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 the industry and different players define its components, breadth, and depth in slightly different ways

SDPs are commonly considered for the telco type environments as a core system which interconnects the customer's access and network infrastructure with the OSS systems and BSS systems. SDPs in this context are usually associated with a particular service regime such as mobile telephones or for converged services
