摘要： A system for establishing a restoral route to bypass a failed component in a communications network. The network has components that include nodes and links. Each link connected to a node is either an input or an output link for that node. When a component failure is detected on a output link of a node, the system selects a source node and a target node for the restoral route and sends messages through output links of the source node to establish a restoral route to the target node. When a message to establish a restoral route to the target node is received at a node, the node forwards the message through its output links. When a message that a restoral route has been established to the target node is received through an output link of a node, the node connects the input link through which the message to establish a restoral route was received to the output link, and forwards the message that a restoral route has been established through the input link. When a message that a restoral route has not been established to the target node is received through each output link of a node, the node forwards the message that a restoral route has not been established through the input link. Thus, the nodes of the network send messages to one another to effect the establishing of a restoral route in a distributed and dynamic manner.

摘要： A method and apparatus for analyzing a telecommunications network and isolating failures within the network first analyzes the network to identify all non-terminating paths between two digital cross-connect (DXC) nodes and terminating paths that extend from one DXC node but terminate before reaching another DXC node. All non-terminating paths are assigned "failure spans" or maximum spans that can be restored with a single restoration route. All terminating paths that correspond to end nodes of the non-terminating path are selected, where each terminating path has a path identifier preferably indicating the inter-node connections of the path. The path identifier is compared to each failure span to create a table of correlations. A similar process is performed for all terminating paths that do not correspond to non-terminating paths in the network. When a failure occurs, all paths are identified for each corresponding alarm and compared to the previously constructed table. A failure span is identified as including a failure if one or more paths are on the failure span and are in alarm, and all paths which are off the failure span are not in alarm. Furthermore, the ports on each path in alarm can be collected to determine whether the network suffers from a full or a partial outage.

摘要： A system for establishing a restoral route to bypass multiple failed components in a communications network. The network has components that include nodes and links. Each link connected to a node is either an input or an output link for that node. When a component failure is detected on a output link of a node, the system selects a source node and a target node for the restoral route and effects the sending of messages through an output links of the source node to establish a restoral route to the target node. When a message to establish a restoral route to the target node is received at a node, the node forwards the message through its output links. When a message that a restoral route has been established to the target node is received through an output link of a node, the node connects the input link through which the message to establish a restoral route was received to the output link and forwards the message that a restoral route has been established through the input link. When a message that a restoral route has not been established to the target node is received through each output link of a node, the node forwards the message that a restoral route has not been established through the input link. Thus, the nodes of the network send messages to one another to effect the establishing of a restoral route in a distributed and dynamic manner.

摘要： A system and method are provided to diversely respond to changes in network topology and segment availability that occur between the time a restoration pre-plan is developed and the time it is executed. Changes that have occurred during this time are detected when the pre-plan is implemented. Dynamic responses to these network changes are manifest as real-time adjustments to the pre-plan during its execution in the form of a segment substitution or a segment swap.

摘要： Balancing logic is automatically generated from conversion logic in a data conversion system. The balancing logic balances source data from a source system with the corresponding converted data in a target system. The balancing logic determines whether the conversion was properly performed so as to balance the two varieties of data. The balancing logic is automatically generated by a computer system or other electronic device in response to examining conversion logic that is encoded in a script or other representation.

摘要： A method and apparatus analyzes network topology data of a telecommunications network. Each physically diverse path in the network is assigned a unique path identifier. Trunks along each path, and ports at nodes through which the trunks are routed, are assigned the corresponding path identifier. If a trunk fails, the ports facing the point of failure issue alarms that include the corresponding path identifier for the trunk. A computer or other system compares the path identifiers of the alarming trunks with the path identifiers of restoral routes, such as other trunks extending between end nodes at opposite ends of the failure. Only those trunks having path identifiers differing from the path identifier of the alarming trunk are selected as possible restoral routes for the failure.

摘要： A restoration system for restoring a communications network following a failure of one or more communications network components. The restoration system identifies spare segments and spans of spare segments in the original network configuration, as well as interconnected sub-spans of the identified spans of spare segments. The restoration system assigns a cost to the identified spare spans and spare segments. The costs are based on the cost of connecting a spare span or a segment as part of a restoral route and the cost of fragmenting a spare span. The restoration system uses these assigned costs to select a low cost combination of spare segments and spare spans to use as the restoral route.

摘要： A network emulator capable of emulating an entire restoration network improves the process of testing a centralized system for monitoring, restoration, and control of the system. The network emulator has a segmented process architecture such that emulation of the aspects of the restoration network is realized with discrete process components, including an alarm generator, an alarm feeder and a communications emulator. The alarm generator reads in a user-defined network event, analyzes network topology data to determine the impact of the event, and generates an alarms file specifying the alarms generated by the emulated network in response to the event. The alarm feeder reads additional user input specifying the nature of the event, reads the alarms file and determines the sequencing and timing of each alarm. The alarm feeder then feeds the alarms, in specific order and time intervals, to the communications emulator. The communications emulator emulates the actual communications of a network with the centralized system being tested. The communications emulator receives the sequenced alarms from the alarm feeder, formats the sequenced alarms into data messages in accordance with the specific type of devices being emulated, and transmits the messages to the centralized system being tested using an appropriate communications protocol.

摘要： A system for identifying preferred source nodes and preferred target nodes for nodes of a trunk within a telecommunications network. Each node is connected to an output link of the trunk. A preferred source node for a node is a source node of a restoral route to bypass the output link. A preferred target node for a node is a target node for a restoral route when that node is the source node of the restoral route. The system comprises a read restoration node topology component, a build restoral route table component, a build preferred node table component, and a download component. The read restoration node topology component that reads information describing the topology of the telecommunications network. The build restoral route table component builds a table of restoral routes for a trunk of the telecommunications network. The restoral routes are identified from the information describing the topology of the network. The build preferred node table component builds a preferred source node list and a preferred target node list for each node on the trunk based on the restoral route table. The download component downloads the preferred source node lists and the preferred target node list to the nodes of the trunk.

摘要： A method and related system dynamically determines the location of a network outage in a telecommunications network. A plurality of alarm generating network equipments are located at spaced sites along the network. Alarms are generated upon the detection of problems with a signal passing through continuous signal trunks connected between the alarm generating network equipments. The alarm data from the alarm generating network equipments is connected at a single point. Network topology data is stored in a database, defining the relative locations of the alarm generating network equipments in the network and their respectively connected trunks. The alarmed equipment ports are correlated with respective connected alarmed trunks from data obtained in the database as well as collected alarm data. The alarmed trunks are analyzed for identifying the corresponding minimum number of alarm generating network equipments that exist between the alarmed trunks thereby defining effected inter-equipment trunks. The alarmed trunks passing through a particular inter-equipment trunk are analyzed. The analysis then establishes a minimum common span of all alarmed trunks that pass through the inter-equipment trunk, and along which the outage occurs.
