TR255 Resource Function – Activation and Configuration v5.0.1

The purpose of this document is to define use cases and requirements for the provisioning and life cycle management of Resource Functions (RF). Examples of RFs are Virtual Network Functions (VNFs) and Network Services (as defined in ETSI NFV), Service Functions and Service Function Chains (as defined in IETF), and physical network functions such as routers and Content Delivery Networks (CDNs). The use cases and requirements are intended to drive the definition of an associated TM Forum API. The use cases and requirements are divided into two basic kinds, i.e., intent-based and detailed-based. In the case of intent-based, the consumer does not have a view or the ability to directly affect the components of a given entity. For the detailed-based, the opposite is true.
