AWSQ: an approximated web server queuing algorithm for heterogeneous web server cluster

A Request Distribution Algorithm for Web Server Cluster

With the explosively increasing of web-based applications’ workloads, Web server cluster encounters challenge in response time for requests. Request distribution among servers in web server cluster is the key to address such challenge, especially under heavy workloads. In this paper, we propose a new request distribution algorithm named llac (least load active cache) for load balancing switch i...

A content-based dynamic load-balancing algorithm for heterogeneous web server cluster

According to the different requests of Web and the heterogeneity of Web server, the paper presents a content-based loadbalancing algorithm. The mechanism of this algorithm is that a corresponding request is allocated to the server with the lowest load according to the degree of effects on the server and a combination of load state of server. Besides, apply a method of random distributing base-p...

Dynamic Scheduling of Web Server Cluster

Web server is recently composed of a server cluster for keeping good quality of services in spite of suddenly rushed connections. LVS (Linux Virtual Server) is one of methods to build server cluster in Linux and it has its own load balancing mechanism [1]. The existing load balancing mechanism, however, reaches the limit often and fails to keep load in balance, in particularly electric commerce...

occwserv: An occam Web-Server

This paper presents ‘occwserv’, the occam web-server. This is a highly concurrent web-server, written in the occam multi-processing language, that supports the majority of the HTTP/1.1 protocol. Dynamic process and channel creation mechanisms are used to create scalable ‘server-farms’, each responsible for a particular webserver function — for example, reading client requests or running CGI pro...
