Problem determination using probing
First Claim
Patent Images
1. An apparatus for diagnosing problems in multiple node networks using probing technology, the apparatus comprising:
- an arrangement for determining a candidate probe set;
an arrangement for determining which problems can be diagnosed by the candidate probe set;
an arrangement for finding small probe sets which can diagnose the same problems as the candidate probe set; and
an arrangement for diagnosing problems in the multiple node network based upon a success or failure of probes in the small probe sets.

Abstract
The deployment of probing technology for the purpose of problem determination in a server or network element is disclosed. One can actively select which probes to send in order to be able to diagnose problems which one is particularly interested in, allowing for greater flexibility and efficiency. The extra load imposed on a network by the use of probes is small, especially if the algorithms described in this disclosure are used.
