DUPLEX MISMATCH DETECTION

摘要

Embodiments of the present invention provide techniques for both ends of a link suffering from duplex mismatch to correct the duplex mismatch. According to some embodiments, the half-duplex end of the link can detect that the other end of the link is in full-duplex mode by detecting late and/or very late collisions, and can correct the duplex mismatch by changing to full-duplex mode. According to some embodiments, the full-duplex end of the link can detect that the other end of the link is in half-duplex mode by one or more techniques including detecting cyclic redundancy check (CRC) errors and frame fragments, and can correct the duplex mismatch by changing to half-duplex mode.
