James Roberts, chercheur senior à SystemX a animé un séminaire, le jeudi 2 octobre à Nano-INNOV (bâtiment N2,amphi 34) de 14h à 15h, sur le thème :
« Trading off bandwidth for memory in a future information-centric Internet »
Résumé [en anglais]
Perceived limitations of the 40-year-old IP architecture, coupled with ever-increasing demand for text, audio and video content have spurred proposals for a new, information-centric Internet architecture. We illustrate this vision by outlining the principles of the so-called named data networking (NDN) architecture, currently under definition by researchers throughout the world. Whether or not it proves possible to overcome inertia and radically change the Internet protocols by imposing a new architecture, it is clear that the technical and economic structure of the network must evolve. It is important, in particular, to exploit an increasingly favourable memory for bandwidth tradeoff by storing copies of popular content closer to end-users. We discuss the way this cost optimization can be quantified and discuss its consequences on the likely structure of the future Internet.
