Abstract	:	In this thesis, we study the cause and impact of burstiness in computer networktraffic. A connection-level analysis of traffic at coarse time scales (time scales greaterthan a round-triptime) reveals that a single connection dominates during the periodof the burst. The number of dominating connections that cause bursts is found tobe a small fraction of the total number of connections. Removing the burst causingconnections from the traffic yields a trace whose marginal is close to a Gaussian. Thisobservation motivates a network traffic model comprised of two components, namelythe Gaussian part and the bursty part. The Gaussian part of the traffic models theaggregate of majority of the connections, whereas the bursty part models the behaviorof few dominant connections that transmit data a t unusually high rates. The Gaussiancomponent imparts long-range-dependence (LRD) to the traffic, whereas the burstycomponent gives rise to spikiness. We argue that heterogeneity in bottleneck linkspeeds gives rise to burstiness, and heavy tailed connection durations results in LRD.We perform simulations in ns to validate the proposed-....,....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
