Service Delivery Platform (SDP) can be loosely defined as a standards based framework that facilitates the design, development, implementation and management of services required to run the operations of network services providers. The services could range from the basic voice connectivity to the state-of-the-art rich multimedia services. The most critical value-addition offered by the SDP methodology lies in its ability to abstract controlling parameters such as location, media control, integration and others. SDP interface with the network elements, OSS/BSS, telco IT infrastructure and partners such as application developers and content providers.
SDP, SOA, and IMS
IP Multimedia Subsystem (IMS) driven initially by the Third Generation Partnership Project (3GPP) to add centralized control to IP applications for GSM and later augmented by the 3GPP2 to support CDMA networks has many of its foundations in work done by the Internet Engineering Task Force (IETF). IMS has also been transformed through the ETSI vision for Next Generation Networks with their TISPAN reference architecture. IMS has also been evolved for cable networks and MSO companies through the work of Cable Labs and the PacketCable standards. Finally, Verizon has implemented a proprietary version of IMS referred to as A-IMS.
SDP and SOA environments complement IMS (and vice versa) as the latter provides the centralized control for application logic and the ability to offer blended multimedia services across all networks and devices. Anyone considering IMS must also have a SDP strategy and vice versa.
