VNF-related possible enhancements to future releases (from the "Guidelines for Virtual Network Functions in a Network Cloud" document):

• Open source software and demos of simple reference VNFs
• Automation of VNF onboarding and other aspects of VNF lifecycle
• Consistent VNF packaging for automated onboarding using OpenECOMP
• Other implementation examples for targeted virtualization environments, such as those located beyond the data center at the network edge or customer premises
• Incubation and Certification Environment (ICE), a self-service program to gauge maturity and readiness of VNFs
