A Tubeless Internet (David Reed) (presentation, video) top
US Sen. Ted Stevens has stated that "the *Internet* is not something you just *dump* something on. It's not a *truck*. It's a series of *tubes*..." Such confusion between the Internet and the particular physical infrastructures that underly it is far too common, and a source of problems that are having a more and more serious impact on both ends of the hourglass - its implementation and its utility. It may well be the case that many researchers share this confusion, and spend their time fighting the "last war". As we look at the future of the core Internet Concept, it faces a number of challenges - particularly in the areas of mobility, multiconnectivity, adaptability, context-awareness, and adaptability - that cannot be addressed in a metaphorical framework that confuses the tubes with the messages. At the same time, the role of the Internet in our culture and our world has expanded beyond Remote Login and Distributed Computing to embed notions of persistent relationships among collections of humans and devices, as well as dynamic and real-time support of crucial man-machine systems. Given that evolutionary path, the core challenge is not to make the Internet of the past more /efficient/, but to expand the architectural framework of the Internet to encompass these new challenges. This talk discusses some principles for approaching those challenges, and some practical steps that can address them.

Can we imagine a different network? (Dave Clark) (presentation, video) top
The challenge to conceive a new Internet has now been translated into active research, and some interesting ideas are beginning to emerge. While it is too soon to claim that we see a proposal that is complete, consistent, and responsive to the full range of requirements, we can draw some sketches, and outline some alternatives and some missing pieces. This talk will present one person's view of what the shape of this design space might be, looking (often superficially) at issues across layers from packets and forwarding to application support services.

Emerging Wireless Technologies and the Future Internet (Dipankar Raychaudhuri) (presentation, video) top
Wireless and mobile devices are proliferating at a remarkable rate, and will inevitably have a significant transformative effect on the architecture of the global Internet. In this talk, we consider several emerging wireless scenarios (ad hoc/mesh, sensor, vehicular, cognitive radio) and identify related new protocol and network service requirements. A specific mobility-oriented end-to-end protocol architecture (the Rutgers/UMass "cache-and-forward (CNF)" network) is outlined as an illustrative example of exploratory "clean-slate" projects in this area. Experimental research challenges associated with at-scale evaluation and validation of new protocol architectures such as CNF are discussed. Illustrative examples of experimental wireless platforms and programmable network testbed implementations are given from our ongoing work with the ORBIT Radio Grid at WINLAB. Recent proof-of-concept results for wireless virtualization and wired network testbed (PlanetLab, VINI) integration are described briefly. The talk concludes with a summary of wireless features and capabilities planned for NSF's GENI future Internet research infrastructure.

GENI Ecosystem: From Instrument to Architecture (Larry Peterson) (presentation, video) top
GENI is being proposed as an instrument that the networking and distributed systems community can use to validate new network services and architectures, but beyond this narrow definition, there is a larger "GENI Ecosystem" in which the research and instrument are more intimately intertwined. This talk will expand on this perspective, and describe ways in which the GENI Ecosystem is already alive and well.

GENI Overview and the GENI Project Office (GPO) (Chip Elliott) (presentation, video) top
GENI is envisioned as a large-scale facility to explore radical designs for a future global networking infrastructure. We briefly sketch GENI as currently envisioned, then introduce the GENI Project Office (GPO) which has recently assumed responsibility for planning and constructing GENI. We believe the whole community will pitch in and build GENI together. Our vision is for a very lean, fast-moving GPO, with substantially all design and construction work performed by academic and industry research teams. We'd like the community to start building prototypes immediately, within a GENI project framework that is open, transparent, and broadly inclusive.

Networked Information Applications and Future Internet Developments (Cliff Lynch) (video) top
In this talk I'll look at the interplay between potential network-level technical developments and the broader networking information applications environment. These include the potential availability of "storage cloud" distributed secure storage facilities in the network and their implications; the pros and cons of geo-location services, and similiar services to determine national and/or institutional affiliations; and the need for better dynamic capability models in an internet where node mobility is a fundamental property. Finally, I'll focus at some length between the interests that have been expressed in greater security, privacy, and robustness for the future internet on one side, and the offsetting social concerns about invasive and universal surveillance, digital rights management excesses and other developments
