RAD’s Ethernet performance monitoring solutions allow Carrier Ethernet service providers to manage network and service performance levels at all times, enabling them to offer their business and wholesale customers stringent SLA (service level agreement) guarantees. The RADview-PM Ethernet performance portal collects Ethernet service KPI (key performance indicators) data for real-time monitoring, while the EtherAccess EchoVault SLA delivery and Ethernet service monitoring systemprovides a service-centric end-to-end view of SLA performance per EVC.CoS (Ethernet virtual connection class of service) in large networks.
