Flash crowds alleviation network

FCAN (Flash Crowds Alleviation Network) is an adaptive Content Delivery Network that dynamically optimizes the system structure between peer-to-peer (P2P) and client–server configurations as a possible way 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.
While FCAN has been the subject of some research, there are no widespread deployments.
