WESTFORD, Mass. -- January 30, 2013

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

“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

“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.”
