Sandvine Policy Engine
Unified Network Policy Control with the Sandvine Policy Engine
The Sandvine Policy Engine is the world’s most versatile and powerful network policy control platform, and is the foundation of all Sandvine solutions. Our Policy Engine can be thought of as a black box into which information about measured conditions and provisioned subscriber entitlements flow, and out of which charging updates, management actions, and business intelligence emerge.
Thanks to this versatility and power, the Policy Engine provides a single platform on which to introduce unified, standards-compliant network policy control into any fixed, mobile, or converged access network, whether the network is physical or virtual. This abstraction also makes the Sandvine Policy Engine a single mechanism by which communications service providers can express any past, present, or future network policy control use case.
Deploy in Any Network, with Any Combination of Access Technologies
The Policy Engine spans both the data plane and control plane, embedded within Sandvine’s PCEF/TDF and PCRF elements, and interacts with the B/OSS plane and remote enforcement points using standard interfaces. This unification across the control and data planes and the distributed intelligence that it brings delivers many benefits:
- 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 locally
- Policy decisions are made faster, without needing to wait for a query and response
- 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 is completely agnostic of access technologies and vendors within the network
Deploying the Sandvine Policy Engine
In Sandvine’s architecture, our Policy Engine is embedded in two elements to span the control and data planes:
Embedding Intelligence in the Data Plane for Maximum Performance
The PTS uses deep-packet inspection (DPI) technology to identify and measure traffic, relies on the Sandvine Policy Engine to make local policy decisions and apply enforcement actions, and provides real-time measurements and interfaces for online charging; put simply, the PTS functions as an ultra-intelligent PCEF/TDF that scales to meet the demands of the world’s largest networks.

Enabling Standards Compliant Policy Control in Multi-Access Networks
The SDE is a complete PCRF (including a 3GPP Release 11-compliant Gx interface) that also performs vital control plane functions including real-time subscriber provisioning and session mapping. Running virtually on standard servers, the SDE works together with the PTS to provide unified network policy control within multivendor and multi-access networks.

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.
