Abstract
An embodiment of an apparatus that facilitates network security and traffic monitoring for input network traffic includes a plurality of microcode controlled state machines, each of which includes a computation kernel. A plurality of rules applied to a network traffic segment are distributed across the computation kernels. Each of the computation kernels includes condition logic configured by microcode stored in an associated control store to evaluate a unique configured rule in the microcode to produce an associated output. A distribution circuit routes the network traffic segment to each of the plurality of microcode controlled state machines. An aggregation circuit generates a decision on which forwarding of the network traffic segment is based, where the decision is a logical combination of the associated output of each of the computation kernels.
