    摘要： A method is provided for protection switching in an optical network. The method may include communicating a switch request for initiation of protection switching in response to a determination that at least a minimum frequency of interrupts indicating failure of an optical signal has occurred over a first period. The method may also include communicating a switch request for cessation of protection switching in response to a determination that no more than a maximum frequency of interrupts indicating failure of an optical signal has occurred over a second period.

    摘要： Systems and methods for triggering fault information insertion in an optical network are disclosed. In accordance with certain embodiments of the present disclosure, a method may include detecting, by a network element, occurrence of an event. The network element may also determine whether the event comprises a triggering fault condition in which fault information is to be communicated. The network element may additionally insert fault information into a data packet. The network element may further communicate the data packet to at least one neighboring network element.

    摘要： Systems and methods for identifying a fault location in an optical network are disclosed. In accordance with one embodiment of the present disclosure, a method for identifying a fault location in an optical network comprises monitoring, by a network element, an eastward optical path and a westward optical path for faults. The method further comprises transmitting, by the network element, a first data packet along the eastward path and a second data packet along the westward path. The first and second data packets comprise an eastward fault indicator and a westward fault indicator comprising information associated with any eastward or westward faults occurring on the eastward or westward paths. The fault indicators indicate the existence of an eastward or westward fault and the network element that detected the fault.

    摘要： In accordance with embodiments of the present disclosure, a method for identifying a target signal in an optical transport network frame structure may be provided. The method may include determining an Access Identifier (AID) for the target signal. The method may also include determining at least one attribute for the target signal. The at least one attribute may define at least one of an Optical Transport Network (OTN) multiplexing structure associated with the target signal and one or more attributes associated with one or a higher order or an intermediate higher order optical data unit entity for a supporting entity of a lower order optical data unit associated with the target signal. The method may further include identifying the target signal based on the AID and the at least one attribute.

    摘要： Determining an active/standby state of one or more modules of a network element includes provisioning a path through the modules, where the path is for providing a service. A signal is introduced into the path, and the path is monitored. The service is established to be ready in accordance with the monitoring. The modules are determined to be in an active state in response to establishing that the service is ready.
