Admission Control Schemes Guaranteeing Customer QoS in Commercial Web Sites

Summary, in English

Many commercial web sites, as web stores, have recently experienced performance

problems due to the growth of Internet trading. One way to improve a site’s

performance during overload is to introduce admission control mechanisms. In

this paper we develop and investigate two admission control schemes specifically

for distributed commercial web sites. One of the schemes is request-based

and the other one is session-based. A queuing network model is used to investigate

a distributed site representing a web store. We find that both schemes

improve the site’s performance during overload. However, while the sessionbased

control scheme guarantees a good customer QoS, the request-based

scheme generates a large amount of so called angry customers.
