T-NOVA project released its first specification document, identifying use cases and requirements for an integrated Virtual Network Functions as-a-Service (VNFaaS) platform, such as the T-NOVA system. From a business point of view, the document proposes multiple value chain configurations, involving actors such as Infrastructure Providers, VNFaaS Service Providers and Function Developers. Elementary VNFaaS use cases cover all technical and commercial aspects and include: service composition, trading, provision, scaling, monitoring, billing and termination. High-level system requirements are derived from the list of use cases. Read the document here.
