Abstract: 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.

Abstract: 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.

Abstract: 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.
