Angelo, this work is very interesting, I'm deep in your's and related papers on this topic right now :-) It would be very interesting to see how westwood+ compares to F-RTO, in particular over wireless networks since both purport to improve things over such technologies. Since F-RTO is available in both 2.4.x and 2.6.x kernels now, such experiments should be easy to run. Also, it would be interesting, once we have a working TCP Vegas implementation again, to see how combinations of Westwood+/VEGAS and F-RTO/Vegas compared to flat new-reno. In particular, since VEGAS attempts to avoid the packet loss from happening in the first place, and if it does still happen Westwood+/F-RTO will handle them more gracefully, the overall result should be something approaching the sum of the parts :-) Also, it would be very interesting to consider in depth whether the BW estimation filtering done by Westwood+ to thwart ACK compression could help TCP Vegas's BW estmiators as well. Baring some huge problem, I would be happy to put a cleaned up Westwood+ in the kernel, available always, but disabled by default via sysctl (as I believe is implemented in your patch) until we have more experimental results. - : 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
