LAN Performance Ratings Using Fuzzy Set Theory

Free registration required

Executive Summary

A single dimension cannot quantify or properly express the performance of a LAN. It is very difficult to interpret LAN metrics without knowing what application (users) are involved. LAN performance measurement metrics are resource usages, processing delays, throughput, availability, fairness of measured data, and communigram. LAN policies need to be frequently updated based on feedbacks from implementation of previous policies. These feedbacks are always stated in the form of ordinal ratings, e.g. "High speed", "Average performance", "Good condition". The Different people can describe different values to these ordinal ratings without a clear-cut reason or scientific basis.
