Abstract:
1. A method for relaying information in frames among nodes of a packet switching network, the method comprising: acquiring incoming information frames by a data controller that is coupled to a processor and a memory, said incoming information frames including header portions designating format information, frame alteration commands specifying and instructing changes to information in the frames, and packets containing information data; converting the incoming information frames from one network protocol to a different network protocol by parsing the frame alteration control blocks to obtain said frame alteration commands and changing the information included in said frames as instructed by said frame alteration commands; relaying altered frames to a different node of the packet switching network; wherein the frame alteration commands are included in one or more frame alteration control blocks in the frame; and wherein the frame alteration control blocks include a type field specifying the type of frame, wherein the frame alteration commands are specific to the specified type of frame, and wherein a plurality of types of frame are specifiable in the type field, at least one of the plurality of types of frame being associated with a first network protocol and at least one different one of the types of frame being associated with a second network protocol different from the first network protocol.
