摘要： A method for rapidly restoring disrupted communications services between nodes of a network following a loss of service due to a circuit outage such as may occur, for example, as a result of an optical fiber cable break. The method is operable, however, irrespective of the transmission technology. Treating the telecommunications traffic as a commodity, a multicommodity model is developed using a measure of the commodities desired to be restored between network nodes and the capacity available for restoral in spare and impacted edges of the network. Action variables are established by use of representational "dummy nodes pairs" interconnected by "action edges." A multicommodity algorithm is applied to the model and to the decision variables to determine reroutes and actions to be taken within nodes of the network to effect the restoral reroutes. Preferably, the process is carried out in real time or near real time by computing apparatus and such that the outage is located via a control network and whereby the instructions for restoral actions are returned to the network nodes. Operation also preferably takes into consideration the priority of the telecommunications commodity to be restored and the relative costs of restoral so that higher priority commodities are restored first at lowest cost.

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： Difficulties with prior disrupted communications restoration systems are overcome by employing for each node of a communications network a restoration processor in which predetermined functions of the restoration process are managed by respective ones of a plurality of manager modules. The manager modules are arranged to be directly interconnected only with a so-called restoration manager that coordinates the operations of the modules and provides for their interconnection needs. In a preferred embodiment, four manager modules, a) a user interface manager module, b) a digital cross-connect system (DCS) manager module, c) a distributed communications manager module and d) a core algorithm manager module, are interconnected and coordinated by the restoration manager. Additional robustness to the restoration process is provided by way of enhancements to the functionality of the core algorithm manager module. These enhancements include: a) improved glare processing (resolution of contention for a particular resource), b) "broadcast" of takedown messages, c) elimination of the need for time-outs during automatic restoration, d) a "peek ahead" routine that immediately takes down a needed resource that is already on a list to be taken down, e) use of a "minimax factor" and f) a "quick fix" technique for use in cases of limited failure of circuits between two nodes. The restoration process can also be cascaded so that it sequentially restores one level at a time, the levels being defined by the hierarchy of digital transmission rates employed in the network.

摘要： A public telecommunications system includes a local exchange 10, an element manger 11 for managing the exchange 10 and a configuration manager 12 for managing the element manager 11. The element manager 11 is located with the exchange 10 and the configuration manger 12 is situated at a distant location. The exchange 10, element manager 11 and configuration manager 12 are connected by communication links 18, 19. In order to provide a new or existing customer with basic telephony services or one or more supplementary services such as call forwarding, the configuration manager 12 sends an appropriate set of requests to the element manager 11. If one or more of the requests are not successfully performed in the element manager 11, the configuration manger 12 sends further requests to the element manager 11 to cancel the requests which have been successfully performed and thereby return the element manager 11 to its original configuration.

摘要： A network management system prepares an optimum configuration table corresponding to a failure of a transit trunk and distributes the same to each TDM, and thereby the optimization of reconfiguration of a high-speed digital network is enabled.User data are transmitted and received in accordance with route information table defined beforehand in each TDM. On the other hand, network management information is sent to all trunks other than a receiving trunk for the managing information when flooding is designated by the network management system. Accordingly, the management information can be sent without fail if any route to the TDM to be supplied with the management information exists. When source-routing is designated, the communications of the managing information can be implemented efficiently, since the route is set by the management information.Moreover, each packet exchanger provides route identifiers defined individually for correspondence to local trunks, and transit route information set in each packet is recorded by using the route identifiers of each packet exchanger. Route information determined in the flooding process is then used in subsequent source-routed communications.

摘要： A method for restoration from a fault in a communication network formed by interconnecting a plurality of nodes including at least one set of node equipment each including a line terminal equipment and an optical cross-connect equipment, via a plurality of transmission lines using optical fibers. According to this method for restoration from a fault, if a line terminal equipment of at least one set of node equipment has detected a fault in an optical fiber under communication, it gives a command functioning as trigger for optical fiber change-over to an optical cross-connect equipment included in the node equipment. Upon receiving this command functioning as the trigger, the optical cross-connect equipment exchanges change-over control information indicating optical switch setting situation between it and an optical cross-connect equipment included in another node equipment, and forms a restoration route.

摘要： A telecommunications network architecture is known comprising a switching system for effecting basic call processing to set up, maintain and clear calls, and service-providing means (SPA) communicating with said switching system for providing services additional to said basic call processing. Due to the high availability requirements typically placed on telecommunications networks, the service providing means will generally need to be of a fault-tolerant design. A fault tolerant architecture is provided that relies on the checkpointing to a reliable store of state data for services currently being provided from first service logic of the service-providing means; should the first service logic fail, a second service logic is brought into operation and provided with required state data on current services from the backup store. To reduce the amount of checkpointing of data by the first logic, state data is only checkpointed when the corresponding call has reached a stable phase, the loss of a call during setup being much more acceptable than after it is been established.

摘要： In a first node of an optical network, an OAM (operations, administration and maintenance) controller produces an electrical OAM signal to control an optical cross-connect switch. This OAM signal is converted to an optical OAM signal and optically multiplexed with an optical payload signal associated with an optical path established in the cross-connect switch, producing an optical multiplex signal which is transmitted. A second node of the network demultiplexes the transmitted signal into an optical payload signal and an optical OAM signal, the latter being converted to an electrical OAM signal and used by an OAM controller of the second node for updating the OAM information. The updated OAM information is used to control the optical cross-connect switch of the second node. The demultiplexed optical payload signal is associated with an optical path established in the cross-connect switch of the second node.

摘要： A method and system for augmenting a communications network with spare components to efficiently re-route network traffic following a failure of one or more network components. The provisioning system of the present invention identifies components that are not configured into the communications network, but that could be configured into the communications network. The provisioning system identifies restoral routes to bypass a failed network component assuming that each of the identified components were configured into the network. The restoral routes are identified based on cost assigned to the identified components and the component currently configured into the network. The provisioning system then selects those identified components that are frequently used in the restoral routes to be configured into the communications network.
