Sojourn times and Rare Events
"... Abstract: In this paper, we present and analyze three different algorithms for the evaluation of rare event simulation results. They are loosely based on the AA c method, which in turn is an enhancement of the LRE-algorithm, derived from the sojourn time analysis of that algorithm. The AA c method i ..."

Quantiles of sojourn times
, 2004
"... Fast response times and the satisfaction of response time quantile targets are important performance criteria for almost all transaction processing and computer-communication systems. However, they tend to be difficult to obtain in stochastic models, even when the mean value of the response time has ..."

has a relatively simple mathematical expression. Expressions have been obtained for the Laplace transform of the probability density function of sojourn times in many queueing models, including some complex single queues and networks of simple queues. These can sometimes be inverted analytically
Sojourn times in Markov processes
- Journal of Applied Probability
, 1989
"... In a homogeneous finite-state Markov process, we consider the occupation times, that is, the times spent by the process in given subsets of the state space during a finite interval of time. We first derive the distribution of the occupation time of one subset and then we generalize that result to th ..."

Sojourn Times of Brownian Sheet

"... This paper is dedicated to Professor Endré Csáki on the occasion of his 65th birthday. Let B denote the standard Brownian sheet. That is, B is a centered Gaussian process indexed by R2 + with continuous trajectories and covariance structure ..."

Web-Pages Sojourn Times in High Speed Networks
"... Processor Sharing (PS) queuing systems have been historically applied for the estimation of file sojourn times. We present a model for web-pages sojourn times at the session-layer by incorporating the time spent by TCP in its slow-start and congestion avoidance phases. The model is a function of not ..."

Reducing the Variance of Sojourn Times in Queueing Networks with Overtaking
- Forschungsbericht, Preprint-Reihe Nr. 73, Universitat Wurzburg, Institut fur Informatik
, 1993
"... In a queueing network with overtaking, the probabilistic effects entailed by a customer propagate in such a manner that the sojourn time of the same customer in a node visited later is affected. The main effect of overtaking is the dependency of node sojourn times on non-overtake-free paths: the soj ..."

Preventing large sojourn times using SMART scheduling
- Operations Research
, 2005
"... Recently, the class of SMART scheduling policies has been introduced in order to formalize the common heuristic of “biasing toward small jobs. ” We study the tail of the sojourn-time (response-time) distribution under both SMART policies and the Foreground-Background policy (FB) in the GI/GI/1 queue ..."

TABLE OF CONTENTS 4 MESSAGE SOJOURN TIME
"... Abstract—Access Points play an essential role in fault tolerant architectures for mobile computing environments which engage wireless networks. They are the performance bottleneck in the presence of failures and handoffs of mobile stations. Different message dispatch strategies impose different effe ..."

effects on the message sojourn time in Access Points. In this paper, we study five dispatch models which are the basic queueing model, the static and the dynamic processor-sharing models, the round-robin model, and the feedback model. We derive the expected message sojourn time in Access Points under
Bottleneck analysis of discrete time networks: Sojourn times
, 2007
"... For a closed cycle of Bernoulli servers in discrete time with a single bottleneck we prove weak convergence of the suitably rescaled joint queue length vector for all nodes and weak convergence of the suitably rescaled cycle time when the network approaches heavy trac regime. We further investigate ..."

asymptotic dependencies of the sojourn time vector and nd unexpected behaviour of the covariance structure. A technical device for our proofs is a Harrison-type formula for arrival probabilities which is of independent interest.
