Regarded as the “gold standard” in network policy and routing management for service providers and enterprises, Sonus’ Centralized Policy and Routing Engine (PSX) is the industry's most feature-rich policy and routing control platform, delivering unparalleled reliability in the world’s most demanding environments and scalability to millions of subscribers. The virtualized PSX SWe is cloud optimized and provides the same features, exceptional scalability and centralized policy/traffic control as hardware-based PSX for both SIP and legacy network elements, including SBCs, media gateways and soft-switches. For Sonus customers, the PSX SWe fits seamlessly into any service provider’s or enterprise’s Network Function Virtualization (NFV) strategy. Designed to be agile, the PSX delivers a spectrum of real-world benefits, including lower cost Voice over Internet Protocol (VoIP) and video calls, intelligent routing, centralized dial plan, simplified network management and increased margins.
For customers planning and designing cloud-based network architecture, the PSX provides support for OpenStack based service orchestration. In such a deployment scenario, PSX instances can be created and deleted on demand based traffic requirements.
