种电中继在电网元时信令建立的方法及光网元、电网元

本发明实施例种电中继在电网元时信令建立的方法及光网元、电网元，所述方法通过将第五接口的属性映射到第三接口的属性，并通过路由洪泛将所述第三接口的属性通知所述光网元所在光网络的所有光网元，使得所述光网元根据信令建立所述光网元本地波长连接，同时所述光网元下发消息，使得所述电网元根据所述消息建立所述电网元的本地波长连接，从而实现当电中继在电网元时，建立经过电中继的波长交换路径。 Embodiments of the present invention provide a signaling establishment method when an electrical regenerator is on an electrical network element, an optical network element, and an electrical network element. According to the method, a property of a fifth interface is mapped to a property of a third interface, and all optical network elements on an optical network on which the optical network element is located is informed, by means of routing flooding, of the property of the third interface, so that the optical network element establishes a local wavelength connection for the optical network element according to signaling; and the optical network element delivers a message, so that the electrical network element establishes a local wavelength connection for the electrical network element according to the message, thereby imp
