NNI Use Case - discovering 2 topologies from the network

Use case is asking for the ability in AAI to link an underlay and overlay together by having a cousin relationship between 2 PNFs.  Asking @Chandra Cinthalato verify if that edge rule can be added for the Frankfurt release.

Per Chandra: "I think pnf -> pnf edge is redundant and not needed as we can traverse (thru a logical or physical interface) from pnf -> p-interface/l-interface -> pnf."

Search guard issue

@Giulio Graziani

ON HOLD

Merged and released yesterday; issue is closed. 

AAI-2617: Search guard is no longer availableClosed

Tracking for Frankfurt:

https://lf-onap.atlassian.net/browse/AAI-2677

Search guard container no longer available so elasticsearch-sg won't build.  Search guard allows us to secure the elastic communication, which in older versions was not available but newer versions have support for secure communication.

https://www.elastic.co/blog/dear-search-guard-users

Consider opendistro as replacement for search-guard

Can we consider this one:

E2E Network Slicing

@LIN MENG

OPEN

For the E2E Network Slicing use case for Frankfurt Release, we intend to leverage the nested service model work that has been going on since Dublin release. From A&AI perspective, we foresee that the schemas would have to be enhanced to cover network slicing models. We have considered A&AI to be a stretch goal for Frankfurt, though we are committing resources. So, we would like to start the discussion in the coming weeks, and subsequently implementation work to try our best to complete the implementation for Frankfurt. AAI-2600 has been created just to indicate the SDC impacts, we will update it with more details, and also join the A&AI weekly call during the next 1-2 weeks to discuss further.

Portal SDK Upgrade

@James Forsyth

OPEN

AAI-2726: Update to Portal SDK v2.6Closed

@Francis Paquette  need evaluation of feasibility in Frankfurt for sparky

GraphGraph Image Missing in Nexus

@Venkata Harish Kajur

OPEN

Graph Graph Images are missing from nexus and it needs to be resolved in order for elalto deployment to be successful.

OOM-2161

How did this docker image get pushed to nexus and why was it removed from nexus?  

Graphgraph was removed from the default helm chart, but we still need to get these jobs fixed.

Data-router not starting

Java 11

@James Forsyth

ON HOLD

@Venkata Harish Kajur tried schema service, a couple of dependency changes were required to get it to start. Eclipselink that is currently configured is incompatible.  

<groupId>javax.activation</groupId>
<artifactId>activation</artifactId>

is also incompatible

Needs more investigation for other repos

Need new common image (which Alpine image would we pick?)

Upcoming R6 Functional Requirements

@Benjamin Cheung

IN PROGRESS

Release 6 (Frankfurt) proposed use cases and functional requirements

Use Case Realization Call: September 25, 2019

AAI-2600: A&AI support of Network Slicing Demo in FrankfurtClosed

We have created REQ-158 - 

Open

for this use case. For AAI impacts, we have created AAI-2600 - A&AI support of Network Slicing Demo in Frankfurt.Reg. details of the AAI impacts, this is still being worked out, as there is an alternative proposal, and we are trying to align w.r.to scope & impacts. We will share more details in the coming days. The overall use case will also be presented to the Architecture Sub-committee for approval (based on the f2f discussions that happened in Antwerp 2 weeks ago).

AAI-2670: AAI changes in support of 5G/OOF SON (PCI)Closed

AAI-2671: AAI changes in support of BBSClosed

We are currently reviewing the list of items we found in the BBWF BBS testing and once we sort through them we will communicate the results back to ONAP community.

Regarding AAI specifically, we do not foresee any new requirements for Frankfurt, but we would like to conclude the review first before jumping to final conclusions.

AAI-2672: AAI changes in support of HPA ContinuationClosed

AAI-2673: AAI changes in support of K8S Based Cloud Region SupportClosed

We are not expecting any changes at this time. Tech Mahindra is working on populating a&ai with the VNF specific information from K8S. There is a chance that we realize some changes to the schema, but we don’t expect any changes to the code.

https://lf-onap.atlassian.net/browse/AAI-2674

During run-time solution there are AAI impacts. Run-time solution is not planned for Frankfurt release. Only Import Service Catalog solution in SDC is targeted for F release.

