Dynamically Reconstructive Web Server Cluster Using a Hierarchical Grouping Mechanism.
Sung Il Lim, Myong-Soon Park · 2003
Abstract: The Internet is quickly growing and people who use the WWW are increasing exponentially. So, companies which offer Web Service want to service to clients during 365*24*60. Therefore they use the cluster system for the availability and the performance. The previous works have made the dispatcher do static position. So, if a node in the system is failed the total system results in crash. We need to make it do dynamic position as like SASHA (Scalable Application-Space Highly-Available) Architecture. SASHA Architecture is composed of COTS, Application-Space Software, Agent and Tokenbeat protocol for system administration. Because it composes nodes in system by a virtual ring, the system administration’s overhead happened. Our paper will propose improved fault Detection and Reconfiguration performance in SASHA Architecture. 1
