Experimental queueing analysis with long-range dependent packet traffic

A. Erramilli, O. Narayan, W. Willinger
1996 IEEE/ACM Transactions on Networking  
Of particular interest in packet traffic modeling is a property called long-range dependence (LRD), which is marked by the presence of correlations that can extend over many time scales.  ...  In addition, we give conditions under which the use of compact and simple traffic models that incorporate long-range dependence in a parsimonious manner (e.g., fractional Brownian motion) is justified  ...  Narayan acknowledges the support of the Society of Fellows at Harvard University and also the hospitality of AT&T Bell Laboratories.  ...

The Shape of the Loss Curve and the Impact of Long-Range Dependence on Network Performance

Michel Mandjes, Nam Kyoo Boots
2004 AEU - International Journal of Electronics and Communications  
Empirical studies showed that many types of network traffic exhibit long-range dependence (LRD), i.e., burstiness on a wide variety of time-scales.  ...  To assess this issue, we consider a generic source model: traffic generated by an individual user is modeled as a fluid on/off pattern with generally distributed on-and off-times; LRD traffic is obtained  ...  Finally, it is calculated what performance is realized if this traffic stream feeds into the network -the type of models used are usually queueing models. Long-range dependence.  ...
