Software Defined Wide Area Network (SD-WAN) is a network capability for routing traffic that decouples the networking hardware from the software controlling mechanism. In November 2018 Oracle completed the acquisition of Talari, the original innovators of failsafe SD-WAN technology and the leader in offering carrier-agnostic, failsafe SD-WANs. Talari have now become Oracle Communications Failsafe SD-WAN and are aimed at organisations that have mission-critical, real-time applications including VoIP, desktop virtualisation (VDI) and web/video conferencing that require high availability and predictable performance.

Use cases

Delivering critical VoIP services
Challenge – Requirement to deliver platinum VoIP quality across WAN services between regional emergency services locations, where WAN comprises private and public services of varying quality.
Outcome – Following deployment of SD-WAN appliances at critical locations, no VoIP sessions have been lost (or experienced service impacting VoIP quality issues) between regional emergency services locations.

Delivering optimal performance and reliability
Challenge – Requirement to deliver optimal performance and reliability for all applications accessing data-centre resources, fully utilise varied WAN services in all global locations, deliver central provisioning, updating and troubleshooting of WAN services, and provide verified security architecture for data across the SD-WAN.
Outcome – SD-WAN offered both instant failover and full-time bandwidth utilisation across all WAN services. Bespoke apps, document management and data back-up could use all available WAN bandwidth and VoIP / RDP applications get priority access to best available WAN services.

Delivering VoIP and bespoke manufacturing applications suite across global corporate WANs
Challenge – Requirement to deliver VoIP and bespoke manufacturing applications suite across global corporate WANs. Significant VoIP / video-quality issues causing business impact. Data back-up needs to run overnight due to lack of available bandwidth.
Outcome – Increased WAN capacity, improved network resiliency and lowered costs. Phone calls and videoconferences are loud and clear. No VoIP / video-quality issues. Bespoke business applications are speedy and unimpeded by network congestion or link failure.

Delivering optimal voice and video services for non-static locations
Challenge – Requirement to deliver high bandwidth, resilient, secure services over mobile IP networks. Need uninterrupted voice and video across multiple LTE/4G/satellite service providers.
Outcome – Optimal voice and video services delivered across available WAN services. Visibility of network service quality and bandwidth utilisation across all services. Visibility of application health across available services.
