PRODUCT SUMMARY
The
NITROX
Soho
CN22x Secure Communication Processors integrate Cavium Networks’ widely deployed security
technology with a MIPS32 CPU and several system peripherals. This combination results in a market leading product
with high throughput multi-tunnel IPSec and SSL performance for Soho/SME VPN and IPsec Gateway solutions.
Additionally, Cavium Networks complements this highly integrated solution with IPSec and SSL software solutions for
fastest time to market for new products. The heart of
NITROX
Soho
CN22x SCP are the MIPS32 CPU and the micro-
programmed GigaCipher core, which allow for future upgrades and flexibility in supporting all cryptographic operations
and protocol layer functions.
Figure 3: Adaptive Security Processing
Packet Processing in Mbps
Figure 3 shows how the CN22x core provides adaptive processing
power that can be used for all cryptographic operations and
protocol processing. This feature is unique to
NITROX
family
and allows for flexible response to dynamic load. Dynamic
Adaptive processing is enabled by the GigaCipher’s ability to
accelerate both the asymmetric algorithms used for tunnel
establishment and the symmetric ciphers + hashing algorithms
used in bulk data encryption. This adaptive nature of
NITROX
Soho
allows vendors to build balanced systems that can
handle dynamic traffic conditions.
