Efficiency of Server Task Queueing for Dynamic Load Balancing

Load Balancing Approaches for Web Servers: A Survey of Recent Trends

Numerous works has been done for load balancing of web servers in grid environment. Reason behinds popularity of grid environment is to allow accessing distributed resources which are located at remote locations. For effective utilization, load must be balanced among all resources. Importance of load balancing is discussed by distinguishing the system between without load balancing and with loa...

Analysis & Minimization of the Effect of Delay on Load Balancing for Efficient Web Server Queueing Model

A 2 Level Dynamic Scheduling Method for Real Time Tasks on Homogeneous Distributed System

A distributed system is a collection of independent computers that appears to its users as a single coherent system. Depending on job arrival rate some of the computing nodes may become overloaded while some other nodes may sit idle. The imbalance in load distribution may affect overall system performance. So proper task scheduling algorithm is needed. Real time task scheduling algorithm must t...

Boosting the Throughput of a Multi-server System via Adaptive Task Replication

The throughput (rate of task completion) of a multi-server system is typically the sum of the service rates of individual servers. In this paper we demonstrate how task replication can result in a higher throughput, and we seek to find the fundamental limit of this throughput boost. Several recent works have studied queueing systems where tasks are replicated at multiple servers, and the copies...

Web Delay Analysis and Reduction by Use of Load Balancing of a Dispatcher-based Web Server Cluster

The loading of web servers can be very heavy and a delay in accessing certain Web sites can be substantial. Hence, the reduction of web delay is one of the important topics of research for improving the quality of service of Web pages. Thus, in this paper, we propose the web delay analysis and the web delay reduction by using load balancing coupled with the dispatcher-based approach. First, we ...
