ActiveCDN: Cloud Computing Meets Content Delivery Networks

Srinivasan, Suman Ramkumar; Lee, Jae Woo; Batni, Dhruva L.; Schulzrinne, Henning G.

Content delivery networks play a crucial role in today's Internet. They serve a large portion of the multimedia on the Internet and solve problems of scalability and indirectly network congestion (at a price). However, most content delivery networks rely on a statically deployed configuration of nodes and network topology that makes it hard to grow and scale dynamically. We present ActiveCDN, a novel CDN architecture that allows a content publisher to dynamically scale their content delivery services using network virtualization and cloud computing techniques.
