That looks interesting - without reading the papers a few questions are developing in my brain cells; for example it looks very similar to what the chelsio NICs claim to do (which could be a good thing for TCP). Whenever i see someone implementing something in hardware, i always get flushes of "patents". Denys, one of the things i have noticed with iperf is it tries to be clever and "probe" the available bandwidth first. So you may not get the most optimal use of of your bandwidth. Try something like pktgen, its quiet accurate in its measurements. Just add a tc drop rule on the receiver to get the accounting. cheers, jamal - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
