* Force10 Networks uses NetBSD to build Software Scalability
   into FTOS Operating System

NEW YORK CITY, February 13, 2007: The NetBSD Foundation today
announced that Force10 Networks(R), the pioneer in building and
securing high performance networks, has leveraged NetBSD(R) as the
foundation for the Force10 Operating System (FTOS). Based on the open
source UNIX-like system, FTOS provides the software scalability and
resiliency that powers the Force10 TeraScale E-Series(R) family of
switch/routers.

"Our customers require a high level of scalability and resiliency to
build networks that can expand as new applications are added while
maintaining predictable performance," said Sachi Sambandan, vice
president of engineering at Force10 Networks. "The unique kernel
structure of NetBSD allows us to provide our customers with a
best-in-class software architecture that supports carrier class
resiliency and accelerates development of new features."

As a UNIX-like operating system, NetBSD provides unparalleled protocol
maturity and stability. Process modularization allows control plane
functions to be separated and given fair CPU scheduling while memory
protection minimizes corruption across process boundaries. Together,
these two features enable Force10 to provide its customers with a high
performance, fault tolerant system that isolates switching, routing
and management functionalities from each other in a multi-processor
control plane architecture. Additionally, NetBSD supports 17
microprocessor families, enabling a high degree of portability that
allows Force10 to easily port FTOS across multiple hardware
architectures.

"Industry leading networking companies recognize that system
scalability and resiliency are built upon a secure, solid yet portable
software foundation," said Alistair Crooks, president of the NetBSD
Foundation.  "We're delighted with Force 10's endorsement of NetBSD as
the basis of its high performance operating system, which will result
in benefits for both organizations."

The Force10 TeraScale E-Series provides leading resiliency and
scalability. Based on a system architecture that distributes
switching, routing and management functionalities between three
distinct processors, the TeraScale E-Series protects against unplanned
network downtime.  Additionally, fully redundant power supplies,
processor modules and switching fabrics guarantee maximum uptime.

  * About NetBSD

NetBSD is a general-purpose Open Source operating system that provides
interfaces for a wide range of applications on a big number of
different hardware platforms, all from one source tree. Applications
can range from proprietary closed source applications to Open Source
software that are made available easily through the NetBSD Packages
Collection, pkgsrc. The NetBSD operating system has a special focus on
providing its application platform on a large number of hardware
platforms, ranging from vintage hardware to modern desktop, server and
embedded hardware. Visit our webpage at www.NetBSD.org for more
