A method and apparatus for managing the quality of a communication link is provided. A performance of a communication line (i.e. digital subscriber line), being affected by code violations, typically impulse noise, is estimated. An application characteristic for the communication line is then imputed from Layer 2 and Layer 3 network levels attributes, such as upstream/downstream percentages, IP port usage, ATM cell count. A correlation is made between the performance and the application, and a decision model then applies a maintenance profile the communication line based on the performance and the application. The present invention provides a method and apparatus for managing a quality of service experienced by a user when running an application over a communication link. A performance for the communication link is estimated and an application characteristic for the communication link is imputed from data gathered regarding the communication link performance. A decision model is then applied to select an appropriate maintenance profile for managing the quality of service provided by the communication link. The selected profile is then applied to the communication link based on the performance and the application. Management of the quality of service includes selecting an appropriate profile to provide an acceptable user experience for the application and noise level.
