About VIPRION

The VIPRION Application Delivery Controller`s (ADC) innovative chassis and blade
architecture extends the power of the F5 BIG-IP product family, and is an ideal
solution for enterprises and service providers seeking to scale their
application delivery infrastructure while keeping device configuration and
management simple. Unlike other ADC platforms, performance blades can be added
on-demand as network environments and applications require increased processing
power. As blades are added, management of the device remains simple, since all
blades operate together in a unified solution. And individual blades can be
installed or removed without network disruption, as VIPRION automatically
reroutes traffic to the other blades.

Due to VIPRION`s industry-leading ADC performance, the solution is ideal for
companies seeking to leverage next-generation networking capabilities such as
IPTV, VoIP, and other Web 2.0 technologies. Learn more by visiting
