Sonus advances virtualisation offerings to make communications networks more flexible, cost-effective

Software Editions of Sonus’ Centralised Policy and Routing Engine, and Diameter Signaling Controller deliver the same exceptional performance and functionality as hardware

October 2, 2014

Key Takeaways:

  • Sonus executes the next step in its multi-phase virtualisation strategy with the introduction of the Sonus PSX SWe (Software edition) and the Sonus DSC SWe—virtualised platforms of Sonus’ PSX Centralised Policy and Routing Engine, and Diameter Signaling Controller (DSC).
  • Sonus is the only brand on the market to leverage a common, hardened code base across its hardware and software portfolios for core communications networks, providing customers holistic investment protection.
  • The Sonus PSX SWe and DSC SWe address service provider and enterprise requirements for network functions virtualisation (NFV) and software-defined networking (SDN) enabled technology to scale Cloud-based delivery platforms for real-time communications.
  • All of Sonus’ virtualised platforms will interoperate with the Juniper Networks® Contrail controller for SDN and NFV.


Sonus Networks, Inc. (Nasdaq: SONS), a global leader in enabling and securing real-time communications, today announced the next milestone in the company’s strategy to virtualise its product portfolio with the introduction of the Sonus PSX SWe (Software edition) and the Sonus DSC SWe.

By virtualising communications networks, service providers and enterprises can dramatically reduce the time, risk and expense of introducing new services. The portability and flexibility of the PSX SWe—Sonus’ virtualised PSX Centralized Policy and Routing Engine, and the DSC SWe—Sonus’ virtualised Diameter Signaling Controller (DSC), make them the ideal choice for service providers and enterprises seeking virtualisation technology, prefer pre-packaged “solutions in a box,” require remote network deployments or want to expand opportunities into new geographic markets where deploying a hardware solution would be impractical or cost prohibitive.

Building upon its strategy to virtualise the field-proven code base of its industry-leading hardware platforms, Sonus customers can now seamlessly and flexibly deploy the PSX SWe and the DSC SWe software platforms into networks using commercial-off-the-shelf platforms. For customers looking to leverage new and existing platforms to support network functions virtualisation (NFV) functionality, the PSX SWe and DSC SWe allow customers to deploy a fully-featured policy engine or DSC co-resident with other applications.

In addition to the PSX SWe and DSC SWe, Sonus’ portfolio of virtualised solutions includes the SBC SWe—the industry’s first software-based Session Border Controller (SBC) architected to deliver user defined scalability with the same advanced features and functionality as hardware. Starting with the SBC SWe, Sonus’ virtualised software will interoperate with Juniper Networks’ Contrail SDN and NFV platform, which offers a secure, scalable, multi-tenant and carrier-grade environment in which network functions can be provisioned and orchestrated in an automated fashion. This platform is designed to simplify the way service providers deliver differentiated Cloud-based Unified Communications (UC) and video experiences to enterprises. This solution empowers service providers to offer a range of innovative new services, including same-day Session Initiation Protocol (SIP) trunking services in new markets and geographies, scale of SIP capacity anywhere in the network and delivery of high-end SIP services at a lower price point to small and medium businesses.

Designed to be “gold standard” in network policy and routing management for service providers and enterprises, Sonus’ PSX Centralised Policy and Routing Engine 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 PSX SWe provides the same features, exceptional scalability and centralised policy/traffic control as hardware for today’s modern wireline and wireless networks, including Session Initiation Protocol (SIP), 4G LTE as well as legacy network elements including media gateways and soft switches. For Sonus customers, the PSX SWe delivers a wide range of real-world benefits, including intelligent routing, simplified network management, lower cost and increased margins for delivering real-time communications such as Voice over LTE (VoLTE), Voice over Internet Protocol (VoIP) and video calls.

The demand for 4G/Long-Term Evolution (LTE) networks is projected to grow exponentially as mobile broadband demand for smartphones and tablets, and diameter-signaling messages in 4G/LTE networks grows correspondently. The Sonus DSC is a flexible, robust, carrier-grade solution to solve the diameter routing dilemma, and the DSC SWe provides all functionality required for both core and edge diameter routing within the all-IP, service-oriented, IMS and LTE networks. The DSC SWe offers customers the most nimble approach to scale deployments from proof of concept to production solely by adding licenses as needed.


“SDN and NFV are key components of our strategy, and we are committed to delivering seamlessly interoperable network solutions for our global service provider customers. By partnering with Sonus, we can now offer a solution to empower service providers by delivering a range of new advanced services, including a software-defined solution that automates and orchestrates the creation of highly scalable virtual networks and delivers real-time services,” said Jennifer Lin, senior director of product management, SDN, Juniper Networks. “We look forward to continuing our partnership and delivering innovative solutions with Sonus.”

“The advent of virtualisation technologies has radically changed how service providers and enterprises introduce new features and services,” said David Tipping, vice president and general manager, Products, Sonus. “Sonus is committed to leading the way in delivering the flexibility and capability of virtualisation so customers can simply and effectively deploy fully-featured SBCs, policy and routing management and diameter signaling controllers.”

“Service providers around the globe are moving toward SDN/NFV; it is a fundamental change in network architecture that will deliver benefits in new services and revenue, operational efficiency and CapEx savings. However, to take advantage of these opportunities, operators need access to virtualised solutions with the same high performance and security as hardware,” said Diane Myers, principal analyst, Infonetics Research. “Sonus’ approach to virtualisation is delivering security, voice and video quality, centralised policy management and broad interoperability features to enable customers to migrate their networks to NFV.”

Other Facts:

  • According to the Infonetics Research report, “SDN and NFV Strategies: Global Service Provider Survey,” bandwidth-on-demand topped the list for new revenue generating opportunities in SDN/NFV environments, closely followed by dynamic policy and pricing.
  • Sonus’ SBCs have received wide industry recognition, including the Gold Award in the Product Line of the Year category of the Best in Biz Awards 2014 EMEA, the 2014 Unified Communications Product of the Year and 2014 Excellence in SDN award.
  • Sonus was positioned in the Leaders Quadrants of the “Magic Quadrant for Session Border Controllers,” published October 21, 2013 by Gartner, Inc.
