an acceptable load in the system. This paper presents how admission control mechanisms can be designed with a combination of queueing theory and control theory. In this paper we model an Apache web server as a G/G/1-system and then design a PI-controller, commonly used in automatic control, for the server

of Distributed Cooperative Apache (#########)web server. In this paper, we describe the unique features of the ######### system (1) to migrate and replicate documents among cooperating servers, (2) using dynamic hyperlink generation to distribute requests for documents to balance the load, and (3) to maintain

In this paper we focus on the relationship between the error rate which is one of the representative reliability measures in Apache web servers and the system parameters which reflect on the web server's system performance, and develop a probability model to describe it. More specifically, we

. This combination of denying unnecessary access and allowing required access results in providing web server functionality while limiting damage. To demonstrate this, we hosted the Apache web server on Security-Enhanced Linux, an operating system that enforces a mandatory access control policy. By tailoring

Abstract. Properly optimizing the setting of configuration parameters can greatly improve performance, especially in the presence of changing workloads. This paper explores approaches to online optimization of the Apache web server, focusing on the MaxClients parameter (which controls the maximum

The main theme of this paper is to find the Distributed Data Transaction of an Apache web server using bulk service rule. We obtain the parameter of service rate, Arrival rate, Expected waiting time and Expected Busy period. The inter arrival and inter service of HTTP request is assumed to Poisson

Performance of Web servers is critical to the success of many corporations and organizations. However, very few results have been published that quantitatively study the server behavior and identify the performance bottlenecks. In this paper we measure and analyze the behavior of the popular Apache

Apache Web server on a uniprocessor system and a 4-CPU SMP (Symmetric Multi-Processor) system running the IBM AIX operating system. Using the AIX built-in trac-ing facility, we obtained detailed information on ker-nel events and system activities while running Apache driven by the SPECweb96 and the Web
