The title of this report, "Everything over IP, IP over Everything", refers to the convergence role of the Internet Protocol. In this report, we illustrate how IP has become the "de facto" networking protocol, with particular emphasis on economical aspects. After a brief review of the wide range of services running over IP today, we examine the most used core networking technologies such as DWDM, SONET, ATM, 10-Gigabit Ethernet, and MPLS, and how future networks dedicated to IP traffic will lead to a contraction of layers. Finally, we review the challenges faced by IP, in terms of scalability, security, and quality of service, and propose an outlook for the technology’s use in future networks based on economical grounds.
