Re: [OPSAWG] WG adoption poll for draft-song-opsawg-ntf

Hi Qin,

Thanks for the comments. We'll provide more description about this issue and make reference to the existing work. 
Your second observation is also right. There are different meanings when talking about correlation. I think "data correlation" can serve as a high level term to cover both cases.

Best,
Haoyu

Event,defect correlation at different layer is a challenging issue we try tackle in LIME WG, see charter scope:
" The absence of a common approach to OAM management has made it difficult for operators to:
  - Suppress large numbers of unnecessary alarms and notifications related to defects and failures arising in lower layers and visible in each higher layer
  - Quickly identify root causes of network failures
  - Coordinate end-to-end performance measurement with the results of performance monitoring at different layers in the network
  - Correlate defects, faults, and network failures between the different layers to improve efficiency of defect and fault localization and provide better OAM visibility.
"
If this issue can be further addressed by NTF, that will be great. I would recommend to reference LIME work as basis which will be published soon.
Also I think KPI correlation rely on big data analytics technology, data correlation from different source and KPI correlation are two different things.
