| 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 ISP practice to overprovision IP links, – often up to seventy percent, thus allowing for accommodation of unpredictable flows, while keeping the network stable and resilient against attacks and failures. Even with major benefits, the practice of overprovision leads to high capital and operational expenses, as well as higher energy consumption. At first glance, dynamic optical circuits can address the downsides: optical circuits can be setup to bypass any congested or faulty IP links and are one of the “greenest” technologies. However, the two networks — optical and Internet, have evolved as two fundamentally different and separately managed systems, 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, and also give a practical outlook from our EU Project ONE (http://www.ict-one.eu). |
