چکیده

Server responsiveness and scalability are more important than ever in today’s client/server dominated network environments. Recently, researchers have begun to consider cluster-based computers using commodity hardware as an alternative to expensive specialized hardware for building scalable Web servers. In this paper, we present performance results comparing two cluster-based Web servers based on different server infrastructures: MAC-based dispatching (LSMAC) and IP-based dispatching (LSNAT). Both cluster-based server systems were implemented as application-space programs running on commodity hardware. We point out the advantages and disadvantages of both systems. We also identify when servers should be clustered and when clustering will not improve performance.

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...

Scalable load balancing on distributed web servers using mobile agents

Distributed web servers on the immensely expanding Internet require high scalability and availability to provide efficient services to millions of clients on the web. To provide rapid responses to enormous number of client requests, load balancing is an important technique to evenly distribute the requests to web servers. In this paper, we propose a framework called MALD (Mobile Agent based Loa...

DISH - Dynamic Information-Based Scalable Hashing on a Cluster of Web Cache Servers

Caching web pages is an important part of web infrastructure. The effects of caching services are even more pronounced for wireless infrastructures due to their limited bandwidth. Medium to large-scale infrastructures deploy a cluster of servers to solve the scalability problem and hot spot problem inherent in caching. In this report, we present Dynamic Information-based Scalable Hashing (DISH)...

Enabling Content-Based Load Distribution for Scalable Services

We argue that using information content of individual client requests to distribute load across a cluster of workstations or PCs has many attractive properties, and describe how current Internet standards make content-based load distribution difficult. We discuss several approaches to achieve content-based load distribution for large scalable services such as WWW servers. We illustrate the adva...
