NetScout® Systems, Inc. today announced that Tolly Group, an independent provider of third-party testing and validation services for the IT industry, has tested and certified the performance claims of the recently announced nGenius® 3900 series packet flow switch and nGenius PFS Management software. In their validation testing, Tolly Group evaluated the nGenius switch key characteristics, including throughput, latency, packet loss, feature functionality and ease of overall provisioning and system management. Test results highlighted in the report show the nGenius 3900 series switch delivers 100 percent line rate throughput along with sustained ultra-low latency and zero packet loss in all instances. In the report, Tolly also validated that the nGenius PFS Management software has an intuitive, drag-and-drop GUI that accelerates the setup and simplifies the management of hundreds of connections across a multi-chassis nGenius 3900 series deployment. The Tolly Group report is available on the Tolly Group web site and may also be accessed at www.netscout.com/tolly-pfs.

“Our test results validate that the nGenius 3900 series packet flow switch provides the scale, performance, intelligence and flexibility to construct seamless large-scale network monitoring fabrics,” said Kevin Tolly, founder of the Tolly Group. “In our testing, we validated that the nGenius 3900 series switch works as advertised. Our testing concluded that the platform provides full feature support on every port, including aggregation, filtering, load balancing and source port tagging with consistently low and deterministic latency across connections and features. We measured latency for both 10 Gigabit Ethernet (GbE) and 40GbE configurations and witnessed feature support that worked seamlessly on a single module, as well as between modules, within a multi-module chassis system. Further testing validated that the nGenius 3900 series switch delivered line-rate performance with zero packet loss when aggregating, filtering and load balancing traffic at up to 1.44 Tbps of tested full-duplex traffic. In addition, our testing confirmed that the nGenius PFS Management software provides seamless and consistent management and provisioning for multiple nGenius 3900 series switches that simplifies and automates management for large-scale, multi-location network monitoring deployments.”

“The nGenius packet flow switch provides us with the flexibility, scale and intelligence needed to support our high-demand network monitoring environment,” said Peter Burke, Telecommunications Engineer at Hydro-Québec, a world leader in hydropower. “We have already taken advantage of the nGenius 1500 series packet flow switch’s powerful aggregation and intelligent filtering capabilities to maximize our investments in our nGenius InfiniStream® appliances and other management and security tools. We are encouraged by the increased port density, consistent features performance and new levels of capacity that the nGenius 3900 series packet flow switch can deliver. We believe this new switch is a good extension to NetScout’s product line and could further improve our ability to address the growing number of high-speed network connections.”

The nGenius 3900 series packet flow switch delivers market-leading advances in performance and capacity with the highest 10 and 40GbE port densities per rack unit, and per chassis, with an architecture ready to support 100GbE interfaces. The nGenius 3900 series switch is built from deployment-proven data center-class switching technology and leverages a common high-density interface module that provides local switching and packet processing capabilities that can be seamlessly interchanged across the chassis series. The nGenius 3900 series packet flow switch can scale to support up to 5.76 Tbps full-duplex (11.5 Tbps aggregate) switching capacity and supports from 16 to 576 ports of 10GbE and up to 48 ports of 40GbE in a single chassis.

“As enterprise and service provider organizations build highly scalable monitoring fabrics, they need high-density network monitoring switches that deliver the performance, capacity and flexibility to scale access to packet-flow traffic without having to make trade-offs between interface density and feature performance,” said Steven Shalita, vice president, marketing, at NetScout. “A network monitoring fabric needs to be seamless and transparent to deliver performance at scale and should not introduce unnecessary latency or impede performance that negatively impacts the integrity of traffic measurements. The testing performed by Tolly Group provides independent validation of the technological strength and performance levels of the nGenius 3900 series packet flow switch and provides confidence about the platform’s ability to support large-scale monitoring fabrics.”
