摘要： Embodiments of the invention relate to a method (400) for routing traffic through a network having a plurality of nodes, at least one of said plurality of nodes being an integrated node including first and second technologies integrated inside the same node platform, the method comprising: applying (402) a transformation algorithm to the plurality of nodes for determining at least one virtual link between at least two ports of the plurality of nodes; and performing (404) a routing algorithm using the at least one virtual link to determine an optimal virtual route for the traffic through the network based on at least one cost parameter associated with the at least one virtual link. By applying a transformation algorithm to a plurality of nodes in a network, virtual links can be created between virtual ports in the nodes, which are homogenous and allow all routes through the network to be considered concurrently during a routing algorithm. This allows an optimal route to be determined based on cost parameters associated with each virtual link.

摘要： Routing traffic across a network having an optical layer (40) and an electrical layer (30), involves using a common topology representing the optical and electrical layers of the network. The common topology is such that an individual port of a respective optical device in the optical layer (40) is represented as corresponding virtual nodes (145), coupled by virtual links (155), in the common topology together with a representation of nodes and links of the electrical layer. The routing path in terms of the common topology is mapped back into a routing path through the actual optical devices (50) of the optical layer. By moving the handling of colour (including wavelength assignment, wavelength continuity and colour selection where it is tunable/selectable) and direction constraints to the preliminary step of creating the common topology, the routing process can be simplified.

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 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.

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 (103) 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 (107) and a path is selected and sub-carriers assigned (140). 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 multi-domain network (10) comprises domains (AS A - AS E) of different network technology types. A network domain (AS A) comprises a plurality of network nodes (12, 14) connected by links (13) and comprising border nodes (12) which connect with other network domains (AS B, AS C, AS D). In a first domain (AS A) of a first technology type, a method comprises determining an intra-domain topology of the nodes (12, 14) and links (13) of the domain by collecting values of at least one network topology parameter of the first technology type. The method determines a summarised intra-domain topology of paths between border nodes (12) of the domain which is described using values of at least one summarised network topology parameter. Values of the summarised network topology parameter are derived from the values of the network topology parameter of the intra-domain topology of the first technology type. The summarised network topology parameter is part of a common set of network topology parameters for advertising between domains comprising apparatus of different technology types. A domain can comprise multiple layers of different technology type.
