Open Queueing Networks in Heavy Traffic

Mathematics of Operations Research, 1984
This paper presents heavy traffic limit theorems for the queue length and sojourn time processes associated with open queueing networks. These limit theorems state that properly normalized sequences of queue length and sojourn time processes converge weakly to a certain diffusion as the network traffic intensity converges to unity. The limit diffusion

Queue Disciplines in Heavy Traffic

Mathematics of Operations Research, 1982
A general method of analyzing the behavior in heavy traffic of queues with different impartial queue disciplines is described. There are many possible limiting waiting time distributions though all are mixtures of negative exponentials. The exponential distribution itself, however, shows a degree of robustness to departures from the “first come first ...

Detecting Heavy Change in the Heavy Hitter distribution of network traffic

2011 7th International Wireless Communications and Mobile Computing Conference, 2011
The increasing number of network attacks causes growing problems for network operators and users. Thus, detecting anomalous traffic is of primary interest in IP networks management. In this paper we present a novel method for network anomaly detection, based on the idea of discovering Heavy Change (HC) in the distribution of the Heavy Hitters in the ...

Optimal capacity allocation for heavy-traffic fixed-cycle traffic-light queues and intersections [PDF]

Transportation Research Part B: Methodological, 2023
Setting traffic light signals is a classical topic in traffic engineering, and important in heavy-traffic conditions when green times become scarce and longer queues are inevitably formed.

Role of traffic in atmospheric accumulation of heavy metals and polycyclic aromatic hydrocarbons

Atmospheric Environment, 2012
Traffic related emissions have been recognised as one of the main sources of air pollutants. In the research study discussed in this paper, variability of atmospheric total suspended particulate matter (TSP), polycyclic aromatic hydrocarbons (PAH) and ...

Queueing Simulation in Heavy Traffic

Mathematics of Operations Research, 1992
The heavy traffic behavior of a number of standard queueing simulation procedures like sample averaging and regenerative simulation is studied. In particular, limit theorems based upon Brownian approximations are given in a double limit with both the sample size t tending to infinity and the traffic intensity ρ tending to one.

Storage-Limited Queues in Heavy Traffic

Probability in the Engineering and Informational Sciences, 1991
This paper models primary computer storage in the context of a general (GI/GI/l) queueing system. Queued items are described by sizes, or storage requirements, as well as by arrival and service times; the sum of the sizes of the items in the system is the occupied storage.

Scheduling in polling systems in heavy traffic

ACM SIGMETRICS Performance Evaluation Review, 2013
We consider the classical cyclic polling model with Poisson arrivals and with gated service at all queues, but where the local scheduling policies are not necessarily First-Come- First-Served (FCFS). More precisely, we study the waitingtime performance of polling models where the local service order is Last-Come-First-Served (LCFS), Random-Orderof ...

Queue Management for the Heavy-Tailed Traffics

2010 International Conference on Broadband, Wireless Computing, Communication and Applications, 2010
The purpose of this research is to design the new queueing algorithm effectively controlling the heavy-tailed traffics based on the comparison between the performance of the passive queue algorithm and that of the active queue algorithm. We adopted the tail-drop algorithm for PQM and the Random Early Detection (RED) for AQM, and conducted the ...
