Abstract

Correlation of network nodes in terms of round-trip-time (RTT) can be quantified by the similarity metric which is defined as the extent to which two source nodes have the same changing trends in terms of RTT to the same destination node. With this definition, the effects of path length, more specifically, the path length ratio that is defined as the ratio of the length of the common path to that of the longer private path, on such correlation is analyzed. Our analysis shows that path length ratios from 1:1 to 8:1 have obviously more positive effects on the upward trend of similarity when the common path load increases or the private path loads decrease and that similarity will get better when path length ratio gets higher while path load combinations remain the same.
