摘要： Techniques for providing closed-loop control and predictive analytics in packet-optical networks are described. For example, an integrated, centralized controller provides tightly-integrated, closed-loop control over switching and routing services and the underling optical transport system of a communication network. In one implementation, the controller includes an analytics engine that applies predictable analytics to real-time status information received from a monitoring subsystem distributed throughout the underlying optical transport system. Responsive to the status information, the analytics engine applies rules to adaptively and proactively identify current or predicted topology-changing events and, responsive to those events, maps reroutes packet flows through a routing/switching network and control and, based on any updated bandwidth requirements due to topology changes, dynamically adjusts allocation and utilization of the optical spectrum and wavelengths within the underlying optical transport system.

摘要： The embodiments disclosed herein provide fast recovery of a network signal path by, in the event of a failure or unacceptable degradation in a signal in the original network path, diverting the optical signal passing through the network to a preselected bypass optical path which is maintained in a warm or operational state. The optical elements on the bypass optical path are available network resources which may, during part or all of the time the bypass path is designated for a node in the primary optical path, be in use to transmit other optical signals in the network. By maintaining the resources in the designated bypass path in a warm or operating state, fast rerouting and recovery of an interrupted signal is possible.

摘要： A multi-failure resolution optical node includes an operating system wavelength path and two or more standby system wavelength paths which are assigned to the operating system wavelength path and have been assigned a ranking. It further includes a node control unit that can separately operate the operating system wavelength path and the standby system wavelength paths in a normal power consumption mode or a reduced power consumption mode. Thus, it is possible to provide an optical node with which power consumption is reduced and with which switching to a standby system wavelength path can be performed quickly in response to a failure in the operating system wavelength path.

摘要： A first set of signal carriers of a plurality of signal carriers may be determined to be faulty. The first set of signal carriers may be for transmitting a first set of respective lane signals of a plurality of lane signals. A second set of signal carriers of the plurality of signal carriers may be identified as not faulty. The second set of signal carriers may be for transmitting a second set of lane signals of the plurality of lane signals. Based on the determining and identifying, one or more of the first set of lane signals may be routed from the first set of signal carriers through a first subset of the second set of signal carriers, the routing of the one or more of the first set of lane signals may cause a bandwidth capacity to increase to a highest available bandwidth.
