An adaptive load balancing scheme for web servers

Abstract

This paper describes an overload control scheme for web servers which integrates admission control and load balancing. The admission control mechanism adaptively determines the client request acceptance rate to meet the web servers' performance requirements while the load balancing or client request distribution mechanism determines the fraction of requests to be assigned to each web server. The scheme requires no prior knowledge of the relative speeds of the web servers, nor the work required to process each incoming request.

Cloud Computing—Effect of Evolutionary Algorithm on Load Balancing

“…Hooks law could also connect the stress and strain in three dimensional objects. In this sense, k could be explained as a 3 × 3 matrix that will be multiplied by movement of d in three dimensions to represent the applied force [13,14]. Therefore the force vector will be depicted by Eqs.…”

Multi-dimensional credentialing using veiled certificates: Protecting privacy in the face of regulatory reporting requirements

“…If individuals create multiple VCs per month compared to a single certificate per year, as would be expected if using a traditional certificate, the CA must scale its operations accordingly. However, since each certificate can be processed independently, the CA's computational burden can be accelerated using parallel multi-processing, as is common with server farms (Aweya et al, 2002;Wolf and Yu, 2001).…”

Flow Based Load Balancing: Optimizing Web Servers Resource Utilization

“…Thus, load balancing mechanisms are necessary to distribute requests among multiple nodes offering the same service (Aweya et al, 2002). Hence, the scalability of the service being offered is proportional to the efficiency of the load balancing algorithm used to guarantee an optimal utilization of available resources.…”
