ADDING MULTIMEDIA Ixia Tests Energy Efficiency in Independent Lab Test

Broadband-Testing Labs Validates Power Consumption of D-Link
Switch with Ixia's IxGreen Solution
CALABASAS, Calif.--(Business Wire)--
Ixia (NASDAQ: XXIA), a leading, global provider of IP performance
test systems, today announced its industry-leading IxGreen(TM)
Proof-of-Concept testing solution was used by Andorra-based
Broadband-Testing Labs to determine the energy efficiency of layer 2,
IP network switches from D-Link.

The energy-efficiency tests performed by Broadband-Testing Labs
involved D-Link's line of Enterprise-level 24-port, X-Stack DGT-3627,
DGT-3426 Layer 2/3 Gigabit Ethernet switches and the "Web Smart"
24-port, layer-2 DGT-1224T Gigabit Ethernet switch from D-Link's
"Green Ethernet" range. Testing was conducted at Ixia's test labs in
Marlow, U.K.

"In all three cases we were very impressed with the low levels of
power consumed, which were significantly below published class
averages," said Steve Broadhead, founder and CEO of Broadband-Testing
Labs. "Using Ixia's IxGreen solution, we were able to measure power
consumption with a wide range of different loads - from zero to wire
speed across all ports - and with different traffic profiles. In this
way we were able to generate a truly real-world set of meaningful
power consumption figures."

The maximum power consumption was 50.35 watts, recorded with
traffic running into the DGT-3627 and through the 10Gbps uplink into
the DGT-3426 - essentially an absolute maximum load. Meantime, the
"green" DGT-1224T, consuming a mere 9.3 watts in 10/100 idle mode,
maxed out at 23.65 watts when fully loaded at Gigabit line speed.

Broadhead concluded: "This means that per gigabit of traffic, the
switch consumed just 0.4 watts. The maximum power consumption recorded
was a truly excellent figure for a 24-port gigabit switch running line
speed with a 10Gbps uplink. The 'green' switches lived up to their
billing. We were also indebted to Ixia for the use of its integrated
traffic generator and power measurement tool in Ixia's
state-of-the-art, UK-based test facility," he said. "Ixia's IxGreen
proof-of-concept solution is the first such integrated
performance-per-power solution in the industry and one we are looking
to help drive standards-based testing for power consumption in the
industry."

"These test results prove that our switches can meet customers'
need to consume less power and save money while serving their business
interests," said Nigel Moulton, vice president of Enterprise and SME,
D-Link Europe. "The switches' low power consumption has a positive
multiplier effect on a data center's carbon footprint."

The IxGreen Proof-of-Concept solution was first demonstrated at
Interop Las Vegas in May 2008. IxGreen offers accurate and repeatable
validation of individual data center elements, with the emphasis on
performance and power consumption -- thereby enabling data center
managers to achieve their eco-efficient data center goals. These
goals, in addition to cooling and power savings, include consolidation
of data center elements, server and software virtualization, remote
management/administration and a reduced carbon footprint.
