Abstract:
1. A method for processing frames in a Fibre Channel network comprising: (a) receiving a frame having a frame header with a plurality of fields at a receive segment of a port; (b) determining if a translation cache of the port is enabled and if enabled, simultaneously comparing the plurality of fields of the frame header with a plurality of entries for a plurality of control words used by the translation cache; wherein the plurality of control words include different fields for the simultaneous comparison with the plurality of fields of the frame header; (c) based on the simultaneous comparison in step (b) determining if there is a match between an entry of the received frame header and a control word entry; and (d) based on the match in step (c), removing data words in the received frame header, if de-encapsulation for the received frame is enabled; translating the received frame header using information generated by the translation cache, if translation for the received frame is enabled; encapsulating the frame with an encapsulation header, if encapsulation for the received frame is enabled; and routing the frame based on a translation cache setting if translation cache based routing for the frame is enabled.
