32、he alarm data flow and the alarm mapping of VNF instance application alarm and VNF instance related virtualized resource alarm are described as below: - Flow-1 VIM reports virtualized resources alarm data to VNFM (out of scope of the present document). - Flow-2 VNFM sends VNF alarm data related to v

33、irtualized resources (mapped to VNF instance, correlated or not-correlated) to EM. - Flow-3 VNF reports virtualization-specific alarm data to VNFM. - Flow-X Via 3GPP Type 1 interface VNF instance reports VNF instance application alarm data and virtualization-specific alarm data to EM. - Flow-Z Via 3

34、GPP Type 1 interface non-virtualized NEs report alarm data to EM. - Flow-Y Via 3GPP Itf-N EM sends the following: VNF instance application alarm data and virtualization-specific alarm data (received via Flow-X), VNF alarm data related to virtualized resources (received via Flow-2),non-virtualized NE

35、 alarm data (received via Flow-Z), and/or correlated VNF instance alarm data. EM may make the alarm correlation based on information contained in Flow-X, Flow-Z and Flow-2, using the same VNF/VNFC instance identifier based on the VNF instance alarm data related to virtualized resource and VNF instan

36、ce application alarm data. EM may report the correlated VNF instance alarm data to NM. NM may make the alarm correlation based on information contained in Flow-X, Flow-Y, Flow-Z and Flow-2, using the same VNF/VNFC instance identifier based on the VNF instance alarm data related to virtualized resour

37、ce and VNF instance application alarm data. The procedures listed in clause 4, as some of all the possibilities, are not exhaustive.

38、the context of NFV When a new failure occurs from the virtualized resource and it impacts the corresponding NE application, EM can make the alarm correlation based on the virtualized resource failure report sent from VNFM and VNF application alarms.
