1. Frankfurt Improvements
| No. | Track | Description | Jira | Priority | Impacts | Remarks |
|---|
| 1.1 | NST selection | Implementation of NST selection in HAS |
| 1 | HAS | Common understanding of how to fetch template details from SDC |
| 1.2 | Implement callback for NST selection |
| 1 | OSDF, SO |
|
| 1.3 | NSI |
/NSSI | selection | API improvements - For NSI |
/NSSI fetching - from SDC or to | should be provided in the request from SO (NSMF). NumSolutions should be provided by SO |
OSDF? | Common understanding of how to fetch template details from SDC | 1.4 | During NSI/NSSI | . Service/Slice Profile attributes, json blob at the end |
| 1 |
| Domain type (AN/TN/CN) should be also included in the Slice Profile (Modeling consideration?) |
| 1.4 | OOF response shall NOT contain NSSI info (only NSI if available/usable, and Slice Profiles will be sent back). |
| 1 |
|
|
| 1.5 | During NSI selection, when the attribute (e.g., reliability) in Threshold Policy is not part of Slice Profile, it should be ignored by HAS (error should not be returned) |
|
| HAS | Already implemented |
| 1. |
5| 6 | Aggregate policy to be implemented, e.g., latency of all |
NSSIs Slice Profiles (across subnets) chosen to be < latency in Service Profile. |
| 1 |
| independent improvement |
| 1. |
6| 7 | When considering existing NSSI as a candidate, consider ALL slice profiles (not just “best” one). |
| 2 |
|
|
| 1. |
7| 8 | Slice profile generation - candidates should be generated at appropriate granularity |
| 1 |
| - To be generated even when reusing an existing NSI
|
?- Which parameters to generate (per domain type) to be policy driven or come from Slice Profile Template, as well as should depend on the parameters received in the service profile
|
| 1. |
8| 9 | Slice profile selection - choose best one, based on service profile, subnet capabilities (and optionally existing NSSIs, if sharing is allowed???) |
| 1 |
.9 |
| Priority can be revisited |
| 1.10 | Implement callback for NSI |
/NSSI , SO1.10 | API alignment - service/slice profile parameters, json blob at the end | OSDF, | Additional components - SO |
| 1.11 | Selecting "final" solution(s) by OOF based on policy - minimum change policy, maximum slice count policy, reuse policy, etc. |
OSDF?| subject to the numSolutions limit sent by SO. |
| 2 | HAS
| OOF API |
also to be updated to remove the shall still contain 'list' of solutions OSDF - translation of Policy |
| 1.12 | NSI |
/NSSI Response | API and response for NSI termination - yes or no (check Policy also) |
| 1 - functionality 2- OOF impacted | OSDF, SO | Request should come from SO acting as NSMF |
2. NSSI Selection
| No. | Track | Description | Jira | Priority | Impacts | Remarks |
|---|
| 2.1 | .13Response | NSSI Selection | Select appropriate NSSI, return "no solution" if no solution exists (Send Slice Profiles also in case of RAN NSSI selection for Option 1) |
| 1 |
| Intention is to make NSSI selection domain agnostic. |
| 2.2 | Implement callback for NSSI selection |
| 1 |
|
|
| 2.3 | NSSI Termination | API and response for NSSI termination - yes or no (check Policy also) |
| 1 - functionality 2 - OOF impacted | OSDF |
