Yes. A duplicate packet for the missing packet is not seen. The receiver 'misses' a packet; starts sending out tons of dup acks (for all packets in flight and queued up due to bufferbloat), and then way later, the packet does come in (after the RTT caused by bufferbloat; indicating it is the 'resent' packet). _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat
