Abstract

With the rapid spread of information and ubiquitous access of browsers, flash crowd, a sudden, unanticipated surge in the volume of request rates, has become the bane of many Internet websites. This paper models and presents FCAN, an adaptive CDN network that dynamically optimizes the system structure between peer-to-peer (P2P) and client-server(C/S) configurations to alleviate flash crowds effect. FCAN constructs P2P overlay on cache proxy layer to distribute the flash traffic from origin web server. It uses policy-configured DNS redirection to route the client requests in balance, and adopts strategy load detection to monitor and react the load changes. Our preliminary simulation result shows that the system is overall well behaved, which validates the correctness of our basic design and points the way for the future research.
