The Internet, with its constantly improving data communications infrastructure, moves vast amounts of data every second. To process data at a low latency and high throughput, networking equipment vendors use dedicated hardware. At the 4 Gb/s to 40 Gb/s level, processing is done using expensive, purpose-built application-specific integrated circuits. From the 100 Mb/s to 4 Gb/s level, processing is usually performed using a combination of general-purpose CPUs, network processors, and field-programmable gate arrays (FPGAs). Processing throughput below 100 Mb/s is performed using either an x86 CPU or an embedded processor.
