Forwarding Accountability: A Challenging Necessity of the Future Data Plane

Forwarding accountability mechanisms pinpoint the sending/forwarding properties of traffic to the entities that send and forward the traffic along a path. In this paper, we take flooding attacks as a use case and describe a proposal to hold senders accountable for the sending rates of their flows. Furthermore, we describe the corresponding challenges, potential solutions, and briefly present the literature in the area of forwarding accountability.
