    • A method for optical network signaling processing of a signal from a first node to an end node through intermediate nodes is presented. The method comprises determining, in a first pass from the first node to the end node, available wavelengths and wavelength conversion at each node, the end node optimizing wavelengths using the available wavelengths and wavelength conversions, at each node, dropping a cross-connect command, in a second pass from the end node to the first node, choosing wavelengths for connection based on the optimizing step, in a third pass from the first node to the end node, receiving at each node a signal message and releasing unused cross-connect commands, the end node identifying the chosen wavelengths and releasing the unused resources, and transmitting the signal on the chosen wavelengths. Restoration paths can also be determined. Optimizing can include selecting and marking one or more backup wavelengths.
    • 提出了一种通过中间节点对从第一节点到终端节点的信号进行光网络信令处理的方法。 该方法包括在从第一节点到终端节点的第一遍中确定在每个节点处的可用波长和波长转换,所述端节点在每个节点处使用可用波长和波长转换优化波长,丢弃交叉连接命令 在从端节点到第一节点的第二遍中,在从第一节点到终端节点的第三遍中,基于优化步骤选择用于连接的波长,在每个节点处接收信号消息并释放未使用的交叉连接 命令,结束节点识别所选择的波长并释放未使用的资源,以及在所选择的波长上传输信号。 还可以确定恢复路径。 优化可以包括选择和标记一个或多个备用波长。
