| 20100014855 | Fault location system and method for OC-N facility degradation - A system and method is disclosed that detects the onset of failing optical subnetwork network elements and minimizes the volume of Performance Monitoring (PM) parameter data that must be acquired and trend across a provisioned path by monitoring digital (SONET/SDH) section PM parameter data first, which is used to trigger an examination to determine which optical subnetwork is experiencing degradation. Threshold Crossing Alerts (TCAs) are set for digital section PM parameter data and when a digital section PM parameter is greater than or equal to its TCA, the method identifies which subnetwork is degrading. Once a subnetwork is identified, analog PM parameter data is acquired for network elements employed in the identified subnetwork and determines from monitoring the network elements' analog PM parameter data the network element(s) that is degrading. A maintenance ticket is issued identifying the failing network element(s). | 01-21-2010 |

The system includes a utility server that is adapted for receiving the utility consumption telemetry data from the utility customer. The utility server is disposed at a network service provider that serves the customer with bundled network services. Utility consumption telemetry data is stored in a database and consumption reports for the customer may be generated for each of the plurality of utility companies serving the customer. | 05-13-2010 |
| 20100124170 | Methods and Apparatus to Detect Border Gateway Protocol Session Failures - Methods and apparatus to detect border gateway protocol (BGP) session failures are disclosed. A disclosed example apparatus comprises a database interface to obtain provisioned configuration information for a provider edge (PE) router, a BGP engine to receive one or more BGP messages from a route reflector, the one or more BGP messages representing a list of active routes for the PE router, and a session analyzer to compare the list of active routes with the provisioned configuration information to determine whether a provisioned route is not present in the list of active routes, and to declare a BGP session failure when the provisioned route is not present in the list of active routes. | 05-20-2010 |
| 20100161770 | USER-CONTROLLED NETWORK VIDEO MANAGEMENT - A process and system for user-controlled configuration of an Internet protocol network. The user may supply input for generating a network classification profile, which includes a number of classes of service (COSs) for prioritizing network traffic, including video transmission. A quality of service (QOS) may be measured and compared with a COS for video transmission. Depending on the measured QOS, a network alert may be issued and a priority of packets associated with the COS for video transmission may be increased. | 06-24-2010 |
