A network data classifier statistically classifies received data at wire-speed by examining, in part, the payloads of packets in which such data are disposed and without having a priori knowledge of the classification of the data. The network data classifier includes a feature extractor that extract features from the packets it receives. Such features include, for example, textual or binary patterns within the data or profiling of the network traffic. The network data classifier further includes a statistical classifier that classifies the received data into one or more pre-defined categories using the numerical values representing the features extracted by the feature extractor. The statistical classifier may generate a probability distribution function for each of a multitude of classes for the received data. The data so classified are subsequently be processed by a policy engine. Depending on the policies, different categories may be treated differently.

An equalizer for serial data communications can be configured to compensate for the effects of deterministic jitter. The equalizer can be configured to compensate a received serial data stream for the effects of data-dependent jitter as well as duty cycle distortion jitter. The equalizer can be configured to determine the value of one or more previously received symbols and compare them to a recovered symbol. The equalizer can adjust a variable delay positioned in the serial data path to introduce a delay into the data path that is based in part on the received data stream. The equalizer can be configured to vary the delay when any of the one or more previously received symbols is different from the recovered symbol, and can be configured to maintain a constant delay if the one or more previously received symbols is the same as the recovered symbol.
