3. Component Description:
...
- Network Service Lifecycle Manager (nslcm ) which is the core component of VFC VF-C NFVO, mainly responsible for network service management.
- Catalog is used for package management, including NS/VNF/PNF package management.
- Resource Manager is used for the management of the instances that are created by VF-C and is also responsible for resource granting operations.
- Specific Virtualised Network Function Manager (S-VNFM) Driver. VF-C currently has three vendor’s Specific VNFM drivera, including Nokia, Huawei, ZTE drivers, where each driver is a microservice.
- Generic Virtualised Network Function Manager (G-VNFM) Drivers. VFC VF-C can now have two generic VNFM drivers, the gvnfm driver and juju vnfm driver.
- Workflow is comprised of 2 microservices, the vfc-workflow that provides the workflow management services and the vfc-workflow-engine which is the activiti workflow engine microservice.
- Multivim-proxy, provide interfaces to forward virtual resource requests to MultiCloud for resource checking ( Vim Assignment ) and Network resource creation.
- EMS Driver is used for VNF performance and alarm data collection and report to DCAE via the VES collector.
- GVNFM provides the ONAP Generic Virtualised Network Function Manager capabilities. GVNFM is composed of three microservices: vfc-vnflcm, vfc-vnfmgr and vfc-vnfres. The core microservice vfc-vnflcm is responsible for VNF life cycle management.
