EXFO Verifier Agent EVA - Network visibility solution

Since the EVA can run as a standalone application or in a Docker container, the solution is much less resource intensive than a VNF requiring a hypervisor environment. For most small edge devices (vCPE, thin CPE), which do not have an abundance of CPU or memory available, this can be a roadblock. As a lightweight application, EVA can be deployed in any device where service assurance is required, without placing significant demands on available resources.

The application can be preloaded onto the CPE before shipping to the customer, greatly reducing the cost of deployment and making any CPE capable of supporting SLA-based services if needed. Like all EXFO’s service assurance solutions, EVA provides a high-level of flexibility to fully support carriers in their transformation to virtualized networks, regardless of where they are in this transformation process.

Used as an active probe, EVA executes test sequences to measure end-to-end and segmented performance across all layers of the service. It provides an accurate view of delivered quality of service and experience.

EVA can combine multiple tests to accurately pinpoint degradation and faults in the transport, service, infrastructure and application layer, accelerating the troubleshooting of faults and isolating potential issues. Tests include throughput, TWAMP, L2/L3 QoS test, IP services, Internet performance, SIP VoIP.
