The SW5000 Network Content Processor (NCP) is a high-performance processor
optimized for Layer 4 protocol termination and Layer 5 to 7 content processing.
The SW5000 performs hardware-based functions that accelerate packet and content
processing. The SW5000 enables OEMs to build flexible and scalable network
systems that run advanced line rate IP applications. It enables OEMs to develop
best-in-class single-application or multi-application products, such as a security
gateway with combined firewall, VPN, and intrusion detection features.
The SW5000 combines the performance of hardware with the flexibility of software.
Processing-intensive functions are embedded in specialized silicon to maximize
performance. Protocol state machine implementation and error handling reside
under firmware control. This combined approach gives the SW5000 unparalleled
scalability and flexibility. With 5 Gbps (full duplex) throughput, the SW5000
facilitates a wide range of system designs and performance options. The architecture
provides a layered approach that takes advantage of industry-standard processors,
coprocessors, and memory.
Unlike network processors, which examine data "packet-by-packet",
the SW5000 performs stream-based content processing. By converting packet-based
traffic into contiguous streams of data and processing the resulting streams,
the SW5000 maximizes content processing efficiency.
