A network router that marks packets to signal congestion should do so fairly. We propose a deenition of fairness, using ideas from eeective band-width theory and economics. Our deenition measures both the level of congestion at a router and the contribution of each ow to that congestion, taking into account the ow's burstiness. We then use large deviations to analyse marking algorithms such as ...

A Quantitative View of Short Utterances in Daily Conversation: A Case Study of Thats right, Thats true and Thats correct
