Keynote I

Title: Placing network coding in the network.

Speaker: Muriel Médard, MIT, USA

Muriel Médard

Room: Independence B

Abstract: While the flexibility of network coding allows us to consider its introduction in many different ways, a consensus regarding the most beneficial placement in the network, both in terms of layers and of physical location in the network, has not yet emerged. In this talk, we provide some case studies of introduction of network coding at different layers and at different nodes in the network. We consider implementations of network coding at the transport layer and the MAC layer. Using these examples, we distill some possible architectural principles and posit that introduction of coding at several layers simultaneously may provide cumulative gains. We argue that coding at several layers and in several nodes can yield cumulative benefits without the need for explicit cross-layer or inter-node coordination.

13:30 - 15:00

Panel I: Data Center Networks
This panel will discuss challenges and potential solutions for designing high-speed, reliable data center networks. A single Web search at a data center can involve hundreds of hosts, which makes it important to support fast, reliable, and secure intra-datacenter communications. A high bandwidth network is necessary to support large-scale MapReduce/Hadoop style (offline) data analysis computations. Commercial data center networks typically use Ethernet-switched and/or IP-routed networks, while InfiniBand is popular in scientific data centers for their lower latency. New technologies such as hybrid packet/circuit optical networks, research solutions such as VL2, and other approaches that go beyond 100G are being explored. In parallel, standardization efforts include IETF TRILL and IEEE 802.1Q shortest-path bridging.

Keynote II

Title: Locating Mobile Devices Indoors: Opportunities, Theory, and Practice

Speaker: Jack Brassil, Hewlett-Packard Laboratories, USA

Jack Brassil

Room: Independence B

Abstract:The Global Positioning System (GPS) revolutionized navigation, and the introduction of GPS receivers in mobile phones pushed that revolution into our hands. But many of us spend up to 90% of our time indoors, often out of reach of satellite and macrocell signals. Despite the great utility and promise of context-aware, site-specific services and decades of research on localization technologies few indoor positioning systems are deployed today, even in heavily populated public spaces. I argue that the confluence of several technologies (e.g., smartphones, sensors, small cells) suggest that indoor positioning system deployments will now accelerate quickly. I will share our observations in developing indoor localization systems using enterprise Radio Access Networks, and discuss the challenges both researchers and practitioners face as conventional enterprise data networks are re-cast to embrace Bring Your Own Devices (BYOD) and the increased presence of mobile network operators.

Keynote III

Title: Next Steps towards Internet-optical Service Convergence: A Network Management Perspective

Speaker: Admela Jukan, Technische Universität Carolo-Wilhelmina zu Braunschweig (Brunswick), Germany

Admela Jukan

Room: Independence B

Abstract: 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 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 (, focusing on network management aspects of optical networks and the Internet coordination.
