The GENBAND Virtual Network Function (VNF) Manager (VFM) is a generic VNF-Manager in the ETSI VNF Architecture managing life cycle management of multiple GENBAND and third party VNFs. The VFM interfaces with network orchestrators (NFVO) and virtual network managers (VIM) to ensure elastic scalability of VNF’s based on dynamic network load and/or provisioning state.
GENBAND VNF Manager (VFM)
Service providers can scale the VNFs as required across their data center locations using the GENBAND VNF Manager (VFM), which enables capacity on demand through:
- Integration with NFVO (NFV Orchestrators)
- Automated service turn-up and turn-down
- REST API and GUI control of all VNFM Functions
- Fully automated control of elasticity
- Automated provisioning of elastic resources/applications
- Lifecycle VNF management
- VNF Licensing, including OPEX pay-per-use model enablement
- Automated control of SDN infrastructure
GENBAND’s generic VNF Manager integrates with various network orchestration platforms as well as operator-specific implementations. It provides indication of all VNF managed events (instantiation, scale-in/out, fault events, alarms, licensing, etc.) and behaves in a stateful manner to interactively request authorization for instantiation and scale-in/out events from the NFVO.
Instantiation and orchestration of VNF’s is a fully automated function of GENBAND’s VNF Manager, with support for on-boarding through templates. Various configuration files are auto-loaded (and are changeable) to configure capabilities such as minimum deployment configuration for VNF patterns. Northbound REST, NETCONF, and SOAP/XML APIs enable the GENBAND VNF Manager to adapt a larger orchestrated ecosystem, which the service provider may provide to orchestrate VNF’s across multiple vendors per the NFV architecture. VFM also offers multiple datacenter/cloud support.
