NETWORK FAULT ISOLATION

摘要

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 centr al controller is operatively connected to the diagnostic units, the controller being adapted to communicate with and coordinate operations of the diagnosti c 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 f or improving fault isolation and fault reduction are also provided.
