Heavy traffic queue length behavior in a switch under the MaxWeight algorithm

Stochastic Systems, 2016
We consider a switch operating under the MaxWeight scheduling algorithm, under any traffic pattern such that all the ports are loaded. This system is interesting to study since the queue lengths exhibit a multi-dimensional state-space collapse in the ...

Variable heavy tails in Internet traffic [PDF]

Performance Evaluation, 2004
This paper studies tails of the size distribution of Internet data flows and their "heaviness". Data analysis motivates the concepts of moderate, far and extreme tails for understanding the richness of information available in the data. The data analysis also motivates a notion of "variable tail index", which leads to a generalization of existing ...

Random Traffic Flow Simulation of Heavy Vehicles Based on R-Vine Copula Model and Improved Latin Hypercube Sampling Method

Sensors, 2023
The rationality of heavy vehicle models is crucial to the structural safety assessment of bridges. To establish a realistic heavy vehicle traffic flow model, this study proposes a heavy vehicle random traffic flow simulation method that fully considers ...
