Abstract
An apparatus that facilitates network security for input network traffic includes microcode controlled state machines, each of which includes a computation kernel. Rules applied to a network traffic segment are distributed across the computation kernels. At least two of the computation kernels include condition logic configured by microcode stored in an associated control store to evaluate a unique configured rule in microcode to produce modification instructions. A distribution circuit routes the network traffic segment to each of the microcode controlled state machines. A circuit generates a modification command by combining the modification instructions from each of the at least two computation kernels, and performs a modification of the input network traffic based on the modification command to produce modified output network traffic that facilitates network security.
