The growing demand for Web and multimedia content accessed through heterogeneous devices requires the providers to tailor resources to the device capabilities on-the-fly. Providing services for content adaptation and delivery opens two novel challenges to the present and future content provider architectures: content adaptation services are computationally expensive; the global storage requirements increase because multiple versions of the same resource may be generated for different client devices. We propose a novel two-level distributed architecture for the support of efficient content adaptation and delivery services. The nodes of the architecture are organized in two levels: thin edge nodes on the first level act as simple request gateways towards the nodes of the second level; fat interior clusters perform all the other tasks, such as content adaptation, caching and fetching. Several experimental results show that the Two-level architecture achieves better performance and scalability than that of existing flat or no cooperative architectures.
