Cloud and Virtualization Overview

Network Functions Virtualization (NFV) and service migration to the Cloud are being adopted as the most disruptive changes in telecommunications since the transition to all-IP networks. NFV enables new methods for deployment and delivery of real-time communication services using a software-based network infrastructure, so applications that were previously coupled to proprietary hardware can now be ­­­instantiated on generic commercial off-the-shelf (COTS) computing hardware in Cloud environments.

Sonus has optimized its SBC SWe for cloud deployments, allowing service providers and enterprises to break free from propriety hardware and truly unleash real-time communications in the Cloud. With our heritage of enabling secure, reliable and scalable real-time communications, beginning with the transition from TDM to IP and now into the Cloud, Sonus provides a clear migration path to private and public Clouds that can begin at multiple points within a network.

Multiple opportunities exist to take advantage of NFV and Cloud-deployments for the Sonus Session Border Controller (SBC), including:

Virtual CPE (vCPE)

By leveraging network functions virtualization (NFV), Communication Service Providers (CSPs) can provide virtual customer premises equipment (vCPE) solutions, which reduce the number and cost of physical SBC hardware appliances required at the customer premises for SIP Trunking and other real-time communication services. By deploying a smaller number of generic commercial off-the-shelf (COTS) computing hardware platforms either locally at the customer's premises or in a centralized data center, CSPs can remotely instantiate, configure, and manage a variety of features and functions that were once deployed on dedicated hardware platforms.

Virtualized Access SBCs

Sonus’ cloud-optimized SBC delivers key feature functionality designed to ease a service provider’s migration of real-time communications to the Cloud. With Sonus’ cloud-optimized SBCs, service providers can dramatically increase their customer responsiveness by being able to bring up run-time ready SBCs for secure, robust, SIP service in just minutes. Access service providers for cloud-based Unified Communications, Conferencing, and Contact Center services can virtualize their SBCs into the Cloud and provide value added services such as encryption and interworking without sacrificing performance, quality or capacity.

Virtualized Interconnect SBCs

Sonus is moving past virtualization and supplying service providers with a true, software-only SBC optimized for Cloud deployments. Sonus’ SBC SWe is the only SBC in the marketplace architected to enable and secure real-time communications in the Cloud without compromising on performance or scale. From auto registration and auto configuration to innovative load balancing and management, Sonus’ cloud-optimized SBC speeds up interconnect service delivery and maximizes operational efficiency.

Management and Orchestration

As customers move beyond single instance virtualization to a full Cloud implementation, support for standards based interfaces and an orchestration ecosystem becomes increasingly important. Sonus SBC SWe supports standard OpenStack and ETSI-based interfaces combined with a wide ecosystem of market-leading orchestration vendors to facilitate Virtual Network Function (VNF) implementations. In addition, for service providers requiring a more turn-key and integrated solution, Sonus can provide its own VNF Manager (VNFM) using the Sonus Element Management System.
