PERFORMANCE MEASURES FOR INTERNET SERVER BY USING M/M/M QUEUEING MODEL

Queueing Model Based Network Server Performance Control

Controlling the timing performance of a network server is a challenging problem. This paper presents a Queueing Model Based Feedback Control approach to keep the timing performance of a network server close to the service level specification. We show that in an instrumented Apache server, combining feedback control with a queueing model leads to better tracking of QoS specifications than with f...

Computation of Bounds and Performance Guarantees for Client-Server Systems Using a Queueing Network Model

Multiclass Queueing networks have been suggested by a number of researchers for the performance engineering of client-server systems. A number of implementation mechanisms such as software servers, locks in transaction processing, and critical sections make the application of existing analytic methods for queueing networks difficult for the performance analysis of client-server software and sys...

Performance Measures of Mobile Ad Hoc Networks Using Queueing Models

A multi - server queueing model with

In this paper we analyse a multi-server queueing model with locking. The model is motivated by a situation we encountered at a maintenance facility for trains. Maintenance is done at parallel tracks, where each track ooers space to two trains. Trains can enter and leave the tracks from one and the same side only. This gives rise to locking of the front train: in order to leave the maintenance t...
