7.4. Summary

This chapter looked at the OSI fault management requirement for the reporting of network faults. It examined the traditional symptomatic methods for doing this, and commented on some of their shortfalls. The idea of intelligent systems was introduced, and their use in creating intelligent network monitoring utilities was discussed.

The need for the topology information obtained in Chapter 4 as a pre-requisite knowledge base for such an intelligent system was discussed, as was the recursive nature employed by systems aimed at detecting network faults. The testing of various services was examined, and it was pointed out that this may be a good application for neural networks.

Fault reporting was also discussed, particularly the need to generate concise, accurate fault reports. A strategy for achieving this through the use of an expert system was introduced.
