1. An optical switching apparatus of an E-UTRAN Node B (eNB), comprising:

  • a source input end and a destination output end, wherein the apparatus further comprises an optical switching module, wherein the optical switching module comprises a fiber transceiver module, a transmission address module, a switching control module and an optical switching and routing module, whereinthe fiber transceiver module is configured to receive an optical signal which carries transmission address information from the source input end and to transmit the optical signal;

    the transmission address module is configured to receive the optical signal transmitted by the fiber transceiver module, to query routing, and to manage and maintain transmission address(s);

    the switching control module, connected with the transmission address module, is configured to obtain the transmission address information of the optical signal, to analyze and select an optical switching mode, and to transmit a routing control signal which carries the transmission address information and the optical switching mode; and

    the optical switching and routing module is configured to receive the optical signal of the transmission address module and to transmit the same to the destination output end by the fiber transceiver module, to receive the routing control signal of the switching control module, to select routing according to the route control signal and to transmit the optical signal to the destination output end via the fiber transceiver module;

    wherein after the routing selection succeeds, the optical switching and routing module is configured to return the routing selection information after the success to the switching control module;

    wherein after receiving the routing selection information returned by the optical switching and routing module, the switching control module is configured to update a routing snapshot table thereof and transmit the routing selection information to the transmission address module;

    and the transmission address module is configured to update a transmission address routing learning table thereof according to the routing selection information.
