Dynamic Diameter Engine (DDE)

Get ready for the next generation of Diameter Signaling Control use cases with DDE

Improve signaling plane efficiency, security, and performance with the Nokia Dynamic Diameter Engine (DDE).

Our multivendor product lets you simplify and manage signaling plane traffic. We combine innovative rules engine technology with our deep Diameter expertise to give you an effective toolkit for addressing rapid signaling traffic growth. With DDE, you can streamline your control plane operations, reduce outages, and deliver a better quality of experience.

Data service demand ramps up Diameter traffic

Diameter-based control plane traffic is escalating as consumers embrace advanced mobile broadband services. This growth results in an increasingly complex control topology and creates inefficiency and unpredictability.

To deliver the rich, secure experiences your customers want, you need an intelligent product that brings greater flexibility to the signaling control plane.

Why choose Nokia for Diameter control?

Built for virtualization

DDE offers deployment and configuration options that address a variety of service provider requirements. These options include virtualized commercial off-the-shelf configurations that give you more flexibility and scale and help you reduce the cost of introducing new capacity.

Agile Rules Technology

DDE is based on our Agile Rules Technology (A.R.T.). Backed by more than 150 patents, A.R.T. provides ease of use, flexibility, high performance, scalability, and maintainability. With A.R.T. you can:

  • Simplify the creation, testing, and deployment of Diameter routing policies with an easy-to-use visualization interface
  • Address your exact needs with a flexible, wide-ranging collection of Diameter routing use cases
  • Deliver high performance on any scale with policies to control complex Diameter routing scenarios
  • Streamline installation, upgrade, operations, and troubleshooting processes with service provider-centric technology

Extensive Diameter experience

DDE draws on our deep knowledge of the Diameter protocol. We develop the Diameter capabilities of our packet core, IMS, and policy and charging control solutions in house. Our products are designed to work successfully in any multivendor environment. We have used our experience to help dozens of service providers around the world with their specific Diameter routing needs.

Get smart about Diameter signaling

Our DDE product helps you address the challenges of signaling plane traffic growth.

Simplify your control topology

Reduce complexity by migrating to a simplified control topology. With Diameter routing agent (DRA) functionality you can create a hub-and-spoke topology that gives you more flexibility to define control plane behavior and support advanced mediation capabilities.

Manage control plane behavior

Boost operations efficiency, scalability, and performance by defining behavior in the control plane. DDE lets you create routing policies that enable and simplify Diameter server selection, load balancing, and session management.

Ensure interoperability within the control plane

Add Diameter control elements without worrying about compatibility issues. With our DDE you can leverage mediation and data manipulation capabilities to ensure interoperability across different element versions and vendor implementations.

Secure the roaming infrastructure

Control and protect the exchange of signaling information across the roaming infrastructure with our Diameter edge agent (DEA) functionality, which lets you:

  • Control complex roaming agreements
  • Hide the network topology
  • Fix key message content and filter out unwanted data


The Nokia Dynamic Diameter Engine (DDE) helps service providers easily and quickly develop customized policies to accommodate increases in signaling control plane traffic. The result is a simpler, more scalable, and more secure control topology. Designed for virtualization, DDE combines our innovative rules engine technology with our deep Diameter expertise. It provides an effective solution for addressing rapid signaling traffic growth, along with the deployment flexibility and scalability that service providers need.
