PROBLEM TO BE SOLVED: To make it possible to appropriately communicate by unifying communication paths of both ways.SOLUTION: At each edge switch, the number of reception times of first-arrival packets that have arrived earliest is counted for each port, and after a certain time passes, if the switch is a main edge switch determined on the basis of a transmission source MAC address and a transmission destination MAC address, a port is determined on the basis of the number of reception times, and the determined port and the transmission source MAC address are registered to a table. On the other hand, if it is an auxiliary edge switch, after the certain time passes, the number of reception times is cleared once, and the number of reception times is counted. When the time passes again after that, a port is determined on the basis of the number of reception times in the same manner as the main edge switch, and the determined port and the transmission source MAC address are registered to the table. |
