One of the recently most talked about topics within the Telecom/IT industry community is the subject of Service Delivery Platforms (SDPs). These platforms aim to enable Telecom operators to provide a complete environment for creation, deployment, execution, management and billing for a wide range of value added content and services. Services deployed using these platforms will be agnostic to the underlying network technology. This requires a new, more flexible, architecture and a common communication framework that will support interoperability. A promising approach to this is to use a Service Oriented Architecture (SOA). SoA is a software architecture involving loosely coupled, location independent services generally using the so-called "find-bind-execute" paradigm for the communication between SOA service providers, SOA service users and a SOA service registry. An essential characteristic of an SOA is that it provides published contract-based, platform and technology neutral service interfaces. This means that the interface of a service is independent of its implementation. In this paper the principles of the Service-Oriented Architecture are described, as well as the relationship between the Enterprises and SOA. The potential benefits of SOA, its relevance and its limitations to a Telco are also discussed. The document is most useful for CIO-s, IT technology and business management specialists.
