Modeling and performance prediction are becoming increasingly important issues in the
design and operation of computer communications systems. Complexities in their …

The use of queueing network models to analyze the performance of computer systems is
widespread. Typically the analysis requires certain assumptions to be made. Even under …

Performance modeling is an important topic in capacity planning and overload control for
web servers. We present an M/G/1/K* PS queueing model of a web server. The arrival …

At the present time network communication is an important issue where erratic human
behavior plays a major role, so the problem of network server efficiency analysis comes up …

In this paper we develop and assess the accuracy of two analytical models that capture the
behavior of network hosts when subjected to heavy load such as that of Gigabit Ethernet …

The paper introduces a new analytic queuing model, the N-burst/G/1 model with heavy-
tailed service-time distribution, which captures many of the issues that affect Web servers as …

In applications of queueing network models to computer system performance prediction, the
computational effort required to obtain an exact equilibrium solution of a model may not be …

For a discrete time network of generalized Bernoulli servers with unreliable nodes we derive
the steady state probabilities for the joint queue length vector for all nodes and the …

We construct, analyze and solve models of systems where a number of servers offer
services to an incoming stream of demands. Each server goes through alternating periods of …

The modeling and analysis of system and network performance issues are useful tools in the
development and engineering processes. The analytical models have a high value in the …
