Optical communication path opening method and management control apparatus

Abstract

Provided is a method for opening an optical communication path, in which one or more optical switches include a plurality of first ports and a plurality of second ports, and a management control device switches connection such that other first ports grouped with a transmission port connected first port of the one or more optical switches connected to a transmission port of the one subscriber device are sequentially connected to one second port to which a response request signal is input, transmits the response request signal to the one second port each time the connection is switched, specifies a reception port connected first port connected to a reception port of the one subscriber device in accordance with reception of a response signal in response to the response request signal, and sets a connection relation between the ports of the one or more optical switches such that an optical signal input to the transmission port connected first port reaches an optical transmission line to which a reception port of another subscriber device serving as a communication partner is connected and an optical signal transmitted from a transmission port of the another subscriber device reaches the reception port connected first port.
