Ixia to Demonstrate First Ever Mobile Network Testing with Real-World Triple-Play Traffic

Ixia (NASDAQ:XXIA), a leading global provider of IP performance
test systems, announced that it will demonstrate the first ever
real-world, triple-play testing for Gateway GPRS Support Nodes (GGSNs)
at the Mobile World Congress, February 11-14 in Barcelona. Ixia´s
IxLoad 4.10 application has been enhanced to test GGSNs, which are
part of the packet-switched core network in both 2.5G and 3G mobile
systems.

With increasing demand for broadband mobile data services,
operators require the ability to perform traffic engineering and other
functions based on the type of traffic traversing the network. GGSNs
now accomplish these functions using a process known as deep packet
inspection, or DPI, but testing them has become increasingly
challenging.

"Realistic triple-play traffic is necessary to be able to
accurately test the capability of the GGSN to inspect traffic and
differentiate between the different traffic types, in addition to
testing various other functions," said Stephane Teral, principal
analyst with Infonetics.

Infonetics reports that in 2005, 91.7 million mobile subscribers
were served over 3G W-CDMA networks. The company predicts that, by
2010, the number will grow to 522.1 million for a compound annual
growth rate of 41 percent.

"Up until now, manufacturers and mobile operators have had limited
ability to test GGSNs with stateful, that is realistic, triple-play
traffic, relying instead on less sophisticated traffic generation such
as bit-blasting," said Victor Alston, Ixia senior vice president of
Product Development. "With IxLoad, the mobile industry will be able to
emulate real-world traffic that provides the rigorous testing
required."

IxLoad can emulate thousands of triple-play (voice, video and
data) subscribers along with associated protocols. Manufacturers and
mobile operators use this capability to stress devices and networks in
order to accurately assess their performance.

Ixia will be demonstrating its Triple Play testing capabilities
Feb. 11-14 at its stand 1A03 in Hall 1 at Mobile World Congress in
Barcelona.
