Despite the steady and significant increase in Internet traffic, today's Internet topologies are stable, reliable, and – underutilized. This is mainly due to the proven practice to overprovision Internet links, – often up to seventy percent, thus allowing for accommodation of unpredictably large packet flows, while keeping the network stable and resilient against attacks and failures. Even with major operational benefits, the practice of overprovision is known for its high capital and operational expenses. At first glance, dynamic optical circuits can address the downsides of Internet overprovision, as they can be setup to bypass any congested or faulty IP links and they are comparably less expensive. However, the two networks -- optical and Internet, have evolved as two fundamentally different and separately managed ecosystems, and cannot easily operate in harmony. In this talk, I will discuss why past approaches to deploy dynamic optical circuits have not been widely adopted for IP routing, – from the point of view of network management, and present our research ideas on how Internet can effectively use optical circuits. I will talk about the importance of new systems research and present new directions in theoretical studies in this field, including an analysis of the effects of dynamic optical circuit setup on IP routing. Finally, I will give a practical outlook from our EU Project ONE (www.ict-one.eu <http://www.ict-one.eu>), focusing on network management aspects of optical network and the Internet coordination.