AAI Impact highlights:

After Service Order decomposition in SO, CFS Service Instance details will be stored in AAI.

After response from 3^rd^ Party Domain, RFS instance details will be updated in AAI.

The sequence diagram  depicts the run time view  of Third Party Order Activation using the on-boarded service definition and highlights AAI impacts.

ReUse in AAI:

We plan to leverage the SPPartner model, created for CCVPN, to store the 3^rd^ Party details in AAI.

org.onap.aai.domain.yang.SpPartner present in aai-schema v15

https://lf-onap.atlassian.net/browse/AAI-2623

Have done some prototyping in Dublin to ingest topology from external controllers and show them in A&AI. Will need more work to act on notifications from controllers and keep the topology in sync

https://lf-onap.atlassian.net/browse/AAI-2678

For the 5G Bulk PM use case in R6, I’m attaching a few slides showing how we think AAI can be used as part of the UC realization. We are currently making the following assumptions:

• PNF and VNF models contain status attribute that can indicate when a new instance has been fully instantiated (may still require update to SO workflow)

• AAI will send topology event on AAI-EVENT topic when status attributes are updated

Can you review the slides and the assumptions above and let us know if you see any issue. We can also setup a separate meeting if needed.

Note: I will share the same slides on the SO weekly meeting today.

Frankfurt Release Requirements

Migration

@Ankit Bhatt

IN PROGRESS

What is the purpose of MigrateCloudRegionUpgradeCycle migrator in onap graphadmin migration framework?

From Casablanca to Dublin, should these be run?

• v14/MigrateMissingFqdnOnPservers

• v13/MigrateVnfcModelInvariantId

• v13/MigrateModelVer

Migration will check if it's already been run, and won't run again.

Jira task created to track this: AAI-2689

5) Strategy for oparent dependency management

ESR

@James Forsyth

@Bo Lv
@Former user (Deleted)

IN PROGRESS

Need to know if the ZTE team who built ESR intends to continue to support this sub-project in Frankfurt.  Multiple Jira issues were not worked in Dublin / El Alto, which leads me to think that the ESR project might need to be deprecated.  Inviting @Bo Lv and @Former user (Deleted)to see what the current status is.

Hi, we didn't have resources for ESR in El Alto, and I(Huabing Zhao) and Lv Bo won't be able to contribute to ESR in F release, but @Peng He will continue supporting  ESR in F release on behalf of ZTE team. Please add him in the loop for the ESR related issues.

NFS node is 10.12.5.10

Followed these instructions https://docs.onap.org/en/latest/submodules/oom.git/docs/oom_setup_kubernetes_rancher.html?

Need to determine what gets installed, testing opportunities, CSIT, distribution flows, etc.

v17 schema for Frankfurt

@shashikanth.vh

ON HOLD

Since the CCVPN SOTN proposal is in progress already, could we have the v17 schema introduced into master branch to receive the updates for Frankfurt release? https://lf-onap.atlassian.net/browse/AAI-2607

See also AAI-CCVPN-Extension-SOTN Proposals for Frankfurt Release and https://lf-onap.atlassian.net/browse/AAI-2593

https://lf-onap.atlassian.net/browse/AAI-2594 already added some v17 files but needs more work to be complete.

Performance Issue

@FREEMAN, BRIAN D reported that when there are ~2400 vservers returned in a closed loop custom query, AAI takes minutes to respond.  We've discussed paging previously, any other ways to optimize this?

Spring Boot 2

@James Forsyth

IN PROGRESS

https://lf-onap.atlassian.net/browse/AAI-2111

aai-common:1.5.2 (not released yet) will be the el-alto library for springboot 1.5.x microservices.  There needs to be some urgency to migrate the microservices to spring boot 2, since 1.5.3+ will not be backward compatible and so dependent applications might not have security updates if they stay on 1.5.2.  1.6.0 (Frankfort, currently master branch) aai-common will be springboot 2 so microservices must be updated by Frankfurt.  Springboot 1.5.21 is the latest (and last) version in the 1.5.x spring boot train.
