Title: Re-architecting the Internet: will insights from the past help shape the future?

Abstract:

In over 40 years since the birth of the Internet, the drivers of the initial Internet architecture and protocols design (namely, traffic patterns, mobility needs, supported services, economic benefits and committed stakeholders) have dramatically changed. Network software and protocol extensions have allowed the Internet to incrementally adjust to new contexts and drivers. But, these incremental extensions are now so deeply engrained in the original design, that they have become de facto obstacles to a radical, clean slate innovation. To overcome this Internet protocol “ossification”, in the last decade the research community has been challenged to “rethink” the Internet architecture. This has produced new designs and new ideas, including but not limited to, content centric networking, and software defined networks. Future Internet Architecture designs are today closely scrutinized, investigated, and debated. This panel contributes to such debate, taking however a somewhat unusual perspective and approach. It proposes to bring together the experience and insight of early Internet designers, with the positions of today’s leading researchers committed to re-architect the Internet. Can the pioneers share with us the rationale for the choices they took, the retrospective insights on decisions they made, or the lessons they learned? Can their message help the new Internet designer generations to address the current challenges and inspire future research? Which pitfalls should they avoid as they prospect the future Internet? In essence, how can lessons and insights from the past help us shape the Internet of the future?

PANEL 1

Room: Sala 500

Title: Green Communications: Can We Achieve Load Proportional Energy Use?

Abstract:

Historically, network equipment was not designed with power adaptation operation capabilities and remained powered at near the maximum rating for a given configuration, often with less than 15% variation with load. Load proportional energy use therefore is an important step towards improved efficiency. In mobile and fixed access networks power adaptation methods are already finding use. There are two general strategies toward achieving load proportionality: one is to adapt the hardware operation in speed and/or voltage in response to the traffic load; and the second is to power off or put to sleep components or entire line cards and systems. Placing equipment to sleep often provides the best energy reduction, but comes at a cost in terms of wake up times, traffic disturbance during transitions, and overhead requirements. Rate adaptation can be far more flexible, but may have limited benefit and in some cases can incur performance penalties. Much research has been dedicated to these issues recently. This panel will address the broad question of what the prospects are for these technologies to impact communication networks from access to the core and considering mobile and fixed systems.

Title: Software Defined Networking: which way forward?

Abstract:

Most observers and analysts concur in considering Software Defined Networking (SDN) as the 2012 star: lots of company fundings and acquisitions, and plenty of ink poured on terms such as openflow, network operating systems, control/data plane separation, network function virtualization, network abstractions, and so on. Still, it is fair to say that an hectic debate is widely open on what software networking is (or should be), and what business benefits can it bring about. Yes; (almost) everyone agrees that SDN will, in a way or another, shape the long-term future of networking. Nevertheless, widely differing opinions emerge when discussing about the timing and features of such an evolution. Will it emerge as quick and natural as some do claim, or will it be a slow and exhausting journey, rich of resistances and hurdles? Which trade-offs and specific technical choices (and their devil in the details) will candidate to concretely pave such path? To shed some light on these issues (or perhaps to further exacerbate diverging visions?), the panel assembles renowned experts representing a wide range of SDN business and academic player. Expect a lively debate, and get ready with your questions!
