Assure virtualized Ethernet services

EXFO's Nova Virtual Active Agent (previously known as Virtual Verifier) enables service providers to deploy a verifier virtual network function (VNF) anywhere in the virtualized service chain to perform testing and then seamlessly evolve to real-time performance monitoring or vice versa—all with minimal capital expenditures. It leverages the flexibility of SDN/NFV, monitors the quality of those services and assures a high QoE for end users. With unprecedented test scalability to thousands of locations, Nova Virtual Active Agent ensures complete end-to-end SDN/NFV network visibility. Carriers can deploy Nova Virtual Active Agent using a third-party orchestrator to turn-up and assure multiple new circuits simultaneously and measure, in real time, the performance of data transport, wireless backhaul, metro Ethernet, VoIP, mobile and video services.

Benefits of virtualized probes

  • Reduce cost of deploying verifiers and expand the scope of deploying them in every service segment
  • Enable the full lifecycle of Ethernet/IP circuits by turning up, monitoring and troubleshooting them through a single VNF
  • Accelerate time-to-market by enabling fast deployment of assured services on demand
  • Reduce design-to-deployment time
  • Take advantage of an open system that is easy to integrate with SDN/NFV architectures 
  • Enable operational efficiency by fixing faults and introducing assured services in real time
  • Reduce OPEX and CAPEX by enabling a fully automated service delivery and monitoring lifecycle
  • Open up new markets and monetization opportunities
