The Ribbon Virtual Network Function Manager (VFM) is a generic VNF Manager in the ETSI open standards OpenStack NFV architecture, performing full life cycle management (LCM) of multiple Ribbon VNFs and third party VNFs. The VFM interfaces with network orchestrators (NFVO) and virtual infrastructure managers (VIM) to ensure elastic scalability of VNFs based on dynamic network load and/or provisioning state.
VNF Life Cycle Management
Service providers can onboard, instantiate and scale VNFs as required across multiple data center locations using the VNF Manager (VFM). It provides indications of all managed VNF lifecycle events (instantiation, scale-in/out/up/down, fault events, alarms, licensing, etc.) and behaves in a stateful manner to interactively request authorization for instantiation and enabling capacity on demand through scale-in/out events from the NFVO and VIM.
Instantiation and orchestration of VNFs is a fully automated function of Ribbon's VNF Manager, with support for on-boarding through templates. Configuration files are auto-loaded (and are changeable) to configure capabilities such as minimum deployment configurations for VNF patterns. Northbound REST, NETCONF, and SOAP/XML APIs enable the VNF Manager to adapt to a larger orchestrated ecosystem, which the service provider may provide to orchestrate VNFs across multiple vendors per the NFV architecture. VFM also offers multiple datacenter/cloud support across geodistributed topologies.
Ribbon's VNF Manager integrates with various network orchestration platforms as well as operator-specific implementations.
