Sandvine Policy Engine
Take Control of Your Network by Linking Conditions to Actions in Real-Time
The Sandvine Policy Engine is the brain of our platform, and is the foundation of all of our policy control solutions. It lets you realize your business objectives by linking any set of conditions to any set of actions, in real-time.
Information about measured conditions and provisioned subscriber entitlements flows into the Policy Engine, and charging updates, management actions, and business intelligence data emerge.
SandScript and DevOps
The Policy Engine is driven by a highly-configurable policy language called SandScript. Much more than a simple rules system, SandScript lets operators programmatically define and associate an infinite set of policy statements, any of which can affect a particular entity, such as a subscriber, in a specific context.
Changes made within the guiding SandScript ‘instructions’ become immediately active (i.e., live in the network)—making SandScript the perfect tool for the DevOps environments that are becoming increasingly common in CSP organizations.
Unified Policy Control
In Sandvine’s complete platform architecture, the Policy Engine operates in the data plane, within the Policy Traffic Switch (Sandvine’s PCEF/TDF), and in the control plane, within the Service Delivery Engine (Sandvine’s PCRF), and interacts with the B/OSS plane and remote enforcement points using industry standards. This unification across the control and data planes delivers many benefits:
Network operators define a policy once, and it is seamlessly and consistently applied across control and data planes.
Control signaling and the load on PCRF elements are significantly reduced, since decisions are made within the data plane whenever possible.
Policy decisions and actions are made faster by using a combination of many conditions and actions, by making many decisions concurrently, and because locally made decisions within the data plane don’t need to wait for a request and response from the PCRF.
The control and data planes have a common model of network policy control, so they have an equivalent understanding of what the business policy means and how it is implemented.

Network Policy Control: Methods and Considerations
Network policy control is an indispensable technology for ensuring the efficient and effective delivery of Internet data services. Communications service providers (CSPs) use network policy control to enable a wide variety of solutions across a broad range of functions. With so many factors in play, CSPs have much to consider when determining the best approach to policy management for their network.
This paper explores how CSPs can benefit from the convergence of compatible features in supporting desired use cases with minimal overhead.
