摘要:
A method for restoring traffic in a network. The network includes plural distinct nodes interconnected by plural distinct spans, each span having working links and spare links. Each node has a digital cross-connect switch for making and breaking connections between adjacent spans forming span pairs at a node. Cross-connections between spare links in adjacent spans are made such that sets of successive nodes through which the adjacent spans form span paths form closed paths. A method of finding and construction closed paths is described in which statelets are broadcast through the network. In a preferred method of implementation of the method, the statelet broadcast occurs not in response to a network failure, but across the entire network before any particular span failure and may be carried out during normal network operations as a continual re-configuration of the network.

A method and apparatus for enabling a network-based solution for enterprise customers that is integrated with premise-based equipment is disclosed. The premise-based solution can be quickly enabled in the event that the primary network, e.g., VoIP network, connectivity is lost. The premise-based equipment, e.g. a VoIP switch, can be minimally configured and equipped to play the role of a hot standby proxy for network based VoIP services if connection to the primary VoIP network is lost. Intelligent services typically accessed in network based VoIP services can be enabled on the premise equipment and VoIP gateways to an alternate network, e.g., a WAN or a PSTN, can be activated. Network operators can remotely activate this equipment on behalf of the enterprise customer until the primary network connection is restored.

A system, method and computer program product are provided for policy-based billing for a network session. Initially, a plurality of packets is received by a plurality of analyzers. Thereafter, the packets are aggregated. Next, the plurality of packets is analyzed to identify a plurality of flows and an session associated with the flows. At least one application associated with the session is also identified. The session is then reconstructed utilizing the identified application. A user associated with the session is then identified along with a policy. The user is then billed for the session in accordance with the policy.

There is provided a system and method of disaster restoration of service of damaged or destroyed telecommunication network elements. A controller component is configured to select a damaged or destroyed network element after a disaster event. An engine component is configured to establish connectivity to an alternative network element and to transmit the service continuity data associated with the damaged or destroyed network element from a computer readable storage. The engine component is configured to execute one or more computer commands to the alternative network element so as to operate it with the service continuity data of damaged or destroyed network element. A restoration service package is transmitted to a replacement network element and instructed to use that service package to re-acquire the original network element's identity and provisioning information in order to restore the traffic that originally existed on the damaged or destroyed network element.

Technology for rerouting a data stream in a communication circuit switched mesh network comprising one or more cross-connecting nodes, the data stream comprises a plurality of data frames each associated with at least one overhead byte, and the rerouting is performed by using a path identifier while switching the data stream at one or more cross-connecting nodes; the path identifier is carried by at least one overhead byte associated with at least one of the data frames.

One embodiment of the disclosures made herein is a method for facilitating protection switching via failure prediction techniques. In accordance with such a method, an operation for monitoring a failure prediction parameter of at least one of the plurality of protected system elements is performed. During monitoring, an operation is performed for correlating a present state of the failure prediction parameter to a failure prediction criterion for determining whether one of the protected system elements has been met a failure prediction condition, thus identifying a failure predicted one of a plurality of protected system elements when the failure prediction condition is met. An operation is performed for determining whether a protection switching priority among a collection of failure predicted system elements applies to the failure predicted one of the protected system elements. In response to protection switching priority applying to the failure predicted one of the protected system elements or the failure predicted one being the only failure predicted system element, an operation is performed for downloading service information of the failure predicted one of the protected system elements to the protection system element. An operation is next performed for confirming failure of the failure predicted one of the protected system elements. Then, an operation is performed for switching communication service supported by the failure predicted one of the protected system elements for being supported by to the protection system element.

A traffic control method for intelligent network services is disclosed. When an overload state is detected, a service control point (SCP) requests a call gapping operation by transmitting a call gapping message containing a gapping information to a service switching point (SSP), the SSP executing the call gapping operation for controlling an intelligent network call to arrive only at the SCP that has requested the call gapping message by distinguishing between different physical nodes of each SCP.
摘要:
Restoration of an inoperative network element (12) such as a digital cross-connect system is accomplished by receiving updates from each element as they occur in a local controller network (18). The local controller network forwards the updates to a DCS-Operations support system (22) that generates a restoration map for each element in its native language, and thereafter updates each map upon receipt of each update. In response to a user command, the DCS-operation system directs (transmits) the update map either to directly the inoperative element or to an intermediate element to achieve restoration.
摘要:
A system and method for providing early warning notifications to telephone subscribers having calling number delivery service. The system uses an advanced intelligent network to initiate several calls in rapid succession to all calling number delivery subscribers located within a pre-determined geographic area. A code identifying the disaster warning message is transmitted to the subscribers' calling number delivery systems in place of an actual calling line identification. Subscribers having calling name delivery service receive the disaster code and a text message briefly describing the disaster warning.
摘要:
A Network restoration device for restoring static paths in a transmission network upon occurrence of a failure, the restoration device comprising means for retrieving an initial configuration of said transmission network from a central network managing device, means for tracking the current network status by tapping messages on a communication path between said network managing device and network elements, duplicating said messages, and evaluating them, means for detecting a failure to be restored by evaluating alarm messages, means for taking over control over the network from said network managing device upon detection of a failure, means for evaluating a restoration configuration of said transmission network and for restoring failed paths by deploying said restoration configuration, and means for informing said network managing device of the restoration configuration.
