Vnfd and VNF instance model

Classes

BaseConfigGroup

Every Vnf contains a BaseConfigGroup. BaseConfigGroup may set Access Control Lists (ACL’s) and establish security groups and server groups. BaseConfigGroup reates/establishs storage for the VM’s (OpenStack Cinder). BaseConfigGroup may establish internal networks such as OAM (VNF Mgmt) or MNS (Maintenance & Surveillance) established. A very simple VNF may only have a BaseConfig VnfElementGroup.

HomingGroup

Homing selects what cloud selection strategy will be used. HomingGroup is used to determine where VNF’s within a given group are placed with respect to a service component. Homing strategy is as follows: Colocation - members of the group share the same cloud region (VIM Domain) isolation - members of the group do not share the same cloud region.

SecurityGroupRule

Security group rule specifies the matching criteria for the ingress and/or egress traffic to/from the visited connection points. If an ingress traffic is accepted, the corresponding egress response shall be allowed, regardless of the security group rules on the egress direction. If an egress traffic is allowed, the corresponding ingress response shall be accepted, regardless of the security group rules on the ingress direction. The design of security group rule follows a permissive model where all security group rules applied to a CP are dealt with in an “OR” logic fashion, i.e. the traffic is allowed if it matches any security group rule applied to this CP.

Vdu

The Virtualisation Deployment Unit (VDU) is a construct supporting the description of the deployment and operational behavior of a VNFC. A VNFC instance created based on the VDU maps to a single virtualisation container (e.g. a VM). A VNFC will only be in one VNFDesc. If a vendor wants to use the VNFC in mupliple VNFDesc (their product) they can do so, but it will be ‘repeated’.

Future

Specifies the number of VNF instances required for an NS level. NOTE 1: It shall be in the range of minNumberOfInstances-maxNumberOfInstances, as specified in the referenced VnfProfile. NOTE 2: When the corresponding NS level is used in the context of NS instantiation, the numberOfInstances attribute specifies the number of VNF instances to be deployed. NOTE 3: When the corresponding NS level is used in the context of NS scaling, the numberOfInstances attribute does not specify the number of VNF instances to be added/removed when reaching that NS scale level. The actual number of VNF instances to be added/removed can be derived by subtracting the numberOfInstances declared in the source NS scale level from the numberOfInstances declared in the target NS level of the scaling request.

VnfcConfigurableProperties

This datatype defines the configurable properties of a VNFC. For a VNFC instance, the value of these properties can be modified through the VNFM.

Enumerations

CollectionPeriod

Specifies the periodicity at which the producer will collect performance information. Note: at the end of each reportingPeriod, the producer will inform the consumer about availability of the performance data collected for each completed collection period during this reportingPeriod. While the exact definition of the types for collectionPeriod and reportingPeriod is left for further specification, it is recommended that the reportingPeriod be equal or a multiple of the collectionPeriod. In the latter case, the performance data for the collection periods within one reporting period would be reported together.
