Case Study: a tier 1 U.S. service provider achieves SD-WAN readiness and millions in savings with Spirent SD-WAN Underlay Assurance

MSO Prepares for SD-WAN with Automation and Virtual Active Testing

A tier 1 U.S. service provider faced significant challenges in scaling its enterprise services following a merger. Its legacy systems provided no visibility into the performance of its layer 3 IP services and its manual, file-based processes were slow and costly. The provider engaged Spirent Communications to build a foundation for future SD-WAN services and to automate service activation and troubleshooting while ensuring quality.

Spirent implemented its VisionWorks Active Assurance solution, deploying Virtual Test Platforms (VTPs) and Virtual Test Agents (VTAs) to over a thousand points of presence. This provided immediate visibility into layer 3 performance and automated key workflows. The Spirent solution resulted in over $10,000,000 in CAPEX savings by replacing hardware probes, millions in annual OPEX savings, and eliminated SLA violation penalties, while also future-proofing the network for SD-WAN and virtualization.
