TRANSMISSION DEVICE AND SYNCHRONIZATION CONTROL METHOD

摘要

A transmission device includes: a detector to detect a head pattern indicating a head of data for each of ports that receives the data; a write controller to write the data to a memory provided for each of the ports, based on a detection timing of the head pattern detected by the detector; a determination unit to determine, among ports for each of which the head pattern has been detected by the detector, a specific port for which a total delay amount is minimum, the total delay amount being a total sum of delay amounts from the head pattern related to the specific port to each of the head patterns related to ports other than the specific port; and a read controller to read the data from the memory, based on the detection timing of the head pattern related to the specific port determined by the determination unit.

1. A transmission device comprising:
a detector configured to detect a head pattern indicating a head of data for each of ports that receives the data; a write controller configured to write the data to a memory provided for each of the ports, based on a detection timing of the head pattern detected by the detector; a determination unit configured to determine, among ports for each of which the head pattern has been detected by the detector, a specific port for which a total delay amount is minimum, the total delay amount being a total sum of delay amounts from the head pattern related to the specific port to each of the head patterns related to ports other than the specific port; and a read controller configured to read the data from the memory, based on the detection timing of the head pattern related to the specific port determined by the determination unit.
