Abstract
A novel dynamic and active CDN architecture based on active network (ACDN) is proposed. The programmable character of active network makes it easier and quicker to configure new replica servers as well as deploy new policies on demand. A genetic algorithm (GA) based replica server placement optimization algorithm is designed and implemented, as well as active anycast-like user request routing method and policy-based content distribution mechanism. To demonstrate the utility of ACDN model, we implemented a prototype of ACDN, which using extended ANTS active network execution environment. The results show that our approach is reasonable and can satisfied access delay of web application.
