摘要： A network management system can be configured to identify routes for satisfying a set of demands on an optical communication network using layer graph(s). The layer graph edges can have edge scores that indicate a cost of the edge. The network management system can generate the layer graph(s) using a network graph that represents the optical communication network and an associated sets of available frequency slots. The network management system can iteratively identify candidate path(s) on the layer graph(s) that correspond to each of the demands and determine a cost for each candidate path using the edge scores. In each iteration, the network management system can select the lowest cost candidate path, update the layer graph(s) based on this selection, and update the candidate paths for the remaining demands as needed. The network management system can similarly generate restoration paths for each of the demands.

摘要： Systems and methods are disclosed for configuring a communications network. In disclosed embodiments, a set of permissible service link decompositions and a set of basic service links may be obtained for the communications network. A spanning subset of service links for the communications may be generated. Generation of the spanning subset may include selecting a decomposition of a first service link from a set of permissible service link decompositions; updating the set of permissible service link decompositions based on the selected decomposition; and updating the set of basic service links using the updated set of permissible service link decompositions. In some embodiments, obtaining the set of permissible service link decompositions can include generating a set of permissible service link decompositions by traversing decomposition graphs generated for each of the service links. In some embodiments, the communications network can be configured to satisfy network demands using the spanning subset.

摘要： Techniques for migrating a plurality of communications services in a data communication network are disclosed. Aspects include accessing a migration map for the plurality of communications services in the data communication network; identifying a communications dependency between a first service and a second service in the plurality of communications services, wherein according to the migration map the first service is configured to migrate from a first route to a second route, the second service is configured to migrate from a third route to a fourth route, and the third route overlaps with the second route; determining, based on the identified communications dependency, a migration sequence for migrating the plurality of communications services in the data communication network; and migrating the plurality of communications services from a first plurality of configurations to a second plurality of configurations according to the migration sequence.

摘要： Dynamic fabric systems and methods are disclosed for providing connections between endpoints of a communication network. An exemplary dynamic fabric system can include backplane lanes, a dynamic fabric device, and a control device. The dynamic fabric device can include local fabric lanes and a network interface device configurable to communicatively connect the local fabric lanes to a network. The dynamic fabric device can also include a local switch configurable forward messages to backplane lanes and an interconnect configurable to statically connect local fabric lanes and corresponding backplane lanes. The dynamic fabric device can also include a controller configurable to create or break these static connections. The control device can provide instructions to the dynamic fabric device to create or break the static connections based on changes in the number of active dynamic fabric devices installed in the dynamic fabric system.

摘要： Systems and methods are disclosed for configuring a communications network. In disclosed embodiments, for a communication network comprising fiber optic cables connected by switches and transceiver-transponders, a graph representing the communication network can be obtained with edges representing the fiber optic cables, and nodes representing the switches and transceiver-transponders. A set of service links can be determined for a path in the communication network based on a set of demands for the path. Each service link can represent data transmission by one of the transceiver-transponders through one or more of the fiber optic cables connected by zero or more of the switches. Sets of service links can be iteratively selected for progressively longer initial segments of the path. When the initial segment comprises the path, the set of service links for the initial segment can be selected as the set of service links for the path.

摘要： Techniques for satisfying a plurality of service demands in a data communication network are disclosed. Aspects include identifying a first plurality of edges, each of which connects two of a plurality of nodes in the data communication network, wherein each of the first plurality of edges is associated with one of a plurality of unprotected service demands; generating a spanning tree comprising a second plurality of edges selected from the first plurality of edges, wherein the spanning tree connects all of the plurality of nodes that are connected by the first plurality of edges; and creating a set of service links based on the generated spanning tree.
