A service delivery platform (SDP) is a set of components that provides a service(s) delivery architecture (such as service creation, session control and protocols) for a type of service delivered to consumer, whether it be a customer or other system. Although it is commonly used in the context of telecommunications, it can apply to any system that provides a service (e.g. VOIP Telephone, Internet Protocol TV, Internet Service, or SaaS). Although the TM Forum (TMF) is working on defining specifications in this area, there is no standard definition of SDP in industry and different players define its components, breadth, and depth in slightly different ways.
