The IPv6 header has a eld called the Flow Label field, which was included to help identify flows of packets, mainly for Quality of Service purposes. We propose using this field, and its randomly generated value, as another piece of state to lter related packets in a TCP connection. This will only be possible if the Flow Label field actually remains constant for the duration of connections and will only be useful if the Flow Label is set in a unpredictable way.
