摘要： There is provided a method for optimizing the configuration of an optical network which is adapted to transport optical traffic along a path from a source node to a destination node, wherein the path can be routed via any one or more of a plurality of intermediate nodes in the optical network. The method comprises the steps of receiving an operating parameter of an optical device monitored in a plurality of nodes. The received operating parameter is compared with a threshold value. An operating status of a node is determined based on the comparison of the received operating parameter with the threshold value. The determined operating status of a node is used as a routing criteria for computing a path for routing traffic through the optical network.

摘要： Dynamic restoration involves routing and bandwidth assignment of an unplanned restoration path in a wavelength switched optical network (20), having regeneration nodes (60), nodes each having a ROADM (62) having drop paths and add paths. An electrical switch (68) provides configurable regeneration capacity by coupling selected drop paths to selected add paths. Some of the configurable regeneration capacity is kept for unplanned restoration paths. A PCE determines (120) routing and bandwidth assignments for an unplanned restoration path for the traffic flow to avoid a fault, and sends (130) configuration messages to the nodes to set up the unplanned restoration path dynamically and to configure the electrical switch to provide regeneration on the path. Keeping some reconfigurable regeneration capacity enables much longer unplanned paths to be found to avoid faults, and enables wavelength conversion if needed. Thus the reliability of finding at least one path avoiding the fault can be increased.

摘要： Routing and bandwidth assignment of new paths of different bandwidths, occupying different numbers of adjacent frequency slots in a wavelength switched optical network, involves selecting a route, and assigning a set of adjacent frequency slots. The assignment can place wider bandwidth ones of the new paths at an opposite end of a spectrum of the available frequency slots, to an end where narrower bandwidth ones are placed. A size of sets of available adjacent slots remaining after the assignment is likely to be increased, compared to a conventional first fit assignment. A wider subsequent new path can sometimes be accommodated along all or some of the route and thus the blocking probability can be lowered. The selecting of which of the possible routes to use can be made dependent on which has more sets of available adjacent frequency slots, or which has a wider gap between occupied slots.

摘要： An optical transmission device (10) includes a transmission unit (21), a filter unit (23), a detection unit (24), and a control unit (25). The transmission unit superimposes identical superimposition signals of a frequency modulation method on a plurality of optical signals that have identical destinations and that have adjacent wavelengths, and transmits resultant signals as one communication signal. The filter unit filters part of two optical signals having adjacent wavelengths from among the plurality of optical signals included in the communication signal. The detection unit generates an electric signal of a detection level representing an optical intensity of the two optical signals that were filtered by the filter unit. The control unit controls timings of superimposing the superimposition signals on the two optical signals respectively by controlling the transmission unit so that variation in the detection level becomes smaller.

摘要： The disclosure provides a method for implementing an optical label, including that: an optical network is domain-partitioned according to Reconfigurable Optical Add-Drop Multiplexer (ROADM) nodes, and one or more frequencies of label signal are allocated for each domain; in each domain, an allocated frequency of label signal is circulated among ROADM nodes and/or among carriers within an ROADM node according to a preset time-division rule; a label signal is sent on a carrier or an optical channel using a circulated frequency of label signal. The disclosure further provides a system for implementing optical label. With the solution of the disclosure, label-signal transmission may be implemented on more carriers or optical channels with less frequencies of label signal, thereby not only reducing demand of the system for the number of label frequencies, but also facilitate label-signal extraction.

摘要： A payload time slot of a first optical signal and a simultaneously transmitted payload time slot of a second optical signal have synchronous beginnings at a transmission side. A guard-band time slot of the first optical data packet signal and a simultaneously transmitted guard-band time slot of the second optical data packet signal have synchronous endings at the transmission side. A chromatic dispersion difference affecting the signal s is compensated, by setting the time duration of the payload time slot of the second optical data packet signal and furthermore also the time duration of the successive guard-band time slot of the second optical data packet signal at the transmission side, such that the successive guard band timeslot of the first optical data packet signal and the successive guard band time slot of the second optical data packet signal have at least a pre-defined overlap at a receiving side.
