NOTE: This poll closes on Thu March 8th, 2018


HPA is a desired feature to be supported in R2, but no agreements have been reached on the attributes to be included into the clean version. This poll is to decide which (or all) of these attributes are to be included in the clean version (R2 IM).

Attributes include (defined in ETSI IFA011 v2.4.1):

  • vduCpuRequirements (attribute of IE/class VirtualCpuData)
  • vduMemRequirements (attribute of IE/class VirtualMemoryData)
  • vduStorageRequirements (attribute of IE/class VirtualStorageDesc)
  • logicalNode (attribute of IE/class VirtualComputeDesc)
  • nicIoRequirements (attribute of IE/data type VirtualNetworkInterfaceRequirements)
  • networkInterfaceRequirements (attribute of IE/data type VirtualNetworkInterfaceRequirements)

Examples of the above attributes can be found at https://wiki.onap.org/pages/viewpageattachments.action?pageId=24051740&metadataLink=true, or if you have ETSI account, NFVIFA(18)000162 contribution.

Poll Question

Which (or all) of the attributes you would like to include in R2 IM?

Option 1: include this attribute in the clean version (same as IFA011)

Option 2: include this attribute in the clean version and remove other redundant (legacy) attributes (modification based on IFA011)

Option 3: not include this attribute in the clean version

Please put your @name in one of the option column for each attribute (or the "ALL" for simplicity) and provide any comments you might have.

All the listed attributes (for simplicity).
vduCpuRequirements





Xu Yang: Possible redundant attributes: numVirtualCpu, virtualCpuClock, logicalCpuPinningPolicy, logicalCpuThreadPinningPolicy, computeRequirements

Alex Vul: the computeRequirements attribute is not HPA related.

Alex Vul: These are not redundant. If I remember right, they are complementary...

vduMemRequirements





vduStorageRequirements





logicalNode


Xu Yang: Question: In the example document, the logical node requirements are categorized into compute, memory and network categories. But in IFA011, only one logicalNode attribute is defined, what's the mapping here?

Alex Vul: There is a single k/v array holding attributes from three registries... We will optimize this, when registries are created.

nicIoRequirements


Xu Yang: Question: related to the above comment, if the network logical node requirements are specific, should this be a dedicated data type instead of a reference?

Alex Vul: Hmm... Need to think about it. As I review both the NFV Profile based spec and the SOL spec, I am finding some oddities.. We may have a mistake or two in how things got modeled..
