Embodiment Construction

[0027]The present invention provides techniques for improved fault isolation and fault reduction. Under centralized control, diagnostic devices can be placed at various locations in the communication network. These diagnostic devices may communicate with user terminals to determine, for example, problems or symptoms that the user is experiencing when attempting to send or receive data, despite the user terminal's inability to communicate using an appropriate protocol for the desired network interaction. A problem or symptom is user-reported evidence of a failure in the network. A failure may also be referred to as a cause or root cause. With the help of centralized control (if required), the end device, through communication with users and other parts of the network, can isolate faults in the network, indicate and record the fault and remedial actions, and initiate remedial actions. Faults can be monitored and steps taken to reduce their frequency. The terminal device may b...

Abstract

Techniques are provided for improved fault isolation and fault reduction. A system for use with a data network includes multiple diagnostic units each adapted to communicate with the network including to a network user. A central controller is operatively connected to the diagnostic units, the controller being adapted to communicate with and coordinate operations of the diagnostic units, to instruct the diagnostic units to perform tests adapted to help isolate a network fault, and to analyze test results received from a diagnostic unit to attempt to determine the network fault. Various methods for improving fault isolation and fault reduction are also provided.

Description

technical field [0001] The present invention relates to networks such as communication and data networks, and in particular to isolating faults in such networks. Background technique [0002] Communication and data networks are rapidly growing in use and complexity. For example, the number of people using the Internet to send and receive data is increasing every day. Also, people are using the Internet more as more websites appear and because users can conveniently use more online services such as shopping than just accessing information. The increase in information and service resources, such as the ever-increasing number of web sites, has added to the complexity of the Internet. As the use and complexity of networks increases, so does the number of problems experienced by users. [0003] Network service providers hope to reduce the impact of network problems on users and the costs borne by network problems. In order to reduce the impact of problems such as downtime, in...
