Abstract: Methods and systems are provided for management of frame alignment events in optical transport networks. The method includes receiving a plurality of frames by a network element and detecting a frame alignment event by the network element. The method further includes receiving a characteristic information (CI) signal by the network element, and disabling, based on the received CI signal, monitoring of a status field for a finite period.

Abstract: A network element is disclosed. In accordance with some embodiments of the present disclosure, a network element may comprise a network interface configured to communicatively couple to a network, and a controller communicatively coupled to the network interface. The controller may be configured to determine a delay-measurement interval, and to perform a plurality of delay measurements at a respective plurality of randomly determined times within the delay-measurement interval. Performing a delay measurement may comprise sending an outgoing signal, receiving an incoming signal, and determining a delay time based on the outgoing signal and the incoming signal.

Abstract: A method of network communications includes determining an access identifier (AID) for an egress signal through a network interface of a network element, an Optical Transport Network (OTN) multiplexing structure identifier (MSI) associated with the egress signal through the network interface, another AID associated with a defined ingress signal through the network interface, another OTN MSI associated with the defined ingress signal through the network interface, and associating the egress signal and the defined ingress signal based on the AIDs and OTN MSIs. The first OTN MSI is not equal to the second OTN MSI.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A composition having good gas barrier properties can be prepared from a metal silicate, clay and a polymer emulsion, provided that the proportions of these components are maintained such that the silicate comprises at least 70% by weight of the solids in the composition, and the clay and polymer each comprise at least 1% by weight of the total solids in the composition.

Abstract: Determining an active/standby state for an interface unit includes determining an entity active/standby state for each entity of one or more entities of the interface unit. If each entity active/standby state is standby, then an aggregated active/standby state of the interface unit is established to be standby.

Abstract: 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.
