34、ces alarm data to VNFM (out of scope of the present document). - Flow-2 VNFM sends VNF alarm data related to virtualized 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 ins
35、tance reports VNF instance application alarm data and virtualization-specific alarm data to EM. - Flow-Z Via 3GPP 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 (
36、received via Flow-X), VNF alarm data related to virtualized resources (received via Flow-2),non-virtualized NE 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 VN
37、F/VNFC instance identifier based on the VNF instance alarm data related to virtualized resource and VNF instance 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,
38、using the same VNF/VNFC instance identifier based on the VNF instance alarm data related to virtualized resource and VNF instance application alarm data. The procedures listed in clause 4, as some of all the possibilities, are not exhaustive. 4.2 NE alarm correlation in the context of NFV 4.2.1 NE a

The VNF and/or VNFC alarms
43、 related to virtualized resource include AlarmId, affected VNF identifier, affected VNFC identifiers, and FaultDetails which provides additional information about the virtualized resource fault, for example the resource identifier which causes the fault (e.g. VM identifier, vNIC identifier or vPORT
44、identifier). The Alarm information element see clause 9.3.4 of 3. 4) NE/VNF sends VNF application alarms to EM through proprietary interface, the corresponding VNF instance identifier and/or VNFC identifier should be included. NOTE: There is no sequence restriction on EM receives VNF instance alarms
45、 related virtualized resource and EM receives VNF application alarms. 5) EM correlates the received VNF instance alarms related to virtualized resource with the received VNF application alarms. 6) EM sends the correlated alarm information to NM over Itf-N.
