A differentiated service mechanism considering SLA for heterogeneous cluster Web systems
Changhoon Kang, Kiejin Park, Sung-Soo Kim · 2006
As the Web is becoming more widely used as the preferred method for critical information exchange, it is necessary to provide differentiated service mechanisms not only at the network level but also at the Web server level. In this paper, we study performance isolation and admission control concepts of heterogeneous cluster-based Web systems and study the availability of primary-backup Web switches. Due to the types of requests of clients, the SLA (service level agreement) between the clients and the service provider is considered.
