TCAM AND FPGA-BASED PACKET PROCESSING METHOD AND DEVICE

摘要

A TCAM and FPGA-based packet processing method and device. The method comprises: according to a packet type of a received packet, extracting, by a switch, data header information about the packet, wherein the data header information comprises at least one piece of unary information and at least one piece of multiple information; searching for flow tables corresponding to all pieces of information in each data header in parallel and integrating output results; and judging whether a multiple flow table corresponding to the multiple information is idle when the data header information is multiple information, and sending the multiple flow table to a processing queue of the multiple flow table when the multiple flow table is not idle. By means of the solution provided in the embodiments of the present invention, the deep parsing conducted on a packet can be effectively realized, and the results obtained by looking up a table previously can be effectively associated in a manner of combining parallel connection with series connection and the processing efficiency of the packet can be effectively increased.
