Case Study: a cloud service provider achieves vCPE performance visibility with Spirent Communications

Global Telecommunications Service Provider - Customer Case Study

The global telecommunications service provider was evaluating vendors for its SD-WAN and vCPE solutions and faced the daunting challenge of policy validation and performance benchmarking. This was particularly complex due to the multitude of service types with varied SLA requirements and the need to test in a multi-vendor, shared NFV environment. To address this, they engaged Spirent Communications to benchmark a vRouter VNF deployed in an OpenStack and KVM environment.

Spirent implemented its comprehensive NFV test solution to provide performance benchmarking. The solution delivered critical insights by correlating test traffic metrics with NFVi resource utilization data, which identified key performance bottlenecks and characterized VNF performance under various workloads. As a result, the service provider was able to reduce root cause analysis time by up to 80%, gain the intelligence necessary for proper resource allocation and vendor selection, and ultimately lower the total cost of ownership for their NFV deployment.
