I'm curious what you mean about BSD. I would be very cautious about turning on Vegas by default. In certain cases, it is exactly the right thing to do. However, in many cases it is not. Vegas will end up losing when competing against regular Reno-ish congestion control. Vegas also has issues with timer granularity, and tuning its parameters can be quite tricky. There are a number of unusual failure modes as well, such as responding to congestion on the reverse path, or caused by cross traffic. -John - : 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
