摘要： A method and system are provided for tracking the rerouting of logical circuit data in a data network. A disclosed example method involves updating reroute information in response to a dropped packet associated with a quality of service parameter having been exceeded. Transmitted data is rerouted to at least one logical failover circuit in the data network from at least one failed logical circuit associated with the exceeded quality of service parameter. The at least one logical failover circuit is selected based on a bit rate capability specified to be one of a committed bit rate, a variable bit rate, or an unspecified bit rate.

摘要： A disclosed example method involves determining a first quality of service parameter associated with a failed logical circuit, and a second quality of service parameter associated with a logical failover circuit. When the first quality of service parameter is equal to or less than the second quality of service parameter, data from the failed logical circuit is rerouted to the logical failover circuit without requiring authorization from a customer to communicate the data at the second quality of service parameter. When the second quality of service parameter is a lower level of quality than the first quality of service parameter, the customer is prompted for authorization to communicate the data via the logical failover circuit at the second quality of service parameter. When authorization is received, the data is rerouted to the logical failover circuit. When authorization is denied, the data is not rerouted to the logical failover circuit.

摘要： Methods and systems are provided for real time simultaneous monitoring of logical circuits. In accordance with an example method, first status information is requested for a first logical connection at a host end of a logical circuit comprising the first logical connection. The logical circuit connects a host device to a remote device and traverses a first local access and transport area, an inter-exchange carrier, and a second local access and transport area. The first local access and transport area is at the host end of the logical circuit, and the second local access and transport area is at a remote end of the logical circuit. A logical identifier of the logical circuit is identified based on the first status information. A second logical connection at the remote end of the logical circuit is identified based on the logical identifier of the logical circuit. Second status information for the second logical connection is requested after identifying the second logical connection. An indication of whether the logical circuit has failed is displayed based on the first and second status information.

摘要： A method and system are provided for automatically rerouting logical circuit data in a virtual private network (“VPN”). A dedicated logical circuit in the VPN is monitored for status information pertinent to the dedicated logical circuit. The dedicated logical circuit includes a primary communication path for communicating data. Based on the status information, a failure is identified in the dedicated logical circuit. Once the failure in the dedicated logical circuit is determined, a logical failover circuit is then identified. The logical failover circuit includes an alternate communication path for communicating the data for the failed dedicated logical circuit. After the logical failover circuit has been identified, the data from the dedicated failed logical circuit is rerouted to the logical failover circuit without manual intervention. After the data has been rerouted the logical failover circuit, a determination may be made as to whether the failure in the dedicated logical circuit has been corrected. If it is determined that the failure in the dedicated logical circuit has been corrected, then the data from the logical failover circuit is rerouted back to the dedicated logical circuit in the VPN without manual intervention.

摘要： A method and system are provided for on demand selective rerouting of logical circuit data. Upon a failed logical circuit being identified in the data network, one or more alternative logical failover circuits for rerouting data from the identified failed logical circuit is displayed in a menu on a display device. A selection of a logical failover circuit is made using a graphical user interface (GUI). Once the selection of the logical failover circuit is received, the data from the failed logical circuit is rerouted to the selected logical failover circuit. Upon receiving the selection of the logical failover circuit, a determination may be made as to whether a utilization percentage indicate of congestion in the selected logical failover circuit exceeds a predetermined threshold. If the utilization rate exceeds the threshold, then an alert is generated and the selection of an alternative logical failover circuit from the menu is requested.

摘要： For automatically identifying a failure in a logical circuit in a data network without manual intervention, the logical circuit includes one or more logical connections for communicating data in the data network. A network management module periodically requests trap data indicating the status of the logical connections in the logical circuit. After the trap data has been received by the network management module, the trap data is analyzed to determine whether any of the logical connections has failed. If it is determined that a logical connection has failed, the network management module may wait a predetermined time period to determine whether the failed logical connection has been restored. If after the predetermined time period the logical connection has not been restored, then the logical circuit is identified as having failed.

摘要： Methods and systems are provided for automatically renaming logical circuit identifiers for rerouted logical circuits in a data network. A first logical circuit identifier for a first logical circuit in a first network is identified. When a failure is detected in the first logical circuit, a second logical circuit identifier for a second logical circuit in a failover network separate from the first network is identified and the first logical circuit is renamed without manual intervention to identify the first logical circuit using the second logical circuit identifier. The second logical circuit is to reroute data from the first logical circuit.

摘要： A method and system are provided for automatically rerouting logical circuit data from a physical circuit failure in a data network. When a failure in a logical circuit is detected, a label or services name associated with the logical circuit is automatically associated with a logical circuit identifier utilized for identifying the logical circuit in the 10 data network. Once the logical circuit is associated with the logical circuit identifier, the logical circuit data may be automatically rerouted to a “failover network,” thereby minimizing lost data until the failure in the logical circuit is resolved. The logical failover circuit may be an already existing logical circuit provisioned over a dedicated backup physical circuit in the data network.
