    摘要： The present invention provides a system, apparatus and method for modularly adapting a network node architecture to function in one of a plurality of potential node types. The architecture includes a configurable switching element, integrated optics, and a plurality of modules that allow a “type” of node to be adapted and configured within the base architecture. The module interfaces may be optical or electrical and be used to construct various different types of nodes including regenerators, add/drop nodes, terminal nodes, and multi-way nodes using the same base architecture.

    摘要： The present invention provides a system, apparatus and method for accurately identifying optical or digital impairments on a span using FEC errors identified at an intermediary node. This information may be provided to an end node within a network to switch to a redundant path around the impaired optical path or span therein. In one embodiment of the invention, signal degradation is identified by analyzing FEC data within a FEC decoded signal at an intermediary node. An identification of signal degradation provides an indication of a potential failing span within an optical link, which may be provided in-band or out-of-band to a terminal node so that a signal may be switched around a failing path, or span therein, prior to an actual failure event.

    摘要： A network device is configured to store parameters identifying a respective quality of service (QoS) to apply to corresponding different types of data flows; initiate establishment of a network channel between a source device and a destination device through an optical network; receive first and second data flows destined for the destination device, where the first data flow and the second data flow may have first and second data flow types; identify a first QoS and a different second QoS to apply to the first and second data flows based on the first and second data flow types and based on the parameters; apply the first QoS to the first data flow and the second QoS to the second data flow to form processed first and second data flows; and transmit, via the network channel, the processed first and second data flows towards the destination device.
