Reactive Network Measurement
Vern Paxson and Mark Allman1
Often when assessing complex network behavior a single measurement is not enough to gain a solid understanding of the root causes of the activity. In this project we explore the notion of "measurement" as a process rather than an event.
Our central focus is on reactive measurement (REM), where one measurement's results are used to automatically decide what (if any) additional measurements are required to further understand some observed phenomenon. While reactive measurement has been used on occasion in measurement studies, what has been lacking is (1) an examination of its general power, and (2) a generic framework for facilitating fluid use of this approach.
We believe that by enabling the coupling of disparate measurement tools, REM holds great promise for assisting researchers and operators in determining the root causes of network problems and enabling measurement targeted for specific conditions.
