Abstract
Techniques are described for dynamically adapting virtualized network functions (VNFs) to different target environments. A controller stores device profiles that include configuration data and workflows for resolving configuration parameters for instantiating and deploying a VNF package to form a network service. To support the resolution of VNF configuration parameters, a VNF descriptor for the VNF is extended to include a device family parameter that indicates a shared architecture and configuration parameters. The controller, when instantiating the VNF, may identify a device profile usable for resolving the configuration parameters for the VNF and obtain configuration data from the device profile for creating and configuring a VNF instance for the VNF descriptor. Extending the VNF descriptor to specify a device family allows the VNF to be flexibly adapted for different target environments and may avoid the use of numerous pre-defined VNF descriptors.
