Embodiment Construction

[0020] best practice

[0021] See the accompanying drawings that depict exemplary embodiments. figure 2 is an exemplary upper-level system diagram 200 . A processor is defined herein as a computer or computing device having a central processing unit (CPU) and addressable memory, wherein a computing device may be configured by executable machine-readable instructions, circuitry, or a combination thereof to Make it functional with a specific computing device. A network may consist of a source node containing a processor, a destination node containing a processor, and a network link deployed between these nodes. The source node can generate a message, such as a command for the destination node. This exemplary message can be prepared and sent by multiple network interface cards. exist figure 2 In the exemplary figure of , the source node 210 is connected to the network through two network interface devices 215, 220 or computer circuit boards which may be network interface car...

Abstract

A receiving network node (210) configured to select from received packets differing by time of initial transmission from a sending network node (230), and accepting for transmission, based on initial transmission time, the selected packets to an application layer (740). An internet-worked processor node configured to: (a) read a sequence number and an originator identifier of a received packet message (810); (b) compare a stored highest sequence number associated with the originator identifier with the received packet sequence number (820); (c) if the received packet sequence number is less than or equal to the stored highest sequence number associated with the originator identifier, then discard (840) the received packet; and (d) if the received packet sequence number is greater than the stored highest sequence number associated with the originator identifier, then deliver (860) the message of the received packet to an application based on an upper layer protocol.

Description

[0001] Inventors: Roland Mitchell Koch, Daniel Bailey Hirana Denny and W. S. Sechrist [0002] Cross References to Related Applications [0003] This application claims the benefit of U.S. Provisional Application Serial No. 61 / 245,170, filed September 23, 2009, and this application also claims the benefit of U.S. Provisional Application Serial No. 61 / 319,363, filed March 31, 2010, for all The disclosures of these applications are hereby incorporated by reference for purposes. technical field [0004] Embodiments relate to redundant message processing, and more particularly to message layer processing of redundant messages from the same source node and having different IP addresses. Background technique [0005] Figure 1 is a listing of the Open Systems Interconnection (OSI) model. The OSI model can be represented as a media layer with bit, frame and packet data units and as a host layer with data and data segments. These layers can be further subdivided into physical laye...
