Cloud and Virtualization Overview
In the migration of applications to private and public Cloud environments, Network Function Virtualization (NFV) is being adopted as one of the most disruptive changes in telecommunications since the transition to all-IP networks. NFV focuses on new methods for deployment and delivery of telecom services over a software-based network infrastructure. Through NFV, applications that were previously coupled to proprietary hardware can now be virtually instantiated on generic commercial off-the-shelf (COTS) computing hardware.
With NFV and service orchestration, cloud service delivery models are rapidly changing real-time communications (RTC) with new dynamic services and anticipated cost efficiencies….and anything less should be considered a failure. Trying to figure out how the Cloud will optimize your RTC service delivery models from today’s proprietary, complex and disjointed solutions can be confusing. As there are numerous challenges in transitioning RTC in the Cloud, many promises are being made for how to effectively deploy and operationalize cloud-based RTC.
To avoid false promises (cloud myths) and to clarify what cloud reality looks like, turn to Sonus. By leveraging a common codebase across hardware and software-only solutions, Sonus provides a migration path to private and public clouds that can begin at multiple points within a network. Yet Sonus is doing more than just porting SBC software to the Cloud, instead Sonus has optimized its portfolio to deliver more value in the Cloud.
Virtual CPE (vCPE)
This emerging market is based on leveraging the value of NFV for network edge services at the customer location. This is a perfect application for Sonus’ virtualized SBC. Virtual CPE deployment models could include a cloud-based service provider offering SBC-as-a-Service, service provider-owned virtualized SBC deployed as managed CPE, or an enterprise-owned virtualized SBC deployed on customer premise.
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. Cloud-based Unified Communications, Conferencing, and Contact Center service providers will deploy virtualized access SBCs and provide value added services such as encryption and interworking without sacrificing performance, quality or capacity.
Virtualized Interconnect SBCs
With NFV and orchestration, service providers will take advantage of cloud elasticity for scaling. With automated, on-demand instantiation and configuration of virtual SBC resources, service provides can dynamically match (increase or decrease) SBC capacity to traffic demand at service provider interconnection points. With a virtualized interconnect SBC, as load dynamically changes and as virtual instances are established or removed, the important underlying attributes of reliability, load balancing, and performance are all handled flawlessly.
Virtual SBC Microservices
Microservice refers to a style of application development where components are created that are each designed to run relatively independently. Sonus’ SBC SWe has adopted a microservices architecture to become more cloud-optimized. The SBC SWe can now be separated into VNFs for Signaling Services: security and protocol interworking for the SIP session; Media Services: security, Quality of Service (QoS) control, Network Address Translation (NAT) traversal, port firewalling and bandwidth policing; and Transcoding Services: transcoding, transrating, DTMF tone detection/interworking, and RTCP reporting.
Virtualized Policy Control
Sonus expanded its cloud-optimized portfolio to now include the Centralized Policy and Routing Engine (PSX) and Element Management System (EMS. With this addition, a service provider can dynamically instantiate virtual policy & routing control and virtual session management. This means a common service orchestration system can easily service chain virtual policy control and virtual session management providing the ability to align virtual network resources for routing, security, interworking and quality assurance of real-time communications.
Management and Orchestration
Sonus supports standard OpenStack and ETSI-based interfaces and partnerships with market-leading service orchestration and VNF infrastructure vendors to facilitate VNF instantiation. Sonus continues to expand our partnerships to align with our customer implementation choices. In addition, Sonus supports SBC SWe in Amazon Web Services. For service providers requiring a more turn-key and integrated solution, Sonus can provide its own VNF Manager using the Sonus Element Management System.
