摘要:
A process and system for user-controlled configuration of an Internet-protocol (IP) network wherein the user may supply input for generating a network classification profile (NCP), which includes a number of classes of service (COSs) for prioritizing network traffic. Network packets belonging to a COS may be classified according to a packet parameter. The NCP may be used to prioritize packets sent to the network from a network ingress router. A queuing profile for scheduling packets received from the network based on the NCP may also be generated and used by a network egress router. The packet parameter may be based on information in the packet header.

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.
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.
摘要:
A method of diagnosing a transmission loop in an Internet protocol television (IPTV) network includes configuring the loop as an open loop and performing a single-ended loop test (SELT), configuring the loop as a terminated-loop and performing another SELT, subtracting a trace of the first SELT from a trace of the second SELT, and determining the length of the loop from the result. A service assurance system in an IPTV network includes a test module and a DSLAM coupled to a residential gateway by a transmission loop. The test module operates to determine that a fault condition on the IPTV network is caused by a fault in the loop, direct the DSLAM to perform an open loop SELT and a terminated-loop SELT on the loop, receive the results of the SELTs, and determine a location of a tap on the loop based upon the results.

摘要:
A method can be used to address a condition experienced by a customer when using a network. The method can include receiving a first communication from the customer, wherein the first communication is related to the condition of a video content as experienced by the customer, reviewing a log for an alarm, and testing a portion of the network that would process the video content, wherein testing generates a test result. The method can also include correlating the condition to a service parameter, an alarm, a maintenance event, a test result, or any combination thereof. The method can further include sending a second communication to the customer related to the condition. In one embodiment, the method can be fully or partly automated using a system.

摘要:
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.
摘要:
A system that incorporates teachings of the present disclosure may include, for example, a server comprising a controller to monitor a physical layer, a data link layer and a network layer of an Internet Protocol Television (IPTV) network, obtain a plurality of alarm signals from one or more of the physical layer, the data link layer and the network layer that are associated with an undesired condition of the IPTV network, synthesize the plurality of alarm signals to determine a correlation, obtain topology information associated with network devices in the IPTV network, and isolate the undesired condition to a network component in the IPTV network using the correlation and the topology information. Other embodiments are disclosed.
