Summary

0008204: [4.3.1] [Section 9.5.3.9] Conflicting definition of the attribute "vimConnectionId" in VimComputeResourceFlavor definition

Description

The section 9.5.3.9 reads, "If the VIM requires the use of virtual compute resource flavours during compute resource instantiation, it is assumed that such flavours are selected or created by the NFVO based on the information in the virtual compute descriptor defined in the VNFD".

Which means, this is a structure that could be used even in a state where there is no VNF-instance present. However, the table "Table 9.5.3.9-1" defines the attribute of the data type VimComputeResourceFlavour, as:

---
vimConnectionId Identifier --> 0..1 -->

"Identifier of the VIM connection to access the flavour referenced in this structure.

The applicable "VimConnectionInfo" structure, which is
referenced by vimConnectionId, can be obtained from the
"vimConnectionInfo" attribute of the "VnfInstance" structure.
... "

The above description infers the attribute "vimConnectionInfo" can be fetched from a "VnfInstance" which may not exist in the system yet.

Additional Information

Need clear examples and description of where/how can one fetch the value of "vimConnectionId" for VIMs (or CISM) where the Vnf Instance may not exist yet.

(0016475) Sujeet Banerjee (reporter) 08-05-2023 14:46	Same issue for the section "9.5.3.10 Type: VimSoftwareImage"

(0016526) Yinan Liu (developer) 11-09-2023 02:30 edited on: 11-09-2023 02:58	I have created NFVSOL(23)000296r1 assingd to SOL#260(NFV#43) to resolve this issue. In this contribution, I add a condition "when VimConnectionInfo is available" for the case that VnfInstance exists and vimConnectionId is obtained from VnfInstance->VimConnectionInfo. Could you check whether you have additional comments? I plan to make this issue resolved after this contribution is approved by NFVSOL.

(0016527) Sujeet Banerjee (reporter) 11-09-2023 06:21	Looks good. Thanks.

(0016528) Yinan Liu (developer) 19-09-2023 11:09	NFVSOL(23)000296r1 has been approved on SOL#260(NFV#43) day1 AM2. The SOL#260 report also marks issue ID8204 as CLOSED. Therefore, I change the stutas to RESOLVED.
