An automatic network diagnostic method is also disclosed.
Claims16
An automatic fault diagnostic network system comprising an automatic diagnostic system and a connection unit for connecting a plurality of network elements to said automatic diagnostic system,
- wherein said automatic diagnostic system comprises a fault detection unit for detecting an individual fault,
- a test unit for running a test to find a cause of the individual fault in said network element in which the individual fault has occurred,
- means for determining that said test is required and can be executed, and
- a fault recovery function, wherein if said network element can be recovered said recovery is executed automatically.
An automatic network diagnostic method comprising the steps of:
- detecting a fault in a network element;
- making the fault correspond to the fault contents in accordance with a type of the element;
- confirming the fault contents by testing the fault in accordance with the fault contents,
- determining that said testing is required and can be executed, and
- recovering a fault wherein if said network element can be recovered said recovery is executed automatically.
