The Service Delivery Platform (SDP) represents an entirely new approach to deploying enhanced services in IMS–enabled, converged TDM/ IP and end–to–end VoIP carrier networks. Its open architecture and innovative use of next–generation network standards—including SIP, IMS, VoiceXML, MGCP and XML—provide a multi–service platform with tremendous flexibility and scalability.
Radisys provides a complete solution for deploying revenue–generating IP voice communication services in converged TDM/IP and end-to-end IP packet networks. Based on our open, extensible and highly scalable Radisys Application Server and Radisys Media Server, the Radisys hosted communications solution includes an expanding suite of turnkey SIPware services—or create your own innovative services using the Radisys Service Creation Environment.

Key Service Delivery Platform (SDP) Benefits
- Supports multiple hosted SIPware services running side–by–side on industry standard hardware.
- Enables rapid integration with any service provider network—pure IP or converged TDM/IP, wireless or wireline.
- Accelerates development of new applications and features with our industry–leading Service Creation Environment and standards–based software architecture.
- Permits graceful, linear scaling to support up to millions of wireless subscribers and billions of minutes—with carrier–grade performance and reliability.
- Delivers carrier–grade reliability and performance—with “five–nines” availability.
- Enhances flexibility, enabling carriers to evolve their IP service architecture quickly and cost–effectively.
- Reduces costs—as a pure IP solution, the SDP eliminates costly TDM switches, dramatically reducing capital and operational costs.
The Radisys SDP represents a comprehensive service delivery solution, comprising both Runtime and Development Time software components. With Radisys, service providers have a single, flexible, highly-scalable solution for delivering customized, hosted services with proven subscriber appeal. SDP components include:
Application Server
Based on a pure IP design and running on industry-standard Linux hardware, the Application Server acts as the intelligent controller of switching, gateway, session control and media server resources. At its core is a high-performance Service Logic Execution Environment (SLEE) built using XML-based scripts. XTML adds an openly published XML schema that includes tags that enable the Application Server to perform third-party call control. Service applications are represented as XTML files, where every call is an Application Server session running XTML logic.
Designed for high volume, high-performance carrier networks, the Application Server can run up to 7,000 concurrent call sessions on a single Linux system, or scale to extremely large call handling capacities by configuring multiple servers.
The SDP also features Radisys CallComplete, which allows call session states to be transparently duplicated in real time, protecting calls in progress in the event of an Application Server failure.
Service Creation Environment (SCE)
The SCE is an industry-leading visual service development environment that enables developers to build sophisticated NGN applications easily using drag-and-drop Plug-in Action Components (PACs) to enable various built-in operations, linking them in a visual call flow. This simple, intuitive interface makes applications faster to develop, customize, and modify to meet changing market needs.
Software Development Kit (SDK)
The SDK is a software development kit that allows third parties to create their own PACs that extend the software framework of both the Application Server and the SCE, allowing developers to extend the capabilities of the SDP to add new protocols, APIs or custom features for their market specific applications.
Session Border Controller
The Session Border Controller provides access network NAT Traversal and SIP endpoint registration for SIPware Voice over Broadband (VoBB) deployments where the subscriber’s VoIP endpoint device is behind a local firewall on premise.
Network Interface Unit (NIU)
The Network Interface Unit acts as a stateless SIP proxy configured to receive incoming SIP network requests and hand them off to an available Application Server. In this role it serves two primary functions: 1) load balancing call traffic among all available Application Servers based on available capacity; and 2) monitoring continuous status of the Application Servers to detect failure conditions and route new call requests to the remaining Application Server clusters.
System Management Console
This Java-based GUI console provides platform operators with a single unified interface to all runtime software components of the SDP for all system configuration, operation, and monitoring tasks.
