Resilience: Widerstandsfähigkeit des Internets gegen Störungen - Stand der Forschung und Entwicklung

Although todays internet operates remarkably well, it cannot be considered as resilient. One of the reasons is the fact that the requirements at the time when the net was developed have since evolved significantly. In this article, we first discuss the notion of "resilience". Then we describe the weak points of todays Internet. The main contribution of this paper is a broad overview on network resilience technologies that are either already in use in todays Internet, or that are being developed or about to be deployed in the mid to near future.
