Method and apparatus for routing traffic using asymmetrical optical connections |
| 摘要 |
A method, computer-readable storage device and apparatus for routing traffic in a reconfigurable optical add-drop multiplexer layer of a dense wavelength division multiplexing network are disclosed. For example, the method determines the reconfigurable optical add-drop multiplexer layer has asymmetric traffic, and routes the asymmetric traffic in the reconfigurable optical add-drop multiplexer layer over a plurality of asymmetrical optical connections, wherein the plurality of asymmetrical optical connections is provided with only uni-directional equipment in the reconfigurable optical add-drop multiplexer layer. |

1. A method for routing traffic in a reconfigurable optical add-drop multiplexer layer of a dense wavelength division multiplexing network, the method comprising:
determining, by a processor, the reconfigurable optical add-drop multiplexer layer has asymmetric traffic; and routing, by the processor, the asymmetric traffic in the reconfigurable optical add-drop multiplexer layer over a plurality of asymmetrical optical connections, wherein the plurality of asymmetrical optical connections is provided with only uni-directional equipment in the reconfigurable optical add-drop multiplexer layer, wherein the asymmetric traffic is determined by a symmetry ratio of an entire network being below a threshold. |
