FlexE Timeslot Damage Notification and Path Adjustment

The patent implements a feedback mechanism where the receive-end FlexE device monitors data blocks for errors and sends timeslot damage notifications back to the transmit-end device. When errors are detected in data blocks received from a specific timeslot, the receive-end device generates a notification containing the timeslot identifier and sends it to the transmit-end device, which then stops using that damaged timeslot. This closed-loop feedback system resolves the contradiction by enabling reliable detection of timeslot damage without requiring complex detection mechanisms at the transmit-end.

The patent applies preliminary action by proactively identifying and eliminating damaged timeslots before they can cause extensive packet errors. Instead of waiting for packets to be corrupted and then discarding or correcting them, the system continuously monitors data block integrity at the receive-end and pre-emptively stops using damaged timeslots by sending notifications to the transmit-end. This prevents the need for packet discarding or error correction operations, thereby maintaining both data integrity and transmission efficiency.

The patent utilizes segmentation by dividing the transmission system into multiple independent timeslots, each handled by separate processing components. This allows the system to maintain high transmission capacity through parallel processing while isolating potential hardware failures to specific timeslots. When a processing component fails, only the corresponding timeslot is affected and can be individually identified and stopped via the feedback mechanism, while other timeslots continue to operate normally, thus maintaining overall system reliability alongside high capacity.
