Action 014 (added in May 2018) to list specific security related contributions.

029 Add support for requesting transfer of VNF Snapshot Package image artefacts from the NFVO towards the VIM.
CR draft not required for Release 3 drop 1.
The information on the image artifacts is already included in the information element VnfcSnapshotImageInfo, available after package upload. The NFVO can access this IE after the extraction of the package is requested and can then transfer the images from the VIM using the provided access information.
IFA007 May-2018 Not needed
030 Add support for granting of VNF Snapshot Package operations.
CR draft not required for Release 3 drop 1.
Current assumption is that it is not needed, but instead the NFVO is expected to validate incoming requests based on policies/VNFD and only forwards allowed requests to the VNFM. Might be needed for Snapshot Package management exposed towards EM (IFA008). For further study, might be added as maintenance CR later.
IFA013 May-2018 Not needed
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.
