The Road Towards Future Internet

Given the emerging problems of today's Internet, many new Internet architectures have been proposed by the networking community. In general, the new approaches can be categorized into two types: evolutionary approaches and clean-slate approaches. The representative evolutionary solution is IPv6, while representative clean-slate approaches are NDN (Named Data Networking), MobilityFirst, NEBULA, XIA (Expressive Internet Architecture), and SDN (Software-Defined Networking). A comprehensive survey of these approaches is presented. Additionally, a novel network architecture that we recently proposed: ADN (Address-Driven Networking) is described, which intends to address the challenges faced by today's Internet via the flexible and innovative utilization of IP addresses.
