Overview
In this project we study and investigate network anomaly detection algorithms [1] [2] [3] for Internet Paths. We also develop a Decision Theoretic Approach based on our observations about the characteristics of the performance measurements statistics obtained from the IEPM-BW project.
To study and compare the algorithms we use the data sets collected by IEPM-BW spanning approximately 2 years (i.e. 2006 - 2008). The Internet paths observed were the links between Stanford Linear Accelerator Center (SLAC) and the following sites:
- San Diego Supercomputing Center (SDSC) USA,
- Oak Ridge National Laboratory (ORNL) USA,
- European Organization for Nuclear Research (CERN) Geneva, Switzerland,
- Forschungszentrum Karlsruhe (FZK) Germany,
- Deutsches Elektronen- Synchrotron (DESY) Germany and
- University of Toronto (UTORONTO) Canada.
Data Sets
The data sets used in the study may be downloaded from the links listed below. Latest performance statistics may be accessed from here.
