Packet processor with programmable application logic
摘要
<p>A data communication switch includes a backplane and multiple packet switching controllers. At least one packet switching controller includes programmable application logic for generating application data for a packet. The application logic is contained in key builder and lookup table of an application engine. The key builder contains one or more schema programs for generating keys and key controls using classification information and header data of inbound packets. The schema programs can be loaded onto the key builder during fabrication of the packet switching controller or in field. The keys and key controls are used to lookup the application data from the lookup table. <IMAGE></p>
