Abstract
A method and associated apparatus for automating the filtration and generation of information in a packetized communication system. A filtration table includes entries used in recognizing a valid packet received at a node in a communication system. A mask field in each entry is applied to appropriate fields in the packet (e.g. the ordered set as applied to Fibre Channel communication systems) to determine the validity of the packet with regard to the receiving node. Rules in a field of each entry further qualify the recognition of a received packet (e.g. ordered set) by testing the reception of the packet against other logical rules. Action fields in each record permit definition of actions to be invoked automatically (e.g. automatic adjustment of fill transmissions in Fibre Channel applications) in response to receipt and recognition of a particular packet. The set of packets recognized by the receiving node may be modified by adding, deleting, or modifying the entries in the filtration table. The programmable filtration thereby permits simple modifications to the protocol supported by the receiving node. Programmable generation capabilities of the present invention permit rapid i…
