Hi, Does Linux include any reduction of TCP transmission rate over Ethernet when no actual packet losses are present? I've heard that some unices cut TCP's congestion window in half when ethernet collision occurs or interface queue fills up (however no packet loss has occured). The reason I'm asking is that I'm playing with application-level congestion control running over UDP and it beats TCP pretty badly over LAN. If the above is true, when the situation becomes clear as there is no way how the kernel can inform a UDP application about ethernet details. Thanks, Andrei - : 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
