Described herein are a device and a method for performing a network analysis. In one aspect, the device includes a feature extraction circuit, an input processing circuit, and a reconfigurable neural network circuit. In one aspect, the feature extraction circuit receives a raw packet stream, and obtains temporal statistics of a flow, according to a first packet attribute or a first flow attribute of the raw packet stream. In one aspect, the feature extraction circuit generates a feature data including one or more statistical features based on the temporal statistics of the flow. In one aspect, the input processing circuit scales the feature data to generate an adjusted feature data. In one aspect, the reconfigurable neural network circuit performs computations corresponding to a neural network on the adjusted feature data to determine a predicted network characteristic.

Feature extraction for inline network analysis

Flexible switch logic packet processing includes receiving a first packet associated with a particular traffic flow, generating a switching decision behavior in a first cycle of the particular traffic flow by selecting one or more processing floors of a programmable pipeline based on a received profile signal indicating a type of processing required for the first packet, and performing packet processing on the first packet using the selected one or more processing floors of the programmable pipeline. In some aspects, an ingress packet processor is configured to generate a first switching decision behavior using the selected processing floors of a first programmable pipeline in the ingress packet processor. In other aspects, an egress packet processor is configured to perform a packet action on the passed first received packet based on a second switching decision behavior using the selected processing floors of a second programmable pipeline in the egress packet processor.
