Integrated data flow delivery with built-in mass storage

The massive big data transfer requirements in the cloud age are posing unprecedented challenges on todays´ network infrastructure. Delivering data in a cost effective and scalable manner is of critical importance to support the continued growth of cloud services. In this paper, we revisit the problem of delivering large data on top of dynamic circuit switched networks, with a particular focus on how it can be used together with packet switching in an integrated data delivery model. We argue that the Software Defined Networking (SDN) concept and flow based switching are crucial to realize scalable and energy efficient integrated data delivery. We propose to use built-in or public storage to resolve contentions between large data flow transfers.
