Prof. Roch Guerin of the University of Pennsylvania. Lecture: June 7, 2012 There is no denying the many innovations behind modern networks. From the optical core of the Internet to wireless edges, technology innovation has driven their expansion. The premise of this talk is that while technology innovation is still needed, it faces a vastly different environment; one where economic issues play an equal if not more important role. This manifests itself in at least two major aspects. The first is the presence of an overwhelming incumbent that can at times stymie the deployment of even the best innovations. The "Internet ossification" is a well-publicized instance of this phenomenon. The second is a shift from developing and enhancing connectivity to using it. The explosion of the "app market" is an obvious example, but it also manifests itself in subtler and equally important ways. In particular, while a ubiquitous network opens-up access to vast untapped storage, computation, and communication resources, understanding how to incentivize the owners of those resources is key to leveraging them. In this talk, I will try to elucidate both aspects and some of the techniques that can be used to explore them. First, through the review of a case-study of the challenges faced by IPv6 in replacing IPv4 as the dominant Internet protocol. Second, through the example of a simple service where user resources are used to expand/complement the network. The deployment of such a service illustrates the complex interactions and dependencies that can arise, and how they affect both the adoption and the pricing of the service.
