Analyzing Cross Traffic Effects on Packet Trains using a Generic Multihop Model


Publication Type:

Report - MRTC




To develop accurate measurement methods based on active probing, an understanding (at the packet level) of how probe flows and cross traffic flows interact with each other is required. Several existing measurement methods rely on packet-train probing. In this paper, we use a multi-hop model to describe how cross traffic packets affect a packet train.When one packet within a packet train is delayed, the dispersion (i.e. packet separation) of at least two (and possibly more) probe packets will change. Furthermore, the dispersions are not independent, which may bias dispersion average calculations. Many methods use dispersion averages in the calculation of bandwidth estimates and predictions.We have identified and analyzed three major cross traffic effects on packet trains - chain, quantification, and mirror patterns. Experiments have been performed in a testbed to explore these patterns.In histograms of delay variations for adjacent probe packets, these patterns are manifested as different identifiable signatures.
