Thanks for pointing this significant conceptual difference. Is there a way to predict the amount of overhead or the in-band TCP data that can be hold ?
in my tests I'm doing the following: net.ipv4.tcp_adv_win_scale = 14 net.ipv4.tcp_rmem = 4096 87380 X*2 net.ipv4.tcp_wmem = 4096 65536 X*2 net.core.rmem_max = X*2 + 10 * 2^20 # 10MB available over what i use net.core.wmem_max = X*2 + 10 * 2^20 # same on both the receiver and sender pc's.. doing this the cwnd at the sender grows till X/RTT otherwise it is limited by the receiver in this way i get a good approximation - : send the line "unsubscribe linux-net" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
