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 network comprises nodes which support a plurality of different wavelength channels and support at least a first bitrate traffic type and the second bitrate traffic type on respective wavelength channels. A connection of the second bitrate traffic type is established on an available wavelength, if the wavelength offers an acceptable quality of transmission using a first quality of transmission calculation. Alternatively, a connection of the second bitrate traffic type is established on a wavelength which is spaced, by a guard band, from wavelengths used for connections of the first bitrate traffic type, if the wavelength offers an acceptable quality of transmission using a second quality of transmission calculation. The second quality of transmission calculation is less stringent than the first quality of transmission calculation, and can ignore the effects of interference due to cross-phase modulation. The guard band is a wavelength spacing at which the interference between a connection of the first bitrate traffic type and a connection of the second bitrate traffic type is less than a predetermined amount.

摘要： Slots (311) for transmission of data of a particular transmission type over an optical network are allocated by selecting a first available slot (313_2) at an ordinal position corresponding to a multiple of n and allocating the selected first available slot and the next n-1 consecutive slots (313_4, 313_5) from the selected first available slot (313_3), if all n-1 consecutive slots (313_4, 313_5) are available, for transmission of data of the particular transmission type. The data is transmitted over an optical network comprising a plurality of nodes (305, 327) interconnected by optical sections (301, 309, 329, 331) the nodes (305, 327) supporting a plurality of transmission types, wherein transmission of data of the particular transmission type requires a predetermined number n of consecutive slots. Alternatively the slots may be divided in groups (333, 335, 337) and slots are allocated to a group in which all slots are available.

摘要： In an optical communications network using bandwidth variable wavelength switching, routing and spectrum assignment for a traffic request for x sub-carriers of a super-channel, involves checking for an existing super-channel having sufficient potential sub-carriers not currently active. If not found, then possible paths for a new super-channel are identified and a path is selected and sub-carriers assigned. By trying first to use inactive potential sub-carriers of an existing super-channel, fewer super channels overall are needed, and thus fewer super transponders are needed. This can reduce blocking probabilities and can reduce capital costs. The search for possible paths can try to avoid or reduce overlap with spectrum of existing super channels, or compare possible paths by weighting according to amounts of overlap.

摘要： In a multi-domain network each domain, or Autonomous System (AS), has a route calculation entity (PCE A) which is responsible for computing paths between domains on behalf of clients. The route calculation entity (PCE A) sends advertisement messages to a route calculation entity (PCE B) in another domain. The advertisement message carries at least one of: inter-domain resource information and aggregated intra- domain information, such as simplified topology information or cumulative traffic engineering (TE) metrics. The inter-domain resource information can be inter-domain route or reachability information which is normally discarded by a routing protocol such as the Border Gateway Protocol (BGP) and can include inter-domain Traffic Engineering (TE) information such as reservable bandwidth.

摘要： A method of changing the spectral position of a lightpath between a source node and a destination node of an optical network. The optical network uses a flexible grid for spectral allocation and the lightpath has been allocated first spectral resources at a first spectral position. The method comprises, at the source node, reserving additional spectral resources for the lightpath which are contiguous in frequency with the first spectral resources. The method comprises re-tuning a light source at the source node such that the lightpath moves in frequency from using the first spectral resources at the first spectral position to using second spectral resources at a second spectral position, wherein the second spectral resources comprise at least some of the additional spectral resources. The method comprises releasing at least some of the first spectral resources. The source node continues to send traffic over the lightpath during the re-tuning.

摘要： An optical carrier selector system is provided for selecting a wanted carrier signal (f w ) from a multi-carrier signal comprising a plurality of carrier signals (f 1 -f N ). The optical carrier selector system comprises a series of optical filter devices (OFD 1 - OFD N-1 ). Each optical filter device of the series comprises an input port (201) for receiving a signal comprising two or more carrier signals, each optical filter device being configured to filter out an unwanted carrier signal. Each optical filter device also comprises an output port (203) for outputting at least the wanted carrier signal and any remaining signals that have not been filtered out by that particular optical filter device, and a drop port (205) for outputting the unwanted carrier signal (f uw ) that is being filtered out by the respective optical filter device. By outputting from a drop port the unwanted carrier signal that is being filtered out by the respective optical filter device, this has the advantage of enabling the operation of the optical carrier selector system to be monitored for proper operation, and controlled or adjusted if necessary.
