Case Study: a major retailer company saves on SD-WAN costs with Spirent Network Emulator

Major Retailer Company - Customer Case Study

The customer, a major retailer, faced significant network congestion after transitioning from MPLS to a more cost-effective SD-WAN, which degraded their VoIP service quality. To avoid a costly service upgrade, they engaged Spirent Communications and implemented the Spirent Network Emulator to identify performance thresholds.

The Spirent solution allowed the retailer to test and establish the precise latency, loss, and jitter limits for acceptable VoIP calls. By integrating these metrics into their provider's SLA and switchover policies, the retailer maintained their existing service level without the planned $120k annual upgrade, resulting in substantial savings.
