Using Packet Symmetry to Curtail Malicious Traffic

This paper argues that a key omission from the original Internet architecture was that of packet dynamics. The historical obsession with end-to-end design has resulted in connection signalling, flowand congestion-control loops being pushed to the transport layer (if not simply ignored); these decisions have effectively legislated for the sort of resource exploitation attacks that are a problem today. We argue that while end-to-end design is vital to maximise freedom to innovate, the network must enforce a higher degree of mutual consent between communicating hosts.
