posted on 2007-10-17, 10:52 authored by Kostas KyriakopoulosKostas Kyriakopoulos, David ParishMonitoring high-speed networks for a long period of time produces a high volume of
data, making the storage of this information practically inefficient. To this end, there
is a need to derive an efficient method of data analysis and reduction in order to archive
and store the enormous amount of monitored traffic.
Satisfying this need is useful not only for administrators but also for researchers
who run their experiments on the monitored network. The researchers would like to
know how their experiments affect the network's behavior in terms of utilization,
delay, packet loss, data rate etc.
In this paper a method of compressing computer network measurements while preserving
the quality in interesting signal characteristics is presented. Eight different
mother wavelets are compared against each other in order to examine which one offers
the best results in terms of quality in the reconstructed signal. The proposed
wavelet compression algorithm is compared against the lossless compression tool
bzip2 in terms of compression ratio (C.R.). Finally, practical results are presented by
compressing sampled traffic recorded from a live network.
