MontaVista Linux Enables Carrier/Telco Industry to Leverage High Performance of Cavium OCTEON
Processors

Certified interoperability of MontaVista Linux Carrier Grade Edition delivered to designers of
multicore processor-powered devices

SANTA CLARA, Calif. ? July 31, 2008 ? MontaVista® Software, Inc., the leader in embedded Linux®
commercialization, today announced that MontaVista Linux Carrier Grade Edition (CGE) 5.0 now
supports Cavium Networks (NASDAQ: CAVM) OCTEON? CN58XX, CN56XX, CN52XX, CN50XX, and CN38XX
processor families, enabling embedded developers to use the widely adopted MIPS64-based OCTEON
architecture to create high performance multicore applications that are multi-threaded and
core-aware while delivering the interoperability, high availability, and field serviceability that
carriers need.

As the only Linux in the world that complies with three key industry standards (Carrier Grade Linux
4.0 registration, LSB 3.0 certification, and IPv6 logo certification), only MontaVista CGE is
proven to include essential carrier grade features and to interoperate with industry software and
hardware. MontaVista Linux brings commercial-grade quality, integration, hardware enablement,
expert support, and the resources of the MontaVista development community to developers using
Cavium OCTEON multicore processors.

?MontaVista customers using Cavium OCTEON multicore processors include many of the world? largest
manufacturers of network equipment,? said Dan Cauchy, senior director of market development,
carrier and mobile products for MontaVista Software. ?OCTEON processors incorporate advanced
multi-layer application acceleration for networking control, data and services applications. These
processors have low power consumption levels while delivering unprecedented performance to enable
real-time applications such as Layer 2-7 packet processing, which are supported by the real-time
capabilities of MontaVista Linux.?

?We have multiple network equipment provider (NEP) customers that ask for MontaVista Linux Carrier
Grade Edition due to its quality and reliability,? said Amer Haider, director, strategic marketing
and ecosystem development at Cavium. ?We have worked closely with MontaVista to make sure that
MontaVista Linux enables our customers?design teams to exploit the high performance of OCTEON
CN58XX, CN56XX, CN52XX, CN50XX, and CN38XX processors for control and data plane applications while
providing the high level of reliability required by telecom and wireless carriers.?

?We are pleased that MontaVista Linux CGE supports Emerson Network Power? OCTEON-based packet
processing products, including our ATCA-9305 blade and our AMC-9210 module,? said Jorge Magalhaes,
vice president, marketing for the Embedded Computing business of Emerson Network Power. ?By working
closely with MontaVista, we are able to provide leading-edge carrier grade blades and
highly-available platforms to network equipment providers, providing our customers the freedom to
focus their efforts on differentiating services and applications.?

"Carrier grade" is a term for software and hardware products that support public telecommunications
and data communications networks. Carrier grade products require extremely high degrees of
reliability, scalability, and performance to provide an uninterrupted flow of the enormous volume
of high-bandwidth data and voice needed for today's multimedia communications. MontaVista Linux
Carrier Grade Edition is the most widely deployed carrier grade Linux solution in the world, and is
used by seven of the top eight NEPs, including Alcatel-Lucent, Motorola, and NEC.

MontaVista Linux Carrier Grade Edition 5.0 for Cavium OCTEON CN58XX, CN56XX, CN52XX, CN50XX, and
CN38XX processors is available now from MontaVista directly and through its distributors.
