摘要： A system and method for imputing data into a database includes an imputing system operable to impute data based on outside plant construction principles. The imputing system includes an inventory database, a data engine, a search engine, and a loop engine. The inventory database includes a plurality of distribution records each associated with one or more cable pairs. The data engine determines if a desired distribution record corresponding to a desired cable pair includes missing data. The search engine searches a known class of serving terminals for complete distribution records and iteratively searches a sized binder group within the inventory database for one or more complete distribution records where the size of the binder group searched increases with each iterative search. The loop engine determines an imputed value for the desired distribution record based on the searching and imputes the value into the desired distribution record.

摘要： A method includes accessing network information stored at a remote device, the network information identifying one or more available physical locations to deploy one or more network nodes of a proposed network. The method further includes receiving data indicating a number of core layer nodes to be included in the proposed network. The method further includes determining a number of aggregator layer nodes to be included in the proposed network, the number of aggregator layer nodes determined based on incrementing a threshold number of aggregator layer nodes that supports a coverage area of the proposed network. The method further includes generating a network design of the proposed network. The network design identifies particular physical locations of the one or more available physical locations to deploy each of the core layer nodes and each of the aggregator layer nodes of the proposed network.

摘要： A method for automatically designing a switched metro Ethernet data is provided. During execution of the method, data network information, customer demand information, equipment information, and at least one design constraint is received. Based thereon, a potential topology design for the switched metro Ethernet data network is automatically established. The potential topology for the switched metro Ethernet data network can be a tree topology that is rooted at a predetermined hub node and that has a plurality of leaves. Each leaf is located at a customer location. In a particular embodiment, an aggregation node is placed at the hub node. Further, an aggregation node is placed at a predetermined redundant hub node. Additionally, an aggregation node is placed at another location in the tree topology.

摘要： One embodiment of the present invention provides a system that guarantees a stated failure-recovery time in an optical wavelength-division multiplexing (WDM) network. The system operates by first receiving a request at an ingress node of the WDM network to establish a connection from a source to a destination through the WDM network, wherein the request includes the stated failure-recovery time. The system then calculates a chain of restorable cycles within the WDM network between the ingress node for the source and an egress node for the destination, wherein each cycle in the chain of restorable cycles can guarantee the stated failure-recovery time. Finally, the system selects a section of each restorable cycle to be a primary path between the source and the destination through the restorable cycle.
