SAN FRANCISCO, CA–( EMWNews – April 7, 2008) – Riverbed Technology

(NASDAQ: RVBD), the technology and market leader in

wide-area data services (WDS), announced today that the

National Satellite and Meteorological Center (NSMC), a

scientific research and operational facility affiliated with

the China Meteorological Administration, has selected and

deployed Riverbed® Steelhead® WDS appliances in its data

processing center and at three ground receiving stations at

locations across China. The deployment of the Riverbed WDS

solution gives NSMC faster access to satellite images and

allows NSMC to provide more accurate weather forecasts,

without costly bandwidth upgrades.

NSMC is China’s satellite weather monitoring, forecasting

and warning center and plays an essential role in weather

forecasting, natural disaster monitoring and subsequent

analysis of the impact of weather events and natural

disasters on the national economy. NSMC’s ground system

consists of three ground data receiving stations in

Guangzhou, Urumqi and Jamusi, together with a data

processing center in Beijing, which processes more than 300

GB of data in one day. Data from ground stations is

continuously collected and transmitted to NSMC’s data

processing center in Beijing.

Before deploying the Riverbed solution, NSMC’s Beijing data

processing center was connected to its other ground stations

through a 10MB WAN link. However, as the observation

capability of China’s weather satellite increased, WAN

traffic jumped one-hundred fold within a decade. The rising

role of satellites not only in weather forecasting, but also

in environment and disaster monitoring, exacts higher

requirements from weather satellite remote sensing and

ground stations alike, in turn exerting tremendous pressure

on NSMC’s wide area network (WAN).

“With Riverbed, we can now fully optimize our WAN bandwidth,

which ensures stable and reliable performance, while

harnessing the full power of our technology resources

through acceleration of our data-rich applications. Working

with Riverbed, we can now deliver all weather forecasts

faster so that millions of people have more lead time to

take action,” said Dr. Lin Manyun, from the Satellite

Operations Office of NSMC. “Additionally, in contrast to the

spiralling increased costs of expansion in bandwidth,

Riverbed Steelhead appliances bring us a higher return on

investment, enabling us to meet the demanding time-critical

data transfer objectives required for accurate weather

forecasting without costly bandwidth upgrades.”

“We are pleased that the National Satellite Meteorological

Center has selected Riverbed from among the WDS

alternatives. The Riverbed WDS solution is the industry’s

most comprehensive, supporting multiple protocols, different

configurations, and acceleration of the wide variety of

applications important to business. The Riverbed solution

alleviates multiple bandwidth bottlenecks simultaneously

while simplifying data management,” said Thomas Chin, vice

president of Riverbed Asia Pacific and Japan. “Today,

Riverbed has more than 3,500 customers around the globe.

Since our entry into the China market in 2005, we’ve focused

on our customers, facilitating collaboration between their

offices, and helping them to reduce IT costs. We intend to

maintain our commitment to providing WDS solutions that meet

the needs of our Chinese users.”

Dr. Lin commented on the selection of Riverbed Steelhead WDS

appliances: “Among the WDS products evaluated, the Steelhead

appliances offered the most complete solution, addressing

all aspects of WAN performance and accelerated more

applications and protocols than the alternatives. The

Riverbed product uniquely and dramatically improves the

throughput of our scientific applications. Unlike all other

products tested, the Steelhead appliances were quick and

easy to deploy and required no change to our existing

infrastructure. Finally, our user experience was

exceptional, with nearly all remote personnel commenting how

they now felt they were all operating within the same

location.”

Steelhead Products

The Riverbed WDS solutions enable organizations of all sizes

to overcome a host of severe problems, including poor

application performance and insufficient bandwidth at remote

sites. By speeding the performance of applications between

data centers, remote offices and mobile workers by five to

50 times and in some cases up to 100 times, Riverbed’s

award-winning Steelhead WDS products enable companies to

consolidate IT, improve backup and replication processes to

ensure data integrity, and improve staff productivity and

collaboration. Steelhead products have been deployed in

organizations ranging from the world’s largest corporations

with offices around the globe to small companies with a

couple of sites that are just miles apart. To learn more,
