Deterministic Networks Announces Spinout; Company to Enter Network Performance Optimization Market

Deterministic Networks Inc. today announced that it has
completed its spinout from Gilat Satellite Networks (Nasdaq:GILTF) and
has begun operating as an independent entity.
   Formerly a networking and security tools vendor, Deterministic
Networks was acquired by Gilat in July of 2000 to create products
which enhanced performance of data traffic in Satellite Networks. Over
the past five years, Deterministic has built the NetworkJustice(TM)
line of products including FairShare, a bandwidth management/traffic
shaping system, Bandwidth Bank, delivering volume-based network
controls, Traffic Analyzer, which does large scale analysis, and
Policy Agent, which provides end-to-end optimization, marking, and
quality of service (QoS). These products have been deployed worldwide
helping optimize performance and maximize numbers of users in Gilat's
customer networks.
   Deterministic President and CEO Steve Jackowski said, "We've
learned a lot about securely maximizing throughput and numbers of
users in complex satellite networks. With the proliferation of
wireless technologies, we believe we can extend these lessons to show
the same levels of performance improvements in terrestrial networks."
   Jackowski explained, "Satellite networks, with their inherent
delay, are just the most extreme examples of wireless networks. If we
can optimize performance there, justifying costs of satellite
transponders, we can optimize performance of any type of WAN --
wireless or wired."
   Gilat's Vice President, Research and Development Yossi Gal said,
"We believe Deterministic has a major opportunity outside the
satellite environment and we wanted to encourage Deterministic to
pursue this opportunity. These products, which have earned their
stripes in satellite environments, are planned at providing
substantial performance improvements in terrestrial networks as well."
   NetworkJustice products are software-based, running on a variety
of hardware platforms, from single-processor-embedded systems, PDAs,
and phones to fully redundant servers.
   NetworkJustice products are available now from Deterministic
Networks.
