Sandvine Virtual Series: Overview Supporting industry and open standards, the Sandvine Virtual Series delivers Sandvine’s powerful Policy Engine, PCEF/TDF, and PCRF as elastically-scalable virtual network functions for SDN- and NFV-ready networks Communications service providers (CSPs) are continually looking for ways to increase efficiency and deliver rich new services through the carrier cloud, and for those reasons many are exploring the promise of software-defined networking (SDN) and network functions virtualization (NFV). • SDN seeks to separate the data plane and control plane in all networks, and to have any linkage/paths between network functions be defined by software, on-the-fly, via APIs. SDN is a deployment tool that enables a programmable network. • NFV is a carrier-led effort to move away from proprietary hardware, motivated by desires to dramatically reduce the cost of deployment by using standard x86 commercial off-the-shelf (COTS) hardware for everything. Running all functions on identical, shared hardware promises a much simpler, more efficient network. For Sandvine and our customers, virtualization technology extends our network policy control deployment options, enabling exciting new use cases and extending our proven solutions to new environments. The Sandvine Virtual Series enables CSPs to enjoy all the features of the traditional Sandvine platform while benefiting from the elasticity and efficiency of running virtual machines on off-the-shelf hardware. With this model, deployments scale up or down as needed, in lock-step with demand. Deployment Versatility through Openness and Standards Support The Sandvine Virtual Series provides hassle-free integration with standard SDN and NFV architectures: • Fully virtualized and interoperable with OpenStack™ • Proven integration with industry leading virtual platforms, including Juniper’s Contrail™ • Partnerships and program membership with other leading companies, including: Intel™, Alcatel-Lucent CloudBand™, Dell, and Red Hat “To compete in the marketplace, it is critical for regional carriers to have access to the same advanced technology as national carriers. We have incorporated Sandvine’s virtual PTS platform into our Total Traffic Manager (TTM) solution, so our regional carriers will have access to the most advanced Policy Control services in the Cloud with minimum capital expense. Rolling new services to increase ARPU and managing the rapid growth in data traffic just got easier.” - Dean Fresonke, Senior Vice President of Business Development Sandvine platform components running in the OpenStackTM environment TECHNOLOGIES Deploying the Sandvine Virtual Series 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. 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: • The Policy Traffic Switch (PTS): 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 ultraintelligent PCEF/TDF that scales to meet the demands of the world’s largest networks. Virtualized networks use the PTS Virtual Platform (PTS VPL); more information is available in Policy Traffic Switch Virtual Series: Datasheet. • The Service Delivery Engine (SDE): 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. Our architecture also includes the Subscriber Policy Broker (SPB), which is an embedded database that provides long-term storage for comprehensive business intelligence insight, without requiring any database administration. In a virtualized network, Sandvine’s platform elements deploy as Virtual Network Functions (VNFs) that scale independently; that is, the number of distinct PTS instances, SDE instances, and Subscriber Policy Broker (SPB) instances increase or decrease dynamically and separately in response to demand.
