    • A method and a protection switching arrangement for protection switching of any one of a plurality of optical signals of a multi-wavelength optical signal from the failure of an optical component is provided. The multi-wavelength optical signal which contains the optical signals is itself rerouted by the use of wavelength agnostic rerouting elements, after which a tunable optical filter is used to obtain from the multi-wavelength optical signal the particular optical signal which would have been affected by the failure. In embodiments of the invention where the failed component is a switching fabric, the multi-wavelength optical signal is rerouted away from the failed switching fabric through a redundant switching fabric after which the particular optical signal is obtained with use of the tunable optical filter.
    • 提供一种用于保护多波长光信号的多个光信号中的任何一个与光学部件的故障的切换的方法和保护切换装置。 包含光信号的多波长光信号本身通过使用波长不可知重新路由元件而被重新路由,之后使​​用可调谐光学滤波器从多波长光信号获得将受到影响的特定光信号 失败。 在本发明的其中故障组件是交换结构的实施例中,多波长光信号通过冗余交换结构被重新路由远离故障交换结构,之后使用可调谐滤波器获得特定的光信号。

    • A network planning tool and method for configuring a connection-oriented packet network over a WDM optical network without an optical control layer, such as a SONET/SDH layer. The optical network includes a plurality of optical fibers interconnected through nodes and the connection-oriented packet network, such an Ethernet network, MPLS network, or pseudowire network, includes two or more terminal devices. The method and tool function by building an association between the components of the physical layer, such as the optical fiber, and their geographic location or path. The connection-oriented packet network is configured by building multi-link trunks (MLTs) between terminal devices, where the MLTs are built by aggregating lightpaths that traverse distinctive geographic paths. The MLTs are planned and configured through aggregating lightpaths that traverse incongruent sets of photonic elements. A predetermined target for resiliency to physical failure events may determine the degree of congruence allowed between the sets of photonic elements associated with lightpaths in the same MLT.
    • 一种网络规划工具和方法,用于在无光控制层(例如SONET / SDH层)的WDM光网络上配置面向连接的分组网络。 光网络包括通过节点互连的多个光纤和面向连接的分组网络,诸如以太网,MPLS网络或伪线网络,包括两个或多个终端设备。 该方法和工具功能通过在诸如光纤的物理层的组件之间建立关联,以及它们的地理位置或路径。 面向连接的分组网络通过在终端设备之间建立多链路中继(MLT)来配置,其中MLT通过聚合穿过不同地理路径的光路来构建。 MLT通过聚合穿过不一致的光子元素的光路来规划和配置。 对于物理故障事件的弹性的预定目标可以确定在相同MLT中与光路相关联的光子元件组之间允许的一致性程度。
