Duplex mismatch: Why duplex conflicts plague the network, part 1
Duplex mismatch problems -- caused by two ends of the Ethernet attempting a full-duplex connection, resulting in packet loss -- simply will not go away. After a decade of plaguing IP networks, duplex conflicts still seem to be the single worst source of performance degradation. Trivial to fix but ridiculously hard to identify and localize, mismatches recur frequently, as interfaces go up and down over time and network hosts are updated and changed. In column, Dr. Loki Jorgensen explores why duplex mismatches are difficult to conquer using auto-negotiation. Continue Reading
