Data frame error recovery for multi-node systems

A multi-node system for performing data frame error recovery, comprising:

• a plurality of communication nodes configured to receive data packets broadcasted from other communication nodes within the multi-node system, wherein a communication node of the plurality of communication nodes includes:
• a communication interface;
• a controller communicatively coupled to the communication interface, the controller configured to:
• receive a data packet from another communication node via the communication interface;
• test the data packet to determine whether the data packet includes one or more bit errors;
• compare the data packet with one or more data packets stored in a recovery buffer to identify a plurality of duplicate data packets, each of the plurality of duplicate data packets having different alternative bits, when the data packet includes one or more bit errors;
• identify a duplicate of the data packet from the plurality of duplicate data packets based on which of the plurality of duplicate data packets has the fewest number of mismatched bits;
• identify one or more bits affected by the one or more bit errors based on a comparison between the data packet and the duplicate of the data packet;
• determine different combinations of bit values for the one or more bits;
• test the data packet with the different combinations of bit values for the one or more bits to identify a correct combination of bit values for the one or more bits;
• and
• recover the data packet based on the correct combination of bit values for the one or more bits.

A method of performing data frame error recovery, comprising:

• receiving a data packet at a communication node within a multi-node system;
• testing the data packet to determine whether the data packet includes one or more bit errors;
• comparing the data packet with one or more data packets stored in a recovery buffer to identify a plurality of duplicate data packets, each of the plurality of duplicate data packets having different alternative bits, when the data packet includes one or more bit errors;
• identifying a duplicate of the data packet from the plurality of duplicate data packets based on which of the plurality of duplicate data packets has the fewest number of mismatched bits;
• identifying one or more bits affected by the one or more bit errors based on a comparison between the data packet and the duplicate of the data packet;
• determining different combinations of bit values for the one or more bits;
• testing the data packet with the different combinations of bit values for the one or more bits to identify a correct combination of bit values for the one or more bits;
• and
• recovering the data packet based on the correct combination of bit values for the one or more bits.
