No to be nit-picky, but :) "for high-bandwidth, high-latency networks." That isn't 100% true - check http://www.psc.edu/networking/projects/hpn-ssh/papers/i2mm-hpn-ssh.ppt . As the BDP is calculated based on BW and RTT, higher RTTs would surely mean higher BDP values and bigger buffers - but even in high bandwith, low-latency networks you should see an improvement on the transfer rate.

Is it really as cool as it looks?Yes, for high-bandwidth, high-latency networks. For example we were transferring files from Los Angeles to New York over Internet2. Without HPN, scp was going at 900KB/s. With the HPN patches, scp sped up to 20MB/s. -- Matt _______________________________________________ Sent through the nmap-dev mailing list http://cgi.insecure.org/mailman/listinfo/nmap-dev Archived at http://SecLists.Org
