摘要： A procedure for transferring wavelengths, and a system that operates in accordance with the procedure. The system comprises at least one network terminal, each including a switch and a controller. A plurality of wavelength sets are applied to the switch. The controller is arranged to operate the switch such that the switch (a) selects at least one wavelength from at least one of the plurality of wavelength sets, based on electrical monitoring at a port module external to the network terminal, and (b) outputs the at least one wavelength to an output of the at least one network terminal.

摘要： Multiple physical NEs may be presented to a network carrier as a single logical NE comprising multiple physical NEs. Alarms between the multiple physical NEs may be treated as internal connection alarms of the single logical NE instead of endpoint alarms of the multiple physical NEs. A number of alarms in the network may be reduced as well as alarm processing of the alarms at an Operational Support System (OSS), effectuating scaling of alarms as well as relaxing resource requirements (e.g., compute power, memory, etc.) of the OSS.

摘要： An optical ring network has one or more working wavelengths and multiple protection wavelengths adapted to support the working wavelength(s). Routing tables may be used in network nodes to assign traffic of a failed working wavelength to a protection wavelength. The protection technique may be applied to networks employing, for example, Dense Wave Division Multiplexing (DWDM).

摘要： A network element includes first and second multiplexers, first and second interfaces, and first and second selecting units. The multiplexers are communicatively coupled. The first interface is communicatively coupled to the first multiplexer and configured to receive multiplexed signals. The second interface is communicatively coupled to the second multiplexer and configured to receive multiplexed signals. The first selecting unit is communicatively coupled to the first and second multiplexers and configured to select between a signal received from the first multiplexer and a signal received from the second multiplexer. The second selecting unit is also communicatively coupled to the first and second multiplexers and configured to select between a signal received from the first multiplexer and a signal received from the second multiplexer.

摘要： A network element includes a processor that is configured to receive a request for performing an administratively-requested reroute (ARR) on a network. The ARR includes at least a first data plane operation on the network element and a second data plane operation on another network element. The network element is also configured to determine whether it is capable of performing the first data plane operation without interrupting network traffic on that network element. The network element is further configured to determine whether the other network element is capable of performing the second data plane operation without interrupting network traffic on that network element.
