Abstract

The Flash crowds are rapid increase in access to contents of web sites, which makes the web sites inaccessible, leaving the clients with unsatisfied requests. The major shortcoming of flash crowds researches is that they do not assist vital resizing feature of a cloud of the surrogates; the surrogates involved in the alleviation process do not change from the start to the end of flash crowds. Our system, FCAN (Flash Crowds Alleviation Network) is a system to provide resources to web sites to overcome flash crowds. A main feature of FCAN is its dynamically resizing feature, which can adapt to request load of flash crowds by enlarging or shrinking a cloud of surrogate servers used by the web sites. In this paper, we present a new feature of FCAN to support multiple servers which experience different flash crowds simultaneously, and show experiment results with real web log data provided by Live Eclipse 2006.
