Design and Implementation of a Scalable Web Cluster System Using a Light-Weight Cluster Control Protocol
نویسنده
چکیده
The need for web services is constantly increasing, while the requirements for web services are getting more and more complicated. Thus, web server systems with ever increasing performance are constantly in need. To efficiently satiate this need, web cluster systems, which have been a topic of much research, have been suggested due to its scalability. In this paper, we design and implement a scalable web cluster system using a light-weight cluster control protocol on the IP layer in the Linux operating system. Experimental results illustrate that our implementation of the web cluster system linearly improves performance as the server nodes increase. We show that although the web cluster control protocol implemented on the IP layer does not support any reliable mechanism, the problem related to packet loss or fault has little effect on the system performance.

Investigation on Reliability Estimation of Loosely Coupled Software as a Service Execution Using Clustered and Non-Clustered Web Server
Evaluating the reliability of loosely coupled Software as a Service through the paradigm of a cluster-based and non-cluster-based web server is considered to be an important attribute for the service delivery and execution. We proposed a novel method for measuring the reliability of Software as a Service execution through load testing. The fault count of the model against the stresses of users ...
متن کاملTarget Tracking Based on Virtual Grid in Wireless Sensor Networks
One of the most important and typical application of wireless sensor networks (WSNs) is target tracking. Although target tracking, can provide benefits for large-scale WSNs and organize them into clusters but tracking a moving target in cluster-based WSNs suffers a boundary problem. The main goal of this paper was to introduce an efficient and novel mobility management protocol namely Target Tr...

This paper describes the motivation, design and performance of web cluster server with self-processing web switch for enhanced packet throughput. The goal of the proposed web cluster server is to provide a framework for building highly scalable, fault-tolerant services using a large cluster of commodity servers. It employs web switches processing packets by themselves while operating at content...
متن کاملA load cluster management system using SNMP and web
Clustered servers for Internet service is a popular solution to cope with the explosive increase in client requests. The high probability of service failure in cluster servers make the cluster management system necessary to provide high availability and convenient administrator control. In this paper, we present the design and implementation of a load cluster management system (LCMS) based on S...
