I am sympathetic to Kazuho's argument that this language seems to require state that a receiver may not have. I think this is easily resolvable though. If a packet received is either a duplicate or if it is to the left of the receiver's "window" (the lowest packet number that the receiver is willing to receive and process), the receiver drops it. I think this handles the cases where the receiver may not be able to dedup, but the outcome is the same -- the receiver drops the packet.
