OSDN: A Novel Platform for Service Distribution through Overlay Routing

While a variety of routing algorithms have been invented for overlay networks, only a few studies focus on the placement problem of overlay nodes. However, the performance of overlay routing always depends on the routing policy of the underlying Internet, such as BGP routing. According to the BGP routing policy, the result routing path heavily depends on the locations of the two end nodes. By placing overlay nodes into selected AS (autonomous system) domains, the overlay network could be more efficient in service distribution than the traditional CDN (service distribution network) could be. Thus we propose OSDN (Overlay Service Distribution Network) as a novel platform to build connection between content service providers and end users from every corner of the Internet.
