Hi, What if the retransmitted packets triggered by 3 dup acks get lost? can I re-trigger the sender to get it by sending again 3 dup acks, or I can just wait for the sender to timeout? I do not want time out since it is too long, any other ways I can let the sender to send them immediately? Thanks, -Haijin - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
