Abstract:
1. A method for transmitting data toward an endpoint node, the method comprising: receiving, at an intermediary node, a first data frame comprising a data packet; beginning to retransmit, by the intermediary node, the data packet contained in said first data frame toward said endpoint node in a second data frame prior to performing a first cyclic redundancy check (CRC) using a frame CRC field in said first data frame, said frame CRC field having been computed based on at least one non-CRC field of said first data frame; performing, by said intermediary node and subsequent to beginning said retransmitting, said first CRC on said first data frame using said frame CRC field; determining, as a result of said first CRC and by said intermediary node, that said first data frame is corrupted, containing one or more errors; and transmitting, by said intermediary node toward said endpoint node, a frame trailer associated with said second data frame which indicates that said data packet contained in said second data frame is corrupted, containing one or more errors.
