摘要： A method is provided for managing congestion of traffic in a packet switch, which comprises the steps of: providing more than two different congestion levels at the switch for handling traffic associated with at least two different priorities, one being a low priority traffic and another being a high priority traffic; for each traffic flow having a specific destination and priority, determining a current congestion level that matches a congestion control level which is selected from among the more than two congestion control levels, and associating a different set of operations for handling each respective traffic flow, depending on its priority and its current congestion level, and for each traffic flow, performing operations that match the respective associated set of operations, and wherein a rate at which these operations are performed for each respective traffic flow increases when a higher congestion level occurs at that respective traffic flow.

摘要： A method for utilizing a Spanning Tree Protocol (STP) in an Ethernet network wherein a number of VLANs are defined and a plurality of Ethernet switching nodes (A, B, C D E, F, G H) are interconnected via their ports (A1, . . . ,H4) so that each of the ports is initially assigned to one or more VLANs, and each of the VLANs is intended to enable traffic between two or more edge ports (D3, B3). The method comprises also-called pruning procedure initiated upon establishing a new STP topology (30) related to one or more VLANs. This procedure concerns a broadcast domain of at least one of the VLANs and is aimed at obtaining a sub-tree for each pruned VLAN in the new STP topology. The sub-tree is usually shrunk, bound by the edge ports assigned to the corresponding pruned VLAN, and thus eliminates broadcast traffic of the pruned VLAN to any Ethernet switch extending beyond the obtained sub-tree.

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： Configuration of a communication network can include obtaining a graph representing the communication network, generation of a the preplan assignment for the communication network, and configuration of the communication network according to the preplan assignment. The graph can be associated with shared risk link groups (SRLGs) and demands. Generation of the preplan assignment can include obtaining a headend assignment between each one of the demands and a headend vertex on the graph. Generation of the preplan assignment can further include obtaining a SRLG-distinguishing assignment between each headend and a corresponding reporting edge set. The reporting edge set for a headend can include sufficient edges to distinguish among SRLGs affecting the headend. Generation of the preplan assignment can further include obtaining a notification path assignment between each headend and each reporting edge in the corresponding reporting edge set for the headend.

摘要： The disclosed systems and methods support addition of bands to a multi-band optical interface. The systems and methods can include a multi-band interface device for optical networks. The device can include a multi-band optical amplifier, a C-Band Add/Drop multiplexer, an L-Band Add/Drop multiplexer and an amplifier noise source. The multi-band optical amplifier can be connected to the C-Band Add/Drop multiplexer and connected to the L-Band Add/Drop multiplexer through the amplifier noise source. The amplifier noise source be configured to generate a combination of bulk noise and an input transmission received from the L-Band Add/Drop multiplexer. The gain of the amplifier noise source can depend on the power of the received input transmission. The power of the received input transmission can be increased over a period of time, transitioning the amplifier noise source from acting as a bulk noise source to acting an amplifier.

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.
