A method and system for managing performance of over a multimedia content distribution network (MCDN), such as a digital subscriber line network, involves receiving an indication of an impairment in network performance from an MCDN client. The MCDN node associated with the client may be identified and a community of MCDN clients coupled to the MCDN node may be further identified. Impairment information, representative of MCDN equipment, may be collected for each of the MCDN clients. Detailed network diagnostics and field service may be performed for MCDN clients based on a characterization of the impairment parameters. After remediation of the MCDN node, collection of the impairment information may be terminated.

A method and system for monitoring a multimedia content distribution network (MCDN) includes receiving an indication that a network impairment has been detected at an MCDN node. MCDN clients associated with the MCDN node may be analyzed to detect an impairment signature, representing correlated impairments among the MCDN clients. Subsequent incoming service requests for the MCDN node may be bundled into a master service ticket. Users of the MCDN clients may be notified of the detected network impairment and of a status of ongoing remediation efforts.

Method and system to detect a predictive network signature

A method and system for managing performance of a multimedia content distribution network (MCDN), such as a digital subscriber line network, involves monitoring maximum data transfer rates and current data transfer rates for one or more MCDN clients. A ratio of the current data transfer rate to the maximum data transfer rate may be evaluated with respect to a threshold. When the ratio is less than the threshold, an associated MCDN node may be designated as a degraded node and subject to enhanced surveillance by an MCDN operator.

Method and system to proactively identify degraded network performance

A method and system for managing performance over a multimedia content distribution network (MCDN), such as a digital subscriber line network, involves accessing a record of historical values of a network service parameter for a plurality of MCDN clients. The historical values may be analyzed to detect network impairment associated with an MCDN node. Network diagnostics may be initiated for MCDN clients associated with the MCDN node. The result of the network diagnostics may result in localizing a source of the network impairment.
