Frankly, that sounds like an implementation issue. If we're willing to set IW=10, it seems like one should be able to send the initial burst, or at least the first retransmission, with messages of several sizes and see what works. In other words, if the MSS is 9K (I wish), send a 9K, a 4K, a 1500 byte IP datagram (eg 1440 byte payload), and 1280. If we get an Ack in the subsequent RTT acknowledging 8192 bytes, we learned something, and if the only Ack acknowledges 1280, we learned something. -------------------------------------------------------------------- IETF IPv6 working group mailing list [email protected] Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
