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： A path computation element for a communications network, receives link advertisements from hybrid nodes (10) of the network and selects paths for new traffic flows based on the received link advertisements. The hybrid node has switching matrices (20, 30) operable using different protocols, and has internal links between the switching matrices. The link advertisements indicate a maximum and a minimum bandwidth on any one of the internal links for a new traffic flow. The element can select a path via the hybrid node for a new traffic flow according to the bandwidth of the requested new traffic flow and according to the maximum and the minimum bandwidth indicated by the link advertisements. Advertising the maximum and minimum bandwidths available for a single new traffic flow for the internal links can enable more efficient path computation with little additional cost and hence maintain scalability of the link advertisements for larger networks.

摘要： A method of changing the spectral position of a lightpath (11) between a source node (B) and a destination node (D) of an optical network. The optical network (2) uses a flexible grid for spectral allocation and the lightpath has been allocated first spectral resources (50) at a first spectral position. The method comprises, at the source node (B), reserving (101) additional spectral resources (51) for the lightpath which are contiguous in frequency with the first spectral resources (50). The method comprises re-tuning (105) a light source (33) at the source node (B) such that the lightpath moves in frequency from using the first spectral resources (50) at the first spectral position to using second spectral resources (54) at a second spectral position, wherein the second spectral resources comprise at least some of the additional spectral resources (51). The method comprises releasing (106) at least some of the first spectral resources (50). The source node continues to send traffic over the lightpath during the re-tuning (105).

摘要： A node 800 of a multi-layer communication is capable of routing a message signal via one or more different layers (for example a PSC layer, TDM layer, LSC layer) in the multi-layer communication network. The node 800 comprises a first interface 801 for receiving a path message 803 containing routing information for routing an associated message signal through the multi-layer communication network. One or more second interfaces 805i to 805N are provided for transmitting a message signal to one or more respective layers in the multi-layer communication network. A processing unit 807 is adapted to determine if the path message 803 contains protection information 40 indicating that protection switching is to be performed in one or more different layers of the multi-layer communication network, and if so, establish a protection switching mechanism in the one or more different layers using the protection information 40 provided in the path message 803.

摘要： Path computation involves determining (120, 930) an aggregate cost for a portion of the path, based at least on the power consumption attributable to use of interfaces along that portion, comparing (130, 930) the portion of the first possible path with a different portion corresponding to a different possible path for the traffic request, based at least on their respective aggregate costs, and selecting (140, 930) which portion to use for the traffic request based on the comparison. Having path selection influenced by the power consumption values, can lead to lower overall consumption in operation than relying only on optimizing nodes individually without regard to how the nodes are used. Path selection can take into account indications of which parts are in a power down mode, and can involve powering up such parts if needed.

摘要： A node for an optical network has an electrical selector (30, 35) coupled to a first transponder for selecting which of first or second connections, is carried. A connection controller (80, 130) cooperates with other nodes to set up the first connection on a main path using a second transponder, and to reserve a first restoration path for the first connection. A second connection (best effort traffic) is set up on at least part of the reserved first restoration path by controlling the electrical selector. If the main path fails, the first connection is restored by controlling the electrical selector to select the first connection for the first restoration path in place of the second connection. By having an electrical selector, a change can be made more rapidly than if done only optically.
