Abstract

An apparatus and method for analyzing a network flow. The apparatus includes a parser for extracting flow identification information from the network flow, a flow metering unit, and a programmable controller. The parser and flow metering unit are controlled in parallel by the programmable controller, the programmable controller is implemented as state machine, and the state machine includes a transition rule memory, a rule selector, and a state register. The rule selector is configured for receiving an external input signal and an internal input signal from the state register. The rule selector is also configured for observing the internal and external input signal via the transition rule memory.
