Wavelet compression of network delay measurements
online resource
posted on 2008-01-03, 12:41 authored by Kostas KyriakopoulosKostas Kyriakopoulos, David ParishMonitoring high-speed networks produces a large amount of network performance measurements over a
long period of time making their storage impractical. This paper looks at the Wavelet Transform as a
method of compressing the information describing network delay measurements while maintaining
quality of important signal features. A wavelet coefficient thresholding technique is used along with an
efficient method for storing wavelet coefficients. Experimental results are obtained to compare soft and
hard thresholding techniques by using the mean square error (MSE) statistic and the file size of the
compressed output. In addition, those two techniques are compared against the lossless compression tool
bzip2. Results show that the proposed method achieves 6.5 times more compression than bzip2 while
preserving the peaks and bursty segments of the examined signals.
