摘要:
A method and apparatus for addressing a congestion condition in a communication network are disclosed. For example, the method receives an alert for at least one of: a trunk or a Permanent Virtual Circuit (PVC), where the trunk or the PVC is associated with a route. The method determines whether the alert is associated with a congestion condition by determining whether a trunk utilization has exceeded a first predetermined threshold for the trunk or for the at least one trunk supporting the PVC. The method then rebuilds the route if the first predetermined threshold is exceeded for the trunk or for the at least one trunk supporting said PVC.

Systems and methods for managing problems that are determined to be chronic problems with network devices or circuits are disclosed. The systems and methods receive data indicating a problem with a network device or circuit and determine based on the data a first action to be performed on the network device or circuit. Upon determining that a recurring problem exists for the network device or circuit, a rule set is used to determine if the data indicates a chronic problem. Upon determining that a chronic problem exists for the network device or circuit, the rule set is used to determine a monitoring period for the network device or circuit. Further, within the monitoring period a performance indicator that indicates that the network equipment or circuit is performing acceptably or unacceptably is used to determine further actions for the network device or circuit.

A method can be used to detect a problem, isolate the cause of the problem to a particular device in which the cause resides, and potentially repairing the particular device. In one embodiment, the method can be fully automated using a system. In another embodiment, the method may be partly automated. In this particular embodiment, the system can perform most or all of the testing or diagnosis automatically. The system can perform the method until a point where human intervention is required. The problem, the cause, and particular device may be known at the time notification is sent to customer care, a workcenter, or another network operations center. With the information regarding the problem, cause and particular device, a technician or other personnel can be dispatched and repair the problem more quickly than if only the problem is provided and the technician needs to perform the testing and diagnosis.

A system that incorporates teachings of the present disclosure may include, for example, a server having a controller to receive information from a set top box that is associated with an undesired condition being experienced by a user of the set top box where the information is inputted into the set top box by the user, determine a failure condition associated with the information, perform a first diagnostic process to isolate the failure condition between a network failure and a customer premises equipment (CPE) failure, and transmit correction instructions to the set top box for presentation to the user when the failure condition is isolated to the CPE failure. Other embodiments are disclosed.

Methods and apparatus to detect and restore flapping circuits in IP aggregation network environments are disclosed herein. An example method for use in maintaining a communication network includes retrieving information related to an operating state of a device associated with a network disturbance; determining whether the information related to the operating state of the device is indicative of a flapping condition; when the operating state information indicates that the flapping condition is present in the network, determining a cause of the flapping condition; when the cause of the flapping condition is a physical cause, selecting a first recovery procedure; and when the cause of the flapping condition is a logical cause, selecting a second recovery procedure different from the first recovery procedure.

A method and an apparatus for detection and prevention of a slow response on a network are disclosed. For example, the method selects a router automatically for testing in response to a ticket indicating a slow response, and performs a diagnostic test on the router, wherein the diagnostic test comprises at least one of: a protocol diagnostic test, a circuit diagnostic test or, a congestion diagnostic test. The method then performs at least one remedial step to address a root cause that is identified by the diagnostic test, wherein the root cause is associated with the slow response.

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.

A method and apparatus for providing trouble isolation for a Permanent Virtual Circuit (PVC) on packet networks are disclosed. For example, the method receives an alert or a ticket for a Permanent Virtual Circuit (PVC) down or a PVC degraded and starts a correlation window for said PVC and port alert or ticket. The method then gathers a plurality of port and PVC alerts for a duration of said correlation window and determines whether or not a port down or a port degraded alert is received along with a PVC down or a PVC degraded alert in said correlation window for one or more ports associated with said PVC.
