Unified Network Policy Control Using 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 from our traffic classification technology, and
- out of which charging updates, management actions, and business intelligence emerge from our powerful freeform policy language, SandScript.
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
